+File::Listing - parse directory listing
+
+=head1 SYNOPSIS
+
+ use File::Listing qw(parse_dir);
+ $ENV{LANG} = "C"; # dates in non-English locales not supported
+ for (parse_dir(`ls -l`)) {
+ ($name, $type, $size, $mtime, $mode) = @$_;
+ next if $type ne 'f'; # plain file
+ #...
+ }
+
+ # directory listing can also be read from a file
+ open(LISTING, "zcat ls-lR.gz|");
+ $dir = parse_dir(\*LISTING, '+0000');
+
+=head1 DESCRIPTION
+
+This module exports a single function called parse_dir(), which can be
+used to parse directory listings.
+
+The first parameter to parse_dir() is the directory listing to parse.
+It can be a scalar, a reference to an array of directory lines or a
+glob representing a filehandle to read the directory listing from.
+
+The second parameter is the time zone to use when parsing time stamps
+in the listing. If this value is undefined, then the local time zone is
+assumed.
+
+The third parameter is the type of listing to assume. Currently
+supported formats are 'unix', 'apache' and 'dosftp'. The default
+value 'unix'. Ideally, the listing type should be determined
+automatically.
+
+The fourth parameter specifies how unparseable lines should be treated.
+Values can be 'ignore', 'warn' or a code reference. Warn means that
+the perl warn() function will be called. If a code reference is
+passed, then this routine will be called and the return value from it
+will be incorporated in the listing. The default is 'ignore'.
+
+Only the first parameter is mandatory.
+
+The return value from parse_dir() is a list of directory entries. In
+a scalar context the return value is a reference to the list. The
+directory entries are represented by an array consisting of [
+$filename, $filetype, $filesize, $filetime, $filemode ]. The
+$filetype value is one of the letters 'f', 'd', 'l' or '?'. The
+$filetime value is the seconds since Jan 1, 1970. The
+$filemode is a bitmask like the mode returned by stat().
+
+=head1 CREDITS
+
+Based on lsparse.pl (from Lee McLoughlin's ftp mirror package) and
+Net::FTP's parse_dir (Graham Barr).

+=head1 NAME
+
+HTML::Entities - Encode or decode strings with HTML entities
+
+=head1 SYNOPSIS
+
+ use HTML::Entities;
+
+ $a = "V&aring;re norske tegn b&oslash;r &#230res";
+ decode_entities($a);
+ encode_entities($a, "\200-\377");
+
+For example, this:
+
+ $input = "vis-à-vis Beyoncé's naïve\npapier-mâché résumé";
+ print encode_entities($input), "\n"
+
+Prints this out:
+
+ vis-&agrave;-vis Beyonc&eacute;'s na&iuml;ve
+ papier-m&acirc;ch&eacute; r&eacute;sum&eacute;
+
+=head1 DESCRIPTION
+
+This module deals with encoding and decoding of strings with HTML
+character entities. The module provides the following functions:
+
+=over 4
+
+=item decode_entities( $string, ... )
+
+This routine replaces HTML entities found in the $string with the
+corresponding Unicode character. Under perl 5.6 and earlier only
+characters in the Latin-1 range are replaced. Unrecognized
+entities are left alone.
+
+If multiple strings are provided as argument they are each decoded
+separately and the same number of strings are returned.
+
+If called in void context the arguments are decoded in-place.
+
+This routine is exported by default.
+
+=item _decode_entities( $string, \%entity2char )
+
+=item _decode_entities( $string, \%entity2char, $expand_prefix )
+
+This will in-place replace HTML entities in $string. The %entity2char
+hash must be provided. Named entities not found in the %entity2char
+hash are left alone. Numeric entities are expanded unless their value
+overflow.
+
+The keys in %entity2char are the entity names to be expanded and their
+values are what they should expand into. The values do not have to be
+single character strings. If a key has ";" as suffix,
+then occurrences in $string are only expanded if properly terminated
+with ";". Entities without ";" will be expanded regardless of how
+they are terminated for compatibility with how common browsers treat
+entities in the Latin-1 range.
+
+If $expand_prefix is TRUE then entities without trailing ";" in
+%entity2char will even be expanded as a prefix of a longer
+unrecognized name. The longest matching name in %entity2char will be
+used. This is mainly present for compatibility with an MSIE
+misfeature.
+
+ $string = "foo&nbspbar";
+ _decode_entities($string, { nb => "@", nbsp => "\xA0" }, 1);
+ print $string; # will print "foo bar"
+
+This routine is exported by default.
+
+=item encode_entities( $string )
+
+=item encode_entities( $string, $unsafe_chars )
+
+This routine replaces unsafe characters in $string with their entity
+representation. A second argument can be given to specify which characters to
+consider unsafe. The unsafe characters is specified using the regular
+expression character class syntax (what you find within brackets in regular
+expressions).
+
+The default set of characters to encode are control chars, high-bit chars, and
+the C<< < >>, C<< & >>, C<< > >>, C<< ' >> and C<< " >> characters. But this,
+for example, would encode I<just> the C<< < >>, C<< & >>, C<< > >>, and C<< "
+>> characters:
+
+ $encoded = encode_entities($input, '<>&"');
+
+and this would only encode non-plain ascii:
+
+ $encoded = encode_entities($input, '^\n\x20-\x25\x27-\x7e');
+
+This routine is exported by default.
+
+=item encode_entities_numeric( $string )
+
+=item encode_entities_numeric( $string, $unsafe_chars )
+
+This routine works just like encode_entities, except that the replacement
+entities are always C<&#xI<hexnum>;> and never C<&I<entname>;>. For
+example, C<encode_entities("r\xF4le")> returns "r&ocirc;le", but
+C<encode_entities_numeric("r\xF4le")> returns "r&#xF4;le".
+
+This routine is I<not> exported by default. But you can always
+export it with C<use HTML::Entities qw(encode_entities_numeric);>
+or even C<use HTML::Entities qw(:DEFAULT encode_entities_numeric);>
+
+=back
+
+All these routines modify the string passed as the first argument, if
+called in a void context. In scalar and array contexts, the encoded or
+decoded string is returned (without changing the input string).
+
+If you prefer not to import these routines into your namespace, you can
+call them as:
+
+ use HTML::Entities ();
+ $decoded = HTML::Entities::decode($a);
+ $encoded = HTML::Entities::encode($a);
+ $encoded = HTML::Entities::encode_numeric($a);
+
+The module can also export the %char2entity and the %entity2char
+hashes, which contain the mapping from all characters to the
+corresponding entities (and vice versa, respectively).

+=head1 NAME
+
+HTML::Filter - Filter HTML text through the parser
+
+=head1 NOTE
+
+B<This module is deprecated.> The C<HTML::Parser> now provides the
+functionally of C<HTML::Filter> much more efficiently with the the
+C<default> handler.
+
+=head1 SYNOPSIS
+
+ require HTML::Filter;
+ $p = HTML::Filter->new->parse_file("index.html");
+
+=head1 DESCRIPTION
+
+C<HTML::Filter> is an HTML parser that by default prints the
+original text of each HTML element (a slow version of cat(1) basically).
+The callback methods may be overridden to modify the filtering for some
+HTML elements and you can override output() method which is called to
+print the HTML text.
+
+C<HTML::Filter> is a subclass of C<HTML::Parser>. This means that
+the document should be given to the parser by calling the $p->parse()
+or $p->parse_file() methods.
+
+=head1 EXAMPLES
+
+The first example is a filter that will remove all comments from an
+HTML file. This is achieved by simply overriding the comment method
+to do nothing.

+
+The second example shows a filter that will remove any E<lt>TABLE>s
+found in the HTML file. We specialize the start() and end() methods
+to count table tags and then make output not happen when inside a
+table.
+
+ package TableStripper;

+ }
+
+ sub output
+ {
+ my $self = shift;
+ unless ($self->{table_seen}) {
+ $self->SUPER::output(@_);
+ }
+ }
+
+If you want to collect the parsed text internally you might want to do
+something like this:
+
+ package FilterIntoString;
+ require HTML::Filter;
+ @ISA=qw(HTML::Filter);
+ sub output { push(@{$_[0]->{fhtml}}, $_[1]) }
+ sub filtered_html { join("", @{$_[0]->{fhtml}}) }

+=head1 NAME
+
+HTML::Form - Class that represents an HTML form element
+
+=head1 SYNOPSIS
+
+ use HTML::Form;
+ $form = HTML::Form->parse($html, $base_uri);
+ $form->value(query => "Perl");
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $response = $ua->request($form->click);
+
+=head1 DESCRIPTION
+
+Objects of the C<HTML::Form> class represents a single HTML
+C<E<lt>formE<gt> ... E<lt>/formE<gt>> instance. A form consists of a
+sequence of inputs that usually have names, and which can take on
+various values. The state of a form can be tweaked and it can then be
+asked to provide C<HTTP::Request> objects that can be passed to the
+request() method of C<LWP::UserAgent>.
+
+The following methods are available:
+
+=over 4
+
+=item @forms = HTML::Form->parse( $html_document, $base_uri )
+
+=item @forms = HTML::Form->parse( $html_document, base => $base_uri, %opt )
+
+=item @forms = HTML::Form->parse( $response, %opt )
+
+The parse() class method will parse an HTML document and build up
+C<HTML::Form> objects for each <form> element found. If called in scalar
+context only returns the first <form>. Returns an empty list if there
+are no forms to be found.
+
+The required arguments is the HTML document to parse ($html_document) and the
+URI used to retrieve the document ($base_uri). The base URI is needed to resolve
+relative action URIs. The provided HTML document should be a Unicode string
+(or US-ASCII).
+
+By default HTML::Form assumes that the original document was UTF-8 encoded and
+thus encode forms that don't specify an explict I<accept-charset> as UTF-8.
+The charset assumed can be overridden by providing the C<charset> option to
+parse(). It's a good idea to be explict about this parameter as well, thus
+the recommended simplest invocation becomes:
+
+ my @forms = HTML::Form->parse(
+ Encode::decode($encoding, $html_document_bytes),
+ base => $base_uri,
+ charset => $encoding,
+ );
+
+If the document was retrieved with LWP then the response object provide methods
+to obtain a proper value for C<base> and C<charset>:
+
+ my $ua = LWP::UserAgent->new;
+ my $response = $ua->get("http://www.example.com/form.html");
+ my @forms = HTML::Form->parse($response->decoded_content,
+ base => $response->base,
+ charset => $response->content_charset,
+ );
+
+In fact, the parse() method can parse from an C<HTTP::Response> object
+directly, so the example above can be more conveniently written as:
+
+ my $ua = LWP::UserAgent->new;
+ my $response = $ua->get("http://www.example.com/form.html");
+ my @forms = HTML::Form->parse($response);
+
+Note that any object that implements a decoded_content(), base() and
+content_charset() method with similar behaviour as C<HTTP::Response> will do.
+
+Additional options might be passed in to control how the parse method
+behaves. The following are all the options currently recognized:
+
+=over
+
+=item C<< base => $uri >>
+
+This is the URI used to retrive the original document. This option is not optional ;-)
+
+=item C<< charset => $str >>
+
+Specify what charset the original document was encoded in. This is used as
+the default for accept_charset. If not provided this defaults to "UTF-8".
+
+=item C<< verbose => $bool >>
+
+Warn (print messages to STDERR) about any bad HTML form constructs found.
+You can trap these with $SIG{__WARN__}.
+
+=item C<< strict => $bool >>
+
+Initialize any form objects with the given strict attribute.

+
+If called with a single argument then it returns the value or values
+of inputs with the given name. If called in scalar context only the

+or if any of the values provided does not fit. Values can also be

+A click coordinate pair can also be provided, but this only makes a

+=head1 INPUTS
+
+An C<HTML::Form> objects contains a sequence of I<inputs>. References to
+the inputs can be obtained with the $form->inputs or $form->find_input
+methods.
+
+Note that there is I<not> a one-to-one correspondence between input
+I<objects> and E<lt>inputE<gt> I<elements> in the HTML document. An
+input object basically represents a name/value pair, so when multiple
+HTML elements contribute to the same name/value pair in the submitted
+form they are combined.
+
+The input elements that are mapped one-to-one are "text", "textarea",
+"password", "hidden", "file", "image", "submit" and "checkbox". For
+the "radio" and "option" inputs the story is not as simple: All
+E<lt>input type="radio"E<gt> elements with the same name will
+contribute to the same input radio object. The number of radio input
+objects will be the same as the number of distinct names used for the
+E<lt>input type="radio"E<gt> elements. For a E<lt>selectE<gt> element
+without the C<multiple> attribute there will be one input object of
+type of "option". For a E<lt>select multipleE<gt> element there will
+be one input object for each contained E<lt>optionE<gt> element. Each
+one of these option objects will have the same name.
+
+The following methods are available for the I<input> objects:

+HTML::HeadParser - Parse <HEAD> section of a HTML document
+
+=head1 SYNOPSIS
+
+ require HTML::HeadParser;
+ $p = HTML::HeadParser->new;
+ $p->parse($text) and print "not finished";
+
+ $p->header('Title') # to access <title>....</title>

+ $p->header('Foo') # to access <meta http-equiv="Foo" content="...">
+ $p->header('X-Meta-Author') # to access <meta name="author" content="...">
+ $p->header('X-Meta-Charset') # to access <meta charset="...">
+
+=head1 DESCRIPTION
+
+The C<HTML::HeadParser> is a specialized (and lightweight)
+C<HTML::Parser> that will only parse the E<lt>HEAD>...E<lt>/HEAD>
+section of an HTML document. The parse() method
+will return a FALSE value as soon as some E<lt>BODY> element or body
+text are found, and should not be called again after this.
+
+Note that the C<HTML::HeadParser> might get confused if raw undecoded
+UTF-8 is passed to the parse() method. Make sure the strings are
+properly decoded before passing them on.
+
+The C<HTML::HeadParser> keeps a reference to a header object, and the
+parser will update this header object as the various elements of the
+E<lt>HEAD> section of the HTML document are recognized. The following
+header fields are affected:
+
+=over 4
+
+=item Content-Base:
+
+The I<Content-Base> header is initialized from the E<lt>base
+href="..."> element.
+
+=item Title:
+
+The I<Title> header is initialized from the E<lt>title>...E<lt>/title>
+element.
+
+=item Isindex:
+
+The I<Isindex> header will be added if there is a E<lt>isindex>
+element in the E<lt>head>. The header value is initialized from the
+I<prompt> attribute if it is present. If no I<prompt> attribute is
+given it will have '?' as the value.
+
+=item X-Meta-Foo:
+
+All E<lt>meta> elements containing a C<name> attribute will result in
+headers using the prefix C<X-Meta-> appended with the value of the
+C<name> attribute as the name of the header, and the value of the
+C<content> attribute as the pushed header value.
+
+E<lt>meta> elements containing a C<http-equiv> attribute will result
+in headers as in above, but without the C<X-Meta-> prefix in the
+header name.
+
+E<lt>meta> elements containing a C<charset> attribute will result in
+an C<X-Meta-Charset> header, using the value of the C<charset>
+attribute as the pushed header value.

+
+The following methods (in addition to those provided by the

+
+=head1 DESCRIPTION
+
+I<HTML::LinkExtor> is an HTML parser that extracts links from an
+HTML document. The I<HTML::LinkExtor> is a subclass of
+I<HTML::Parser>. This means that the document should be given to the
+parser by calling the $p->parse() or $p->parse_file() methods.

+
+The constructor takes two optional arguments. The first is a reference
+to a callback routine. It will be called as links are found. If a
+callback is not provided, then links are just accumulated internally
+and can be retrieved by calling the $p->links() method.
+
+The $base argument is an optional base URL used to absolutize all URLs found.
+You need to have the I<URI> module installed if you provide $base.
+
+The callback is called with the lowercase tag name as first argument,
+and then all link attributes as separate key/value pairs. All
+non-link attributes are removed.

+
+Returns a list of all links found in the document. The returned
+values will be anonymous arrays with the following elements:

+
+The $p->links method will also truncate the internal link list. This
+means that if the method is called twice without any parsing
+between them the second call will return an empty list.
+
+Also note that $p->links will always be empty if a callback routine
+was provided when the I<HTML::LinkExtor> was created.

+=head1 DESCRIPTION
+
+Objects of the C<HTML::Parser> class will recognize markup and
+separate it from plain text (alias data content) in HTML
+documents. As different kinds of markup and text are recognized, the
+corresponding event handlers are invoked.
+
+C<HTML::Parser> is not a generic SGML parser. We have tried to
+make it able to deal with the HTML that is actually "out there", and
+it normally parses as closely as possible to the way the popular web
+browsers do it instead of strictly following one of the many HTML
+specifications from W3C. Where there is disagreement, there is often
+an option that you can enable to get the official behaviour.
+
+The document to be parsed may be supplied in arbitrary chunks. This
+makes on-the-fly parsing as documents are received from the network
+possible.
+
+If event driven parsing does not feel right for your application, you
+might want to use C<HTML::PullParser>. This is an C<HTML::Parser>
+subclass that allows a more conventional program structure.
+
+
+=head1 METHODS
+
+The following method is used to construct a new C<HTML::Parser> object:
+
+=over
+
+=item $p = HTML::Parser->new( %options_and_handlers )
+
+This class method creates a new C<HTML::Parser> object and
+returns it. Key/value argument pairs may be provided to assign event
+handlers or initialize parser options. The handlers and parser
+options can also be set or modified later by the method calls described below.
+
+If a top level key is in the form "<event>_h" (e.g., "text_h") then it
+assigns a handler to that event, otherwise it initializes a parser
+option. The event handler specification value must be an array
+reference. Multiple handlers may also be assigned with the 'handlers
+=> [%handlers]' option. See examples below.
+
+If new() is called without any arguments, it will create a parser that
+uses callback methods compatible with version 2 of C<HTML::Parser>.
+See the section on "version 2 compatibility" below for details.
+
+The special constructor option 'api_version => 2' can be used to
+initialize version 2 callbacks while still setting other options and
+handlers. The 'api_version => 3' option can be used if you don't want
+to set any options and don't want to fall back to v2 compatible
+mode.
+
+Examples:
+
+ $p = HTML::Parser->new(api_version => 3,
+ text_h => [ sub {...}, "dtext" ]);
+
+This creates a new parser object with a text event handler subroutine
+that receives the original text with general entities decoded.
+
+ $p = HTML::Parser->new(api_version => 3,
+ start_h => [ 'my_start', "self,tokens" ]);
+
+This creates a new parser object with a start event handler method
+that receives the $p and the tokens array.
+
+ $p = HTML::Parser->new(api_version => 3,
+ handlers => { text => [\@array, "event,text"],
+ comment => [\@array, "event,text"],
+ });
+
+This creates a new parser object that stores the event type and the
+original text in @array for text and comment events.
+
+=back
+
+The following methods feed the HTML document
+to the C<HTML::Parser> object:
+
+=over
+
+=item $p->parse( $string )
+
+Parse $string as the next chunk of the HTML document. Handlers invoked should
+not attempt to modify the $string in-place until $p->parse returns.
+
+If an invoked event handler aborts parsing by calling $p->eof, then $p->parse()
+will return a FALSE value. Otherwise the return value is a reference to the
+parser object ($p).
+
+=item $p->parse( $code_ref )
+
+If a code reference is passed as the argument to be parsed, then the
+chunks to be parsed are obtained by invoking this function repeatedly.
+Parsing continues until the function returns an empty (or undefined)
+result. When this happens $p->eof is automatically signaled.
+
+Parsing will also abort if one of the event handlers calls $p->eof.
+
+The effect of this is the same as:
+
+ while (1) {
+ my $chunk = &$code_ref();
+ if (!defined($chunk) || !length($chunk)) {
+ $p->eof;
+ return $p;
+ }
+ $p->parse($chunk) || return undef;
+ }
+
+But it is more efficient as this loop runs internally in XS code.
+
+=item $p->parse_file( $file )
+
+Parse text directly from a file. The $file argument can be a
+filename, an open file handle, or a reference to an open file
+handle.
+
+If $file contains a filename and the file can't be opened, then the
+method returns an undefined value and $! tells why it failed.
+Otherwise the return value is a reference to the parser object.
+
+If a file handle is passed as the $file argument, then the file will
+normally be read until EOF, but not closed.
+
+If an invoked event handler aborts parsing by calling $p->eof,
+then $p->parse_file() may not have read the entire file.
+
+On systems with multi-byte line terminators, the values passed for the
+offset and length argspecs may be too low if parse_file() is called on
+a file handle that is not in binary mode.
+
+If a filename is passed in, then parse_file() will open the file in
+binary mode.
+
+=item $p->eof
+
+Signals the end of the HTML document. Calling the $p->eof method
+outside a handler callback will flush any remaining buffered text
+(which triggers the C<text> event if there is any remaining text).
+
+Calling $p->eof inside a handler will terminate parsing at that point
+and cause $p->parse to return a FALSE value. This also terminates
+parsing by $p->parse_file().
+
+After $p->eof has been called, the parse() and parse_file() methods
+can be invoked to feed new documents with the parser object.
+
+The return value from eof() is a reference to the parser object.
+
+=back
+
+
+Most parser options are controlled by boolean attributes.
+Each boolean attribute is enabled by calling the corresponding method
+with a TRUE argument and disabled with a FALSE argument. The
+attribute value is left unchanged if no argument is given. The return
+value from each method is the old attribute value.
+
+Methods that can be used to get and/or set parser options are:
+
+=over
+
+=item $p->attr_encoded
+
+=item $p->attr_encoded( $bool )
+
+By default, the C<attr> and C<@attr> argspecs will have general
+entities for attribute values decoded. Enabling this attribute leaves
+entities alone.
+
+=item $p->backquote
+
+=item $p->backquote( $bool )
+
+By default, only ' and " are recognized as quote characters around
+attribute values. MSIE also recognizes backquotes for some reason.
+Enabling this attribute provides compatibility with this behaviour.
+
+=item $p->boolean_attribute_value( $val )
+
+This method sets the value reported for boolean attributes inside HTML
+start tags. By default, the name of the attribute is also used as its
+value. This affects the values reported for C<tokens> and C<attr>
+argspecs.
+
+=item $p->case_sensitive
+
+=item $p->case_sensitive( $bool )
+
+By default, tagnames and attribute names are down-cased. Enabling this
+attribute leaves them as found in the HTML source document.
+
+=item $p->closing_plaintext
+
+=item $p->closing_plaintext( $bool )
+
+By default, "plaintext" element can never be closed. Everything up to
+the end of the document is parsed in CDATA mode. This historical
+behaviour is what at least MSIE does. Enabling this attribute makes
+closing "</plaintext>" tag effective and the parsing process will resume
+after seeing this tag. This emulates early gecko-based browsers.
+
+=item $p->empty_element_tags
+
+=item $p->empty_element_tags( $bool )
+
+By default, empty element tags are not recognized as such and the "/"
+before ">" is just treated like a normal name character (unless
+C<strict_names> is enabled). Enabling this attribute make
+C<HTML::Parser> recognize these tags.
+
+Empty element tags look like start tags, but end with the character
+sequence "/>" instead of ">". When recognized by C<HTML::Parser> they
+cause an artificial end event in addition to the start event. The
+C<text> for the artificial end event will be empty and the C<tokenpos>
+array will be undefined even though the the token array will have one
+element containing the tag name.
+
+=item $p->marked_sections
+
+=item $p->marked_sections( $bool )
+
+By default, section markings like <![CDATA[...]]> are treated like
+ordinary text. When this attribute is enabled section markings are
+honoured.
+
+There are currently no events associated with the marked section
+markup, but the text can be returned as C<skipped_text>.
+
+=item $p->strict_comment
+
+=item $p->strict_comment( $bool )
+
+By default, comments are terminated by the first occurrence of "-->".
+This is the behaviour of most popular browsers (like Mozilla, Opera and
+MSIE), but it is not correct according to the official HTML
+standard. Officially, you need an even number of "--" tokens before
+the closing ">" is recognized and there may not be anything but
+whitespace between an even and an odd "--".
+
+The official behaviour is enabled by enabling this attribute.
+
+Enabling of 'strict_comment' also disables recognizing these forms as
+comments:
+
+ </ comment>
+ <! comment>
+
+
+=item $p->strict_end
+
+=item $p->strict_end( $bool )
+
+By default, attributes and other junk are allowed to be present on end tags in a
+manner that emulates MSIE's behaviour.
+
+The official behaviour is enabled with this attribute. If enabled,
+only whitespace is allowed between the tagname and the final ">".
+
+=item $p->strict_names
+
+=item $p->strict_names( $bool )
+
+By default, almost anything is allowed in tag and attribute names.
+This is the behaviour of most popular browsers and allows us to parse
+some broken tags with invalid attribute values like:
+
+ <IMG SRC=newprevlstGr.gif ALT=[PREV LIST] BORDER=0>
+
+By default, "LIST]" is parsed as a boolean attribute, not as
+part of the ALT value as was clearly intended. This is also what
+Mozilla sees.
+
+The official behaviour is enabled by enabling this attribute. If
+enabled, it will cause the tag above to be reported as text
+since "LIST]" is not a legal attribute name.
+
+=item $p->unbroken_text
+
+=item $p->unbroken_text( $bool )
+
+By default, blocks of text are given to the text handler as soon as
+possible (but the parser takes care always to break text at a
+boundary between whitespace and non-whitespace so single words and
+entities can always be decoded safely). This might create breaks that
+make it hard to do transformations on the text. When this attribute is
+enabled, blocks of text are always reported in one piece. This will
+delay the text event until the following (non-text) event has been
+recognized by the parser.
+
+Note that the C<offset> argspec will give you the offset of the first
+segment of text and C<length> is the combined length of the segments.
+Since there might be ignored tags in between, these numbers can't be
+used to directly index in the original document file.
+
+=item $p->utf8_mode
+
+=item $p->utf8_mode( $bool )
+
+Enable this option when parsing raw undecoded UTF-8. This tells the
+parser that the entities expanded for strings reported by C<attr>,
+C<@attr> and C<dtext> should be expanded as decoded UTF-8 so they end
+up compatible with the surrounding text.
+
+If C<utf8_mode> is enabled then it is an error to pass strings
+containing characters with code above 255 to the parse() method, and
+the parse() method will croak if you try.
+
+Example: The Unicode character "\x{2665}" is "\xE2\x99\xA5" when UTF-8
+encoded. The character can also be represented by the entity
+"&hearts;" or "&#x2665". If we feed the parser:
+
+ $p->parse("\xE2\x99\xA5&hearts;");
+
+then C<dtext> will be reported as "\xE2\x99\xA5\x{2665}" without
+C<utf8_mode> enabled, but as "\xE2\x99\xA5\xE2\x99\xA5" when enabled.
+The later string is what you want.
+
+This option is only available with perl-5.8 or better.
+
+=item $p->xml_mode
+
+=item $p->xml_mode( $bool )
+
+Enabling this attribute changes the parser to allow some XML
+constructs. This enables the behaviour controlled by individually by
+the C<case_sensitive>, C<empty_element_tags>, C<strict_names> and
+C<xml_pic> attributes and also suppresses special treatment of
+elements that are parsed as CDATA for HTML.
+
+=item $p->xml_pic
+
+=item $p->xml_pic( $bool )
+
+By default, I<processing instructions> are terminated by ">". When
+this attribute is enabled, processing instructions are terminated by
+"?>" instead.
+
+=back
+
+As markup and text is recognized, handlers are invoked. The following
+method is used to set up handlers for different events:
+
+=over
+
+=item $p->handler( event => \&subroutine, $argspec )
+
+=item $p->handler( event => $method_name, $argspec )
+
+=item $p->handler( event => \@accum, $argspec )
+
+=item $p->handler( event => "" );
+
+=item $p->handler( event => undef );
+
+=item $p->handler( event );
+
+This method assigns a subroutine, method, or array to handle an event.
+
+Event is one of C<text>, C<start>, C<end>, C<declaration>, C<comment>,
+C<process>, C<start_document>, C<end_document> or C<default>.
+
+The C<\&subroutine> is a reference to a subroutine which is called to handle
+the event.
+
+The C<$method_name> is the name of a method of $p which is called to handle
+the event.
+
+The C<@accum> is an array that will hold the event information as
+sub-arrays.
+
+If the second argument is "", the event is ignored.
+If it is undef, the default handler is invoked for the event.
+
+The C<$argspec> is a string that describes the information to be reported
+for the event. Any requested information that does not apply to a
+specific event is passed as C<undef>. If argspec is omitted, then it
+is left unchanged.
+
+The return value from $p->handler is the old callback routine or a
+reference to the accumulator array.
+
+Any return values from handler callback routines/methods are always
+ignored. A handler callback can request parsing to be aborted by
+invoking the $p->eof method. A handler callback is not allowed to
+invoke the $p->parse() or $p->parse_file() method. An exception will
+be raised if it tries.
+
+Examples:
+
+ $p->handler(start => "start", 'self, attr, attrseq, text' );
+
+This causes the "start" method of object $p to be called for 'start' events.
+The callback signature is $p->start(\%attr, \@attr_seq, $text).
+
+ $p->handler(start => \&start, 'attr, attrseq, text' );
+
+This causes subroutine start() to be called for 'start' events.
+The callback signature is start(\%attr, \@attr_seq, $text).
+
+ $p->handler(start => \@accum, '"S", attr, attrseq, text' );
+
+This causes 'start' event information to be saved in @accum.
+The array elements will be ['S', \%attr, \@attr_seq, $text].
+
+ $p->handler(start => "");
+
+This causes 'start' events to be ignored. It also suppresses
+invocations of any default handler for start events. It is in most
+cases equivalent to $p->handler(start => sub {}), but is more
+efficient. It is different from the empty-sub-handler in that
+C<skipped_text> is not reset by it.
+
+ $p->handler(start => undef);
+
+This causes no handler to be associated with start events.
+If there is a default handler it will be invoked.
+
+=back
+
+Filters based on tags can be set up to limit the number of events
+reported. The main bottleneck during parsing is often the huge number
+of callbacks made from the parser. Applying filters can improve
+performance significantly.
+
+The following methods control filters:
+
+=over
+
+=item $p->ignore_elements( @tags )
+
+Both the C<start> event and the C<end> event as well as any events that
+would be reported in between are suppressed. The ignored elements can
+contain nested occurrences of itself. Example:
+
+ $p->ignore_elements(qw(script style));
+
+The C<script> and C<style> tags will always nest properly since their
+content is parsed in CDATA mode. For most other tags
+C<ignore_elements> must be used with caution since HTML is often not
+I<well formed>.
+
+=item $p->ignore_tags( @tags )
+
+Any C<start> and C<end> events involving any of the tags given are
+suppressed. To reset the filter (i.e. don't suppress any C<start> and
+C<end> events), call C<ignore_tags> without an argument.
+
+=item $p->report_tags( @tags )
+
+Any C<start> and C<end> events involving any of the tags I<not> given
+are suppressed. To reset the filter (i.e. report all C<start> and
+C<end> events), call C<report_tags> without an argument.
+
+=back
+
+Internally, the system has two filter lists, one for C<report_tags>
+and one for C<ignore_tags>, and both filters are applied. This
+effectively gives C<ignore_tags> precedence over C<report_tags>.
+
+Examples:
+
+ $p->ignore_tags(qw(style));
+ $p->report_tags(qw(script style));
+
+results in only C<script> events being reported.
+
+=head2 Argspec
+
+Argspec is a string containing a comma-separated list that describes
+the information reported by the event. The following argspec
+identifier names can be used:
+
+=over
+
+=item C<attr>
+
+Attr causes a reference to a hash of attribute name/value pairs to be
+passed.
+
+Boolean attributes' values are either the value set by
+$p->boolean_attribute_value, or the attribute name if no value has been
+set by $p->boolean_attribute_value.
+
+This passes undef except for C<start> events.
+
+Unless C<xml_mode> or C<case_sensitive> is enabled, the attribute
+names are forced to lower case.
+
+General entities are decoded in the attribute values and
+one layer of matching quotes enclosing the attribute values is removed.
+
+The Unicode character set is assumed for entity decoding. With Perl
+version 5.6 or earlier only the Latin-1 range is supported, and
+entities for characters outside the range 0..255 are left unchanged.
+
+=item C<@attr>
+
+Basically the same as C<attr>, but keys and values are passed as
+individual arguments and the original sequence of the attributes is
+kept. The parameters passed will be the same as the @attr calculated
+here:
+
+ @attr = map { $_ => $attr->{$_} } @$attrseq;
+
+assuming $attr and $attrseq here are the hash and array passed as the
+result of C<attr> and C<attrseq> argspecs.
+
+This passes no values for events besides C<start>.
+
+=item C<attrseq>
+
+Attrseq causes a reference to an array of attribute names to be
+passed. This can be useful if you want to walk the C<attr> hash in
+the original sequence.
+
+This passes undef except for C<start> events.
+
+Unless C<xml_mode> or C<case_sensitive> is enabled, the attribute
+names are forced to lower case.
+
+=item C<column>
+
+Column causes the column number of the start of the event to be passed.
+The first column on a line is 0.
+
+=item C<dtext>
+
+Dtext causes the decoded text to be passed. General entities are
+automatically decoded unless the event was inside a CDATA section or
+was between literal start and end tags (C<script>, C<style>,
+C<xmp>, C<iframe>, C<title>, C<textarea> and C<plaintext>).
+
+The Unicode character set is assumed for entity decoding. With Perl
+version 5.6 or earlier only the Latin-1 range is supported, and
+entities for characters outside the range 0..255 are left unchanged.
+
+This passes undef except for C<text> events.
+
+=item C<event>
+
+Event causes the event name to be passed.
+
+The event name is one of C<text>, C<start>, C<end>, C<declaration>,
+C<comment>, C<process>, C<start_document> or C<end_document>.
+
+=item C<is_cdata>
+
+Is_cdata causes a TRUE value to be passed if the event is inside a CDATA
+section or between literal start and end tags (C<script>,
+C<style>, C<xmp>, C<iframe>, C<title>, C<textarea> and C<plaintext>).
+
+if the flag is FALSE for a text event, then you should normally
+either use C<dtext> or decode the entities yourself before the text is
+processed further.
+
+=item C<length>
+
+Length causes the number of bytes of the source text of the event to
+be passed.
+
+=item C<line>
+
+Line causes the line number of the start of the event to be passed.
+The first line in the document is 1. Line counting doesn't start
+until at least one handler requests this value to be reported.
+
+=item C<offset>
+
+Offset causes the byte position in the HTML document of the start of
+the event to be passed. The first byte in the document has offset 0.
+
+=item C<offset_end>
+
+Offset_end causes the byte position in the HTML document of the end of
+the event to be passed. This is the same as C<offset> + C<length>.
+
+=item C<self>
+
+Self causes the current object to be passed to the handler. If the
+handler is a method, this must be the first element in the argspec.
+
+An alternative to passing self as an argspec is to register closures
+that capture $self by themselves as handlers. Unfortunately this
+creates circular references which prevent the HTML::Parser object
+from being garbage collected. Using the C<self> argspec avoids this
+problem.
+
+=item C<skipped_text>
+
+Skipped_text returns the concatenated text of all the events that have
+been skipped since the last time an event was reported. Events might
+be skipped because no handler is registered for them or because some
+filter applies. Skipped text also includes marked section markup,
+since there are no events that can catch it.
+
+If an C<"">-handler is registered for an event, then the text for this
+event is not included in C<skipped_text>. Skipped text both before
+and after the C<"">-event is included in the next reported
+C<skipped_text>.
+
+=item C<tag>
+
+Same as C<tagname>, but prefixed with "/" if it belongs to an C<end>
+event and "!" for a declaration. The C<tag> does not have any prefix
+for C<start> events, and is in this case identical to C<tagname>.
+
+=item C<tagname>
+
+This is the element name (or I<generic identifier> in SGML jargon) for
+start and end tags. Since HTML is case insensitive, this name is
+forced to lower case to ease string matching.
+
+Since XML is case sensitive, the tagname case is not changed when
+C<xml_mode> is enabled. The same happens if the C<case_sensitive> attribute
+is set.
+
+The declaration type of declaration elements is also passed as a tagname,
+even if that is a bit strange.
+In fact, in the current implementation tagname is
+identical to C<token0> except that the name may be forced to lower case.
+
+=item C<token0>
+
+Token0 causes the original text of the first token string to be
+passed. This should always be the same as $tokens->[0].
+
+For C<declaration> events, this is the declaration type.
+
+For C<start> and C<end> events, this is the tag name.
+
+For C<process> and non-strict C<comment> events, this is everything
+inside the tag.
+
+This passes undef if there are no tokens in the event.
+
+=item C<tokenpos>
+
+Tokenpos causes a reference to an array of token positions to be
+passed. For each string that appears in C<tokens>, this array
+contains two numbers. The first number is the offset of the start of
+the token in the original C<text> and the second number is the length
+of the token.
+
+Boolean attributes in a C<start> event will have (0,0) for the
+attribute value offset and length.
+
+This passes undef if there are no tokens in the event (e.g., C<text>)
+and for artificial C<end> events triggered by empty element tags.
+
+If you are using these offsets and lengths to modify C<text>, you
+should either work from right to left, or be very careful to calculate
+the changes to the offsets.
+
+=item C<tokens>
+
+Tokens causes a reference to an array of token strings to be passed.
+The strings are exactly as they were found in the original text,
+no decoding or case changes are applied.
+
+For C<declaration> events, the array contains each word, comment, and
+delimited string starting with the declaration type.
+
+For C<comment> events, this contains each sub-comment. If
+$p->strict_comments is disabled, there will be only one sub-comment.
+
+For C<start> events, this contains the original tag name followed by
+the attribute name/value pairs. The values of boolean attributes will
+be either the value set by $p->boolean_attribute_value, or the
+attribute name if no value has been set by
+$p->boolean_attribute_value.
+
+For C<end> events, this contains the original tag name (always one token).
+
+For C<process> events, this contains the process instructions (always one
+token).
+
+This passes C<undef> for C<text> events.
+
+=item C<text>
+
+Text causes the source text (including markup element delimiters) to be
+passed.
+
+=item C<undef>
+
+Pass an undefined value. Useful as padding where the same handler
+routine is registered for multiple events.
+
+=item C<'...'>
+
+A literal string of 0 to 255 characters enclosed
+in single (') or double (") quotes is passed as entered.
+
+=back
+
+The whole argspec string can be wrapped up in C<'@{...}'> to signal
+that the resulting event array should be flattened. This only makes a
+difference if an array reference is used as the handler target.
+Consider this example:
+
+ $p->handler(text => [], 'text');
+ $p->handler(text => [], '@{text}']);
+
+With two text events; C<"foo">, C<"bar">; then the first example will end
+up with [["foo"], ["bar"]] and the second with ["foo", "bar"] in
+the handler target array.
+
+
+=head2 Events
+
+Handlers for the following events can be registered:
+
+=over
+
+=item C<comment>
+
+This event is triggered when a markup comment is recognized.
+
+Example:
+
+ <!-- This is a comment -- -- So is this -->
+
+=item C<declaration>
+
+This event is triggered when a I<markup declaration> is recognized.
+
+For typical HTML documents, the only declaration you are
+likely to find is <!DOCTYPE ...>.
+
+Example:
+
+ <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
+ "http://www.w3.org/TR/html4/strict.dtd">
+
+DTDs inside <!DOCTYPE ...> will confuse HTML::Parser.
+
+=item C<default>
+
+This event is triggered for events that do not have a specific
+handler. You can set up a handler for this event to catch stuff you
+did not want to catch explicitly.
+
+=item C<end>
+
+This event is triggered when an end tag is recognized.
+
+Example:
+
+ </A>
+
+=item C<end_document>
+
+This event is triggered when $p->eof is called and after any remaining
+text is flushed. There is no document text associated with this event.
+
+=item C<process>
+
+This event is triggered when a processing instructions markup is
+recognized.
+
+The format and content of processing instructions are system and
+application dependent.
+
+Examples:
+
+ <? HTML processing instructions >
+ <? XML processing instructions ?>
+
+=item C<start>
+
+This event is triggered when a start tag is recognized.
+
+Example:
+
+ <A HREF="http://www.perl.com/">
+
+=item C<start_document>
+
+This event is triggered before any other events for a new document. A
+handler for it can be used to initialize stuff. There is no document
+text associated with this event.
+
+=item C<text>
+
+This event is triggered when plain text (characters) is recognized.
+The text may contain multiple lines. A sequence of text may be broken
+between several text events unless $p->unbroken_text is enabled.
+
+The parser will make sure that it does not break a word or a sequence
+of whitespace between two text events.
+
+=back
+
+=head2 Unicode
+
+C<HTML::Parser> can parse Unicode strings when running under
+perl-5.8 or better. If Unicode is passed to $p->parse() then chunks
+of Unicode will be reported to the handlers. The offset and length
+argspecs will also report their position in terms of characters.
+
+It is safe to parse raw undecoded UTF-8 if you either avoid decoding
+entities and make sure to not use I<argspecs> that do, or enable the
+C<utf8_mode> for the parser. Parsing of undecoded UTF-8 might be
+useful when parsing from a file where you need the reported offsets
+and lengths to match the byte offsets in the file.
+
+If a filename is passed to $p->parse_file() then the file will be read
+in binary mode. This will be fine if the file contains only ASCII or
+Latin-1 characters. If the file contains UTF-8 encoded text then care
+must be taken when decoding entities as described in the previous
+paragraph, but better is to open the file with the UTF-8 layer so that
+it is decoded properly:
+
+ open(my $fh, "<:utf8", "index.html") || die "...: $!";
+ $p->parse_file($fh);
+
+If the file contains text encoded in a charset besides ASCII, Latin-1
+or UTF-8 then decoding will always be needed.
+
+=head1 VERSION 2 COMPATIBILITY
+
+When an C<HTML::Parser> object is constructed with no arguments, a set
+of handlers is automatically provided that is compatible with the old
+HTML::Parser version 2 callback methods.
+
+This is equivalent to the following method calls:
+
+ $p->handler(start => "start", "self, tagname, attr, attrseq, text");
+ $p->handler(end => "end", "self, tagname, text");
+ $p->handler(text => "text", "self, text, is_cdata");
+ $p->handler(process => "process", "self, token0, text");
+ $p->handler(comment =>
+ sub {
+ my($self, $tokens) = @_;
+ for (@$tokens) {$self->comment($_);}},
+ "self, tokens");
+ $p->handler(declaration =>
+ sub {
+ my $self = shift;
+ $self->declaration(substr($_[0], 2, -1));},
+ "self, text");
+
+Setting up these handlers can also be requested with the "api_version =>
+2" constructor option.
+
+=head1 SUBCLASSING
+
+The C<HTML::Parser> class is subclassable. Parser objects are plain
+hashes and C<HTML::Parser> reserves only hash keys that start with
+"_hparser". The parser state can be set up by invoking the init()
+method, which takes the same arguments as new().
+
+=head1 EXAMPLES
+
+The first simple example shows how you might strip out comments from
+an HTML document. We achieve this by setting up a comment handler that
+does nothing and a default handler that will print out anything else:
+
+ use HTML::Parser;
+ HTML::Parser->new(default_h => [sub { print shift }, 'text'],
+ comment_h => [""],
+ )->parse_file(shift || die) || die $!;
+
+An alternative implementation is:
+
+ use HTML::Parser;
+ HTML::Parser->new(end_document_h => [sub { print shift },
+ 'skipped_text'],
+ comment_h => [""],
+ )->parse_file(shift || die) || die $!;
+
+This will in most cases be much more efficient since only a single
+callback will be made.
+
+The next example prints out the text that is inside the <title>
+element of an HTML document. Here we start by setting up a start
+handler. When it sees the title start tag it enables a text handler
+that prints any text found and an end handler that will terminate
+parsing as soon as the title end tag is seen:
+
+ use HTML::Parser ();
+
+ sub start_handler
+ {
+ return if shift ne "title";
+ my $self = shift;
+ $self->handler(text => sub { print shift }, "dtext");
+ $self->handler(end => sub { shift->eof if shift eq "title"; },
+ "tagname,self");
+ }
+
+ my $p = HTML::Parser->new(api_version => 3);
+ $p->handler( start => \&start_handler, "tagname,self");
+ $p->parse_file(shift || die) || die $!;
+ print "\n";
+
+More examples are found in the F<eg/> directory of the C<HTML-Parser>
+distribution: the program C<hrefsub> shows how you can edit all links
+found in a document; the program C<htextsub> shows how to edit the text only; the
+program C<hstrip> shows how you can strip out certain tags/elements
+and/or attributes; and the program C<htext> show how to obtain the
+plain text, but not any script/style content.
+
+You can browse the F<eg/> directory online from the I<[Browse]> link on
+the http://search.cpan.org/~gaas/HTML-Parser/ page.
+
+=head1 BUGS
+
+The <style> and <script> sections do not end with the first "</", but
+need the complete corresponding end tag. The standard behaviour is
+not really practical.
+
+When the I<strict_comment> option is enabled, we still recognize
+comments where there is something other than whitespace between even
+and odd "--" markers.
+
+Once $p->boolean_attribute_value has been set, there is no way to
+restore the default behaviour.
+
+There is currently no way to get both quote characters
+into the same literal argspec.
+
+Empty tags, e.g. "<>" and "</>", are not recognized. SGML allows them
+to repeat the previous start tag or close the previous start tag
+respectively.
+
+NET tags, e.g. "code/.../" are not recognized. This is SGML
+shorthand for "<code>...</code>".
+
+Unclosed start or end tags, e.g. "<tt<b>...</b</tt>" are not
+recognized.

+
+=item Parse loop not allowed
+
+(F) A handler invoked the parse() or parse_file() method.
+This is not permitted.
+
+=item marked sections not supported
+
+(F) The $p->marked_sections() method was invoked in a HTML::Parser
+module that was compiled without support for marked sections.
+
+=item Unknown boolean attribute (%d)
+
+(F) Something is wrong with the internal logic that set up aliases for
+boolean attributes.
+
+=item Only code or array references allowed as handler
+
+(F) The second argument for $p->handler must be either a subroutine
+reference, then name of a subroutine or method, or a reference to an
+array.
+
+=item No handler for %s events
+
+(F) The first argument to $p->handler must be a valid event name; i.e. one
+of "start", "end", "text", "process", "declaration" or "comment".
+
+=item Unrecognized identifier %s in argspec
+
+(F) The identifier is not a known argspec name.
+Use one of the names mentioned in the argspec section above.
+
+=item Literal string is longer than 255 chars in argspec
+
+(F) The current implementation limits the length of literals in
+an argspec to 255 characters. Make the literal shorter.
+
+=item Backslash reserved for literal string in argspec
+
+(F) The backslash character "\" is not allowed in argspec literals.
+It is reserved to permit quoting inside a literal in a later version.
+
+=item Unterminated literal string in argspec
+
+(F) The terminating quote character for a literal was not found.
+
+=item Bad argspec (%s)
+
+(F) Only identifier names, literals, spaces and commas
+are allowed in argspecs.
+
+=item Missing comma separator in argspec
+
+(F) Identifiers in an argspec must be separated with ",".
+
+=item Parsing of undecoded UTF-8 will give garbage when decoding entities
+
+(W) The first chunk parsed appears to contain undecoded UTF-8 and one
+or more argspecs that decode entities are used for the callback
+handlers.
+
+The result of decoding will be a mix of encoded and decoded characters
+for any entities that expand to characters with code above 127. This
+is not a good thing.
+
+The solution is to use the Encode::encode_utf8() on the data before
+feeding it to the $p->parse(). For $p->parse_file() pass a file that
+has been opened in ":utf8" mode.
+
+The parser can process raw undecoded UTF-8 sanely if the C<utf8_mode>
+is enabled or if the "attr", "@attr" or "dtext" argspecs is avoided.
+
+=item Parsing string decoded with wrong endianness
+
+(W) The first character in the document is U+FFFE. This is not a
+legal Unicode character but a byte swapped BOM. The result of parsing
+will likely be garbage.
+
+=item Parsing of undecoded UTF-32
+
+(W) The parser found the Unicode UTF-32 BOM signature at the start
+of the document. The result of parsing will likely be garbage.
+
+=item Parsing of undecoded UTF-16
+
+(W) The parser found the Unicode UTF-16 BOM signature at the start of
+the document. The result of parsing will likely be garbage.

+=head1 NAME
+
+HTML::PullParser - Alternative HTML::Parser interface
+
+=head1 SYNOPSIS
+
+ use HTML::PullParser;
+
+ $p = HTML::PullParser->new(file => "index.html",
+ start => 'event, tagname, @attr',
+ end => 'event, tagname',
+ ignore_elements => [qw(script style)],
+ ) || die "Can't open: $!";
+ while (my $token = $p->get_token) {
+ #...do something with $token
+ }
+
+=head1 DESCRIPTION
+
+The HTML::PullParser is an alternative interface to the HTML::Parser class.
+It basically turns the HTML::Parser inside out. You associate a file
+(or any IO::Handle object or string) with the parser at construction time and
+then repeatedly call $parser->get_token to obtain the tags and text
+found in the parsed document.
+
+The following methods are provided:
+
+=over 4
+
+=item $p = HTML::PullParser->new( file => $file, %options )
+
+=item $p = HTML::PullParser->new( doc => \$doc, %options )
+
+A C<HTML::PullParser> can be made to parse from either a file or a
+literal document based on whether the C<file> or C<doc> option is
+passed to the parser's constructor.
+
+The C<file> passed in can either be a file name or a file handle
+object. If a file name is passed, and it can't be opened for reading,
+then the constructor will return an undefined value and $! will tell
+you why it failed. Otherwise the argument is taken to be some object
+that the C<HTML::PullParser> can read() from when it needs more data.
+The stream will be read() until EOF, but not closed.
+
+A C<doc> can be passed plain or as a reference
+to a scalar. If a reference is passed then the value of this scalar
+should not be changed before all tokens have been extracted.
+
+Next the information to be returned for the different token types must
+be set up. This is done by simply associating an argspec (as defined
+in L<HTML::Parser>) with the events you have an interest in. For
+instance, if you want C<start> tokens to be reported as the string
+C<'S'> followed by the tagname and the attributes you might pass an
+C<start>-option like this:
+
+ $p = HTML::PullParser->new(
+ doc => $document_to_parse,
+ start => '"S", tagname, @attr',
+ end => '"E", tagname',
+ );
+
+At last other C<HTML::Parser> options, like C<ignore_tags>, and
+C<unbroken_text>, can be passed in. Note that you should not use the
+I<event>_h options to set up parser handlers. That would confuse the
+inner logic of C<HTML::PullParser>.
+
+=item $token = $p->get_token
+
+This method will return the next I<token> found in the HTML document,
+or C<undef> at the end of the document. The token is returned as an
+array reference. The content of this array match the argspec set up
+during C<HTML::PullParser> construction.
+
+=item $p->unget_token( @tokens )
+
+If you find out you have read too many tokens you can push them back,
+so that they are returned again the next time $p->get_token is called.
+
+=back
+
+=head1 EXAMPLES
+
+The 'eg/hform' script shows how we might parse the form section of
+HTML::Documents using HTML::PullParser.

+
+=head1 SYNOPSIS
+
+ use HTML::Tagset;
+ # Then use any of the items in the HTML::Tagset package
+ # as need arises
+
+=head1 DESCRIPTION
+
+This module contains several data tables useful in various kinds of
+HTML parsing operations.
+
+Note that all tag names used are lowercase.
+
+In the following documentation, a "hashset" is a hash being used as a
+set -- the hash conveys that its keys are there, and the actual values
+associated with the keys are not significant. (But what values are
+there, are always true.)
+

+);
+
+=head1 VARIABLES
+
+Note that none of these variables are exported.
+
+=head2 hashset %HTML::Tagset::emptyElement
+
+This hashset has as values the tag-names (GIs) of elements that cannot
+have content. (For example, "base", "br", "hr".) So
+C<$HTML::Tagset::emptyElement{'hr'}> exists and is true.
+C<$HTML::Tagset::emptyElement{'dl'}> does not exist, and so is not true.

+ embed bgsound spacer
+ basefont col frame
+ ~comment ~literal
+ ~declaration ~pi
+ );
+# The "~"-initial names are for pseudo-elements used by HTML::Entities
+# and TreeBuilder
+
+=head2 hashset %HTML::Tagset::optionalEndTag
+
+This hashset lists tag-names for elements that can have content, but whose
+end-tags are generally, "safely", omissible. Example:
+C<$HTML::Tagset::emptyElement{'li'}> exists and is true.
+
+=cut
+
+%optionalEndTag = map {; $_ => 1 } qw(p li dt dd); # option th tr td);
+
+=head2 hash %HTML::Tagset::linkElements
+
+Values in this hash are tagnames for elements that might contain
+links, and the value for each is a reference to an array of the names
+of attributes whose values can be links.
+

+
+This hash (not hashset) lists what attributes of what elements can be
+printed without showing the value (for example, the "noshade" attribute
+of "hr" elements). For elements with only one such attribute, its value
+is simply that attribute name. For elements with many such attributes,
+the value is a reference to a hashset containing all such attributes.

+=head2 array @HTML::Tagset::p_closure_barriers
+
+This array has a meaning that I have only seen a need for in
+C<HTML::TreeBuilder>, but I include it here on the off chance that someone
+might find it of use:
+
+When we see a "E<lt>pE<gt>" token, we go lookup up the lineage for a p
+element we might have to minimize. At first sight, we might say that
+if there's a p anywhere in the lineage of this new p, it should be
+closed. But that's wrong. Consider this document:
+
+ <html>
+ <head>
+ <title>foo</title>
+ </head>
+ <body>
+ <p>foo
+ <table>
+ <tr>
+ <td>
+ foo
+ <p>bar
+ </td>
+ </tr>
+ </table>
+ </p>
+ </body>
+ </html>
+
+The second p is quite legally inside a much higher p.
+
+My formalization of the reason why this is legal, but this:
+
+ <p>foo<p>bar</p></p>
+
+isn't, is that something about the table constitutes a "barrier" to
+the application of the rule about what p must minimize.
+
+So C<@HTML::Tagset::p_closure_barriers> is the list of all such
+barrier-tags.
+
+=cut
+
+@p_closure_barriers = qw(
+ li blockquote
+ ul ol menu dir
+ dl dt dd
+ td th tr table caption
+ div
+ );
+
+# In an ideal world (i.e., XHTML) we wouldn't have to bother with any of this
+# monkey business of barriers to minimization!
+
+=head2 hashset %isCDATA_Parent
+
+This hashset includes all elements whose content is CDATA.
+
+=cut
+
+%isCDATA_Parent = map {; $_ => 1 }
+ qw(script style xmp listing plaintext);
+
+# TODO: there's nothing else that takes CDATA children, right?
+
+# As the HTML3 DTD (Raggett 1995-04-24) noted:
+# The XMP, LISTING and PLAINTEXT tags are incompatible with SGML
+# and derive from very early versions of HTML. They require non-
+# standard parsers and will cause problems for processing
+# documents with standard SGML tools.
+
+
+=head1 CAVEATS
+
+You may find it useful to alter the behavior of modules (like
+C<HTML::Element> or C<HTML::TreeBuilder>) that use C<HTML::Tagset>'s
+data tables by altering the data tables themselves. You are welcome
+to try, but be careful; and be aware that different modules may or may
+react differently to the data tables being changed.
+
+Note that it may be inappropriate to use these tables for I<producing>
+HTML -- for example, C<%isHeadOrBodyElement> lists the tagnames
+for all elements that can appear either in the head or in the body,
+such as "script". That doesn't mean that I am saying your code that
+produces HTML should feel free to put script elements in either place!
+If you are producing programs that spit out HTML, you should be
+I<intimately> familiar with the DTDs for HTML or XHTML (available at
+C<http://www.w3.org/>), and you should slavishly obey them, not
+the data tables in this document.

+=head1 NAME
+
+HTML::TokeParser - Alternative HTML::Parser interface
+
+=head1 SYNOPSIS
+
+ require HTML::TokeParser;
+ $p = HTML::TokeParser->new("index.html") ||
+ die "Can't open: $!";
+ $p->empty_element_tags(1); # configure its behaviour
+
+ while (my $token = $p->get_token) {
+ #...
+ }
+
+=head1 DESCRIPTION
+
+The C<HTML::TokeParser> is an alternative interface to the
+C<HTML::Parser> class. It is an C<HTML::PullParser> subclass with a
+predeclared set of token types. If you wish the tokens to be reported
+differently you probably want to use the C<HTML::PullParser> directly.
+
+The following methods are available:
+
+=over 4
+
+=item $p = HTML::TokeParser->new( $filename, %opt );
+
+=item $p = HTML::TokeParser->new( $filehandle, %opt );
+
+=item $p = HTML::TokeParser->new( \$document, %opt );
+
+The object constructor argument is either a file name, a file handle
+object, or the complete document to be parsed. Extra options can be
+provided as key/value pairs and are processed as documented by the base
+classes.
+
+If the argument is a plain scalar, then it is taken as the name of a
+file to be opened and parsed. If the file can't be opened for
+reading, then the constructor will return C<undef> and $! will tell
+you why it failed.
+
+If the argument is a reference to a plain scalar, then this scalar is
+taken to be the literal document to parse. The value of this
+scalar should not be changed before all tokens have been extracted.
+
+Otherwise the argument is taken to be some object that the
+C<HTML::TokeParser> can read() from when it needs more data. Typically
+it will be a filehandle of some kind. The stream will be read() until
+EOF, but not closed.
+
+A newly constructed C<HTML::TokeParser> differ from its base classes
+by having the C<unbroken_text> attribute enabled by default. See
+L<HTML::Parser> for a description of this and other attributes that
+influence how the document is parsed. It is often a good idea to enable
+C<empty_element_tags> behaviour.
+
+Note that the parsing result will likely not be valid if raw undecoded
+UTF-8 is used as a source. When parsing UTF-8 encoded files turn
+on UTF-8 decoding:
+
+ open(my $fh, "<:utf8", "index.html") || die "Can't open 'index.html': $!";
+ my $p = HTML::TokeParser->new( $fh );
+ # ...
+
+If a $filename is passed to the constructor the file will be opened in
+raw mode and the parsing result will only be valid if its content is
+Latin-1 or pure ASCII.
+
+If parsing from an UTF-8 encoded string buffer decode it first:
+
+ utf8::decode($document);
+ my $p = HTML::TokeParser->new( \$document );
+ # ...
+
+=item $p->get_token
+
+This method will return the next I<token> found in the HTML document,
+or C<undef> at the end of the document. The token is returned as an
+array reference. The first element of the array will be a string
+denoting the type of this token: "S" for start tag, "E" for end tag,
+"T" for text, "C" for comment, "D" for declaration, and "PI" for
+process instructions. The rest of the token array depend on the type
+like this:
+
+ ["S", $tag, $attr, $attrseq, $text]
+ ["E", $tag, $text]
+ ["T", $text, $is_data]
+ ["C", $text]
+ ["D", $text]
+ ["PI", $token0, $text]
+
+where $attr is a hash reference, $attrseq is an array reference and
+the rest are plain scalars. The L<HTML::Parser/Argspec> explains the
+details.
+
+=item $p->unget_token( @tokens )
+
+If you find you have read too many tokens you can push them back,
+so that they are returned the next time $p->get_token is called.
+
+=item $p->get_tag
+
+=item $p->get_tag( @tags )
+
+This method returns the next start or end tag (skipping any other
+tokens), or C<undef> if there are no more tags in the document. If
+one or more arguments are given, then we skip tokens until one of the
+specified tag types is found. For example:
+
+ $p->get_tag("font", "/font");
+
+will find the next start or end tag for a font-element.
+
+The tag information is returned as an array reference in the same form
+as for $p->get_token above, but the type code (first element) is
+missing. A start tag will be returned like this:
+
+ [$tag, $attr, $attrseq, $text]
+
+The tagname of end tags are prefixed with "/", i.e. end tag is
+returned like this:
+
+ ["/$tag", $text]
+
+=item $p->get_text
+
+=item $p->get_text( @endtags )
+
+This method returns all text found at the current position. It will
+return a zero length string if the next token is not text. Any
+entities will be converted to their corresponding character.
+
+If one or more arguments are given, then we return all text occurring
+before the first of the specified tags found. For example:
+
+ $p->get_text("p", "br");
+
+will return the text up to either a paragraph of linebreak element.
+
+The text might span tags that should be I<textified>. This is
+controlled by the $p->{textify} attribute, which is a hash that
+defines how certain tags can be treated as text. If the name of a
+start tag matches a key in this hash then this tag is converted to
+text. The hash value is used to specify which tag attribute to obtain
+the text from. If this tag attribute is missing, then the upper case
+name of the tag enclosed in brackets is returned, e.g. "[IMG]". The
+hash value can also be a subroutine reference. In this case the
+routine is called with the start tag token content as its argument and
+the return value is treated as the text.
+
+The default $p->{textify} value is:
+
+ {img => "alt", applet => "alt"}
+
+This means that <IMG> and <APPLET> tags are treated as text, and that
+the text to substitute can be found in the ALT attribute.
+
+=item $p->get_trimmed_text
+
+=item $p->get_trimmed_text( @endtags )
+
+Same as $p->get_text above, but will collapse any sequences of white
+space to a single space character. Leading and trailing white space is
+removed.
+
+=item $p->get_phrase
+
+This will return all text found at the current position ignoring any
+phrasal-level tags. Text is extracted until the first non
+phrasal-level tag. Textification of tags is the same as for
+get_text(). This method will collapse white space in the same way as
+get_trimmed_text() does.
+
+The definition of <i>phrasal-level tags</i> is obtained from the
+HTML::Tagset module.
+
+=back
+
+=head1 EXAMPLES
+
+This example extracts all links from a document. It will print one
+line for each link, containing the URL and the textual description
+between the <A>...</A> tags:
+
+ use HTML::TokeParser;
+ $p = HTML::TokeParser->new(shift||"index.html");
+
+ while (my $token = $p->get_tag("a")) {
+ my $url = $token->[1]{href} || "-";
+ my $text = $p->get_trimmed_text("/a");
+ print "$url\t$text\n";
+ }
+
+This example extract the <TITLE> from the document:
+
+ use HTML::TokeParser;
+ $p = HTML::TokeParser->new(shift||"index.html");
+ if ($p->get_tag("title")) {
+ my $title = $p->get_trimmed_text;
+ print "Title: $title\n";
+ }

+=head1 NAME
+
+HTTP::Config - Configuration for request and response objects
+
+=head1 SYNOPSIS
+
+ use HTTP::Config;
+ my $c = HTTP::Config->new;
+ $c->add(m_domain => ".example.com", m_scheme => "http", verbose => 1);
+
+ use HTTP::Request;
+ my $request = HTTP::Request->new(GET => "http://www.example.com");
+
+ if (my @m = $c->matching($request)) {
+ print "Yadayada\n" if $m[0]->{verbose};
+ }
+
+=head1 DESCRIPTION
+
+An C<HTTP::Config> object is a list of entries that
+can be matched against request or request/response pairs. Its
+purpose is to hold configuration data that can be looked up given a
+request or response object.
+
+Each configuration entry is a hash. Some keys specify matching to
+occur against attributes of request/response objects. Other keys can
+be used to hold user data.
+
+The following methods are provided:
+
+=over 4
+
+=item $conf = HTTP::Config->new
+
+Constructs a new empty C<HTTP::Config> object and returns it.
+
+=item $conf->entries
+
+Returns the list of entries in the configuration object.
+In scalar context returns the number of entries.
+
+=item $conf->empty
+
+Return true if there are no entries in the configuration object.
+This is just a shorthand for C<< not $conf->entries >>.
+
+=item $conf->add( %matchspec, %other )
+
+=item $conf->add( \%entry )
+
+Adds a new entry to the configuration.
+You can either pass separate key/value pairs or a hash reference.
+
+=item $conf->remove( %spec )
+
+Removes (and returns) the entries that have matches for all the key/value pairs in %spec.
+If %spec is empty this will match all entries; so it will empty the configuation object.
+
+=item $conf->matching( $uri, $request, $response )
+
+=item $conf->matching( $uri )
+
+=item $conf->matching( $request )
+
+=item $conf->matching( $response )
+
+Returns the entries that match the given $uri, $request and $response triplet.
+
+If called with a single $request object then the $uri is obtained by calling its 'uri_canonical' method.
+If called with a single $response object, then the request object is obtained by calling its 'request' method;
+and then the $uri is obtained as if a single $request was provided.
+
+The entries are returned with the most specific matches first.
+In scalar context returns the most specific match or C<undef> in none match.
+
+=item $conf->add_item( $item, %matchspec )
+
+=item $conf->remove_items( %spec )
+
+=item $conf->matching_items( $uri, $request, $response )
+
+Wrappers that hides the entries themselves.
+
+=back
+
+=head2 Matching
+
+The following keys on a configuration entry specify matching. For all
+of these you can provide an array of values instead of a single value.
+The entry matches if at least one of the values in the array matches.
+
+Entries that require match against a response object attribute will never match
+unless a response object was provided.
+
+=over
+
+=item m_scheme => $scheme
+
+Matches if the URI uses the specified scheme; e.g. "http".
+
+=item m_secure => $bool
+
+If $bool is TRUE; matches if the URI uses a secure scheme. If $bool
+is FALSE; matches if the URI does not use a secure scheme. An example
+of a secure scheme is "https".
+
+=item m_host_port => "$hostname:$port"
+
+Matches if the URI's host_port method return the specified value.
+
+=item m_host => $hostname
+
+Matches if the URI's host method returns the specified value.
+
+=item m_port => $port
+
+Matches if the URI's port method returns the specified value.
+
+=item m_domain => ".$domain"
+
+Matches if the URI's host method return a value that within the given
+domain. The hostname "www.example.com" will for instance match the
+domain ".com".
+
+=item m_path => $path
+
+Matches if the URI's path method returns the specified value.
+
+=item m_path_prefix => $path
+
+Matches if the URI's path is the specified path or has the specified
+path as prefix.
+
+=item m_path_match => $Regexp
+
+Matches if the regular expression matches the URI's path. Eg. qr/\.html$/.
+
+=item m_method => $method
+
+Matches if the request method matches the specified value. Eg. "GET" or "POST".
+
+=item m_code => $digit
+
+=item m_code => $status_code
+
+Matches if the response status code matches. If a single digit is
+specified; matches for all response status codes beginning with that digit.
+
+=item m_proxy => $url
+
+Matches if the request is to be sent to the given Proxy server.
+
+=item m_media_type => "*/*"
+
+=item m_media_type => "text/*"
+
+=item m_media_type => "html"
+
+=item m_media_type => "xhtml"
+
+=item m_media_type => "text/html"
+
+Matches if the response media type matches.
+
+With a value of "html" matches if $response->content_is_html returns TRUE.
+With a value of "xhtml" matches if $response->content_is_xhtml returns TRUE.
+
+=item m_uri__I<$method> => undef
+
+Matches if the URI object provides the method.
+
+=item m_uri__I<$method> => $string
+

+=head1 NAME
+
+HTTP::Cookies - HTTP cookie jars
+
+=head1 SYNOPSIS
+
+ use HTTP::Cookies;
+ $cookie_jar = HTTP::Cookies->new(
+ file => "$ENV{'HOME'}/lwp_cookies.dat",
+ autosave => 1,
+ );
+
+ use LWP;
+ my $browser = LWP::UserAgent->new;
+ $browser->cookie_jar($cookie_jar);
+
+Or for an empty and temporary cookie jar:
+
+ use LWP;
+ my $browser = LWP::UserAgent->new;
+ $browser->cookie_jar( {} );
+
+=head1 DESCRIPTION
+
+This class is for objects that represent a "cookie jar" -- that is, a
+database of all the HTTP cookies that a given LWP::UserAgent object
+knows about.
+
+Cookies are a general mechanism which server side connections can use
+to both store and retrieve information on the client side of the
+connection. For more information about cookies refer to
+<URL:http://curl.haxx.se/rfc/cookie_spec.html> and
+<URL:http://www.cookiecentral.com/>. This module also implements the
+new style cookies described in I<RFC 2965>.
+The two variants of cookies are supposed to be able to coexist happily.
+
+Instances of the class I<HTTP::Cookies> are able to store a collection
+of Set-Cookie2: and Set-Cookie: headers and are able to use this
+information to initialize Cookie-headers in I<HTTP::Request> objects.
+The state of a I<HTTP::Cookies> object can be saved in and restored from
+files.
+
+=head1 METHODS
+
+The following methods are provided:
+
+=over 4
+
+=item $cookie_jar = HTTP::Cookies->new
+
+The constructor takes hash style parameters. The following
+parameters are recognized:
+
+ file: name of the file to restore cookies from and save cookies to
+ autosave: save during destruction (bool)
+ ignore_discard: save even cookies that are requested to be discarded (bool)
+ hide_cookie2: do not add Cookie2 header to requests
+
+Future parameters might include (not yet implemented):
+
+ max_cookies 300
+ max_cookies_per_domain 20
+ max_cookie_size 4096
+
+ no_cookies list of domain names that we never return cookies to
+
+=item $cookie_jar->add_cookie_header( $request )
+
+The add_cookie_header() method will set the appropriate Cookie:-header
+for the I<HTTP::Request> object given as argument. The $request must
+have a valid url attribute before this method is called.
+
+=item $cookie_jar->extract_cookies( $response )
+
+The extract_cookies() method will look for Set-Cookie: and
+Set-Cookie2: headers in the I<HTTP::Response> object passed as
+argument. Any of these headers that are found are used to update
+the state of the $cookie_jar.
+
+=item $cookie_jar->set_cookie( $version, $key, $val, $path, $domain, $port, $path_spec, $secure, $maxage, $discard, \%rest )
+
+The set_cookie() method updates the state of the $cookie_jar. The
+$key, $val, $domain, $port and $path arguments are strings. The
+$path_spec, $secure, $discard arguments are boolean values. The $maxage
+value is a number indicating number of seconds that this cookie will
+live. A value <= 0 will delete this cookie. %rest defines
+various other attributes like "Comment" and "CommentURL".
+
+=item $cookie_jar->save
+
+=item $cookie_jar->save( $file )
+
+This method file saves the state of the $cookie_jar to a file.
+The state can then be restored later using the load() method. If a
+filename is not specified we will use the name specified during
+construction. If the attribute I<ignore_discard> is set, then we
+will even save cookies that are marked to be discarded.
+
+The default is to save a sequence of "Set-Cookie3" lines.
+"Set-Cookie3" is a proprietary LWP format, not known to be compatible
+with any browser. The I<HTTP::Cookies::Netscape> sub-class can
+be used to save in a format compatible with Netscape.
+
+=item $cookie_jar->load
+
+=item $cookie_jar->load( $file )
+
+This method reads the cookies from the file and adds them to the
+$cookie_jar. The file must be in the format written by the save()
+method.
+
+=item $cookie_jar->revert
+
+This method empties the $cookie_jar and re-loads the $cookie_jar
+from the last save file.
+
+=item $cookie_jar->clear
+
+=item $cookie_jar->clear( $domain )
+
+=item $cookie_jar->clear( $domain, $path )
+
+=item $cookie_jar->clear( $domain, $path, $key )
+
+Invoking this method without arguments will empty the whole
+$cookie_jar. If given a single argument only cookies belonging to
+that domain will be removed. If given two arguments, cookies
+belonging to the specified path within that domain are removed. If
+given three arguments, then the cookie with the specified key, path
+and domain is removed.
+
+=item $cookie_jar->clear_temporary_cookies
+
+Discard all temporary cookies. Scans for all cookies in the jar
+with either no expire field or a true C<discard> flag. To be
+called when the user agent shuts down according to RFC 2965.
+
+=item $cookie_jar->scan( \&callback )
+
+The argument is a subroutine that will be invoked for each cookie
+stored in the $cookie_jar. The subroutine will be invoked with
+the following arguments:
+
+ 0 version
+ 1 key
+ 2 val
+ 3 path
+ 4 domain
+ 5 port
+ 6 path_spec
+ 7 secure
+ 8 expires
+ 9 discard
+ 10 hash
+
+=item $cookie_jar->as_string
+
+=item $cookie_jar->as_string( $skip_discardables )
+
+The as_string() method will return the state of the $cookie_jar
+represented as a sequence of "Set-Cookie3" header lines separated by
+"\n". If $skip_discardables is TRUE, it will not return lines for
+cookies with the I<Discard> attribute.

+=head1 NAME
+
+HTTP::Cookies::Microsoft - access to Microsoft cookies files
+
+=head1 SYNOPSIS
+
+ use LWP;
+ use HTTP::Cookies::Microsoft;
+ use Win32::TieRegistry(Delimiter => "/");
+ my $cookies_dir = $Registry->
+ {"CUser/Software/Microsoft/Windows/CurrentVersion/Explorer/Shell Folders/Cookies"};
+
+ $cookie_jar = HTTP::Cookies::Microsoft->new(
+ file => "$cookies_dir\\index.dat",
+ 'delayload' => 1,
+ );
+ my $browser = LWP::UserAgent->new;
+ $browser->cookie_jar( $cookie_jar );
+
+=head1 DESCRIPTION
+
+This is a subclass of C<HTTP::Cookies> which
+loads Microsoft Internet Explorer 5.x and 6.x for Windows (MSIE)
+cookie files.
+
+See the documentation for L<HTTP::Cookies>.
+
+=head1 METHODS
+
+The following methods are provided:
+
+=over 4
+
+=item $cookie_jar = HTTP::Cookies::Microsoft->new;
+
+The constructor takes hash style parameters. In addition
+to the regular HTTP::Cookies parameters, HTTP::Cookies::Microsoft
+recognizes the following:
+
+ delayload: delay loading of cookie data until a request
+ is actually made. This results in faster
+ runtime unless you use most of the cookies
+ since only the domain's cookie data
+ is loaded on demand.
+
+=back
+
+=head1 CAVEATS
+
+Please note that the code DOESN'T support saving to the MSIE
+cookie file format.

+=head1 NAME
+

+=head1 SYNOPSIS
+
+ use LWP;

+ );

+
+=head1 DESCRIPTION
+
+This is a subclass of C<HTTP::Cookies> that reads (and optionally
+writes) Netscape/Mozilla cookie files.
+
+See the documentation for L<HTTP::Cookies>.
+
+=head1 CAVEATS
+
+Please note that the Netscape/Mozilla cookie file format can't store
+all the information available in the Set-Cookie2 headers, so you will
+probably lose some information if you save in this format.
+
+At time of writing, this module seems to work fine with Mozilla
+Phoenix/Firebird.

+
+=head1 DESCRIPTION
+
+Instances of the C<HTTP::Daemon> class are HTTP/1.1 servers that
+listen on a socket for incoming requests. The C<HTTP::Daemon> is a
+subclass of C<IO::Socket::INET>, so you can perform socket operations
+directly on it too.
+
+The accept() method will return when a connection from a client is
+available. The returned value will be an C<HTTP::Daemon::ClientConn>
+object which is another C<IO::Socket::INET> subclass. Calling the
+get_request() method on this object will read data from the client and
+return an C<HTTP::Request> object. The ClientConn object also provide
+methods to send back various responses.
+
+This HTTP daemon does not fork(2) for you. Your application, i.e. the
+user of the C<HTTP::Daemon> is responsible for forking if that is
+desirable. Also note that the user is responsible for generating
+responses that conform to the HTTP/1.1 protocol.
+
+The following methods of C<HTTP::Daemon> are new (or enhanced) relative
+to the C<IO::Socket::INET> base class:
+
+=over 4
+
+=item $d = HTTP::Daemon->new
+
+=item $d = HTTP::Daemon->new( %opts )
+
+The constructor method takes the same arguments as the
+C<IO::Socket::INET> constructor, but unlike its base class it can also
+be called without any arguments. The daemon will then set up a listen
+queue of 5 connections and allocate some random port number.
+
+A server that wants to bind to some specific address on the standard
+HTTP port will be constructed like this:
+
+ $d = HTTP::Daemon->new(
+ LocalAddr => 'www.thisplace.com',
+ LocalPort => 80,
+ );
+
+See L<IO::Socket::INET> for a description of other arguments that can
+be used configure the daemon during construction.
+
+=item $c = $d->accept
+
+=item $c = $d->accept( $pkg )
+
+=item ($c, $peer_addr) = $d->accept
+
+This method works the same the one provided by the base class, but it
+returns an C<HTTP::Daemon::ClientConn> reference by default. If a
+package name is provided as argument, then the returned object will be
+blessed into the given class. It is probably a good idea to make that
+class a subclass of C<HTTP::Daemon::ClientConn>.
+
+The accept method will return C<undef> if timeouts have been enabled
+and no connection is made within the given time. The timeout() method
+is described in L<IO::Socket>.
+
+In list context both the client object and the peer address will be
+returned; see the description of the accept method L<IO::Socket> for
+details.
+
+=item $d->url
+
+Returns a URL string that can be used to access the server root.
+
+=item $d->product_tokens
+
+Returns the name that this server will use to identify itself. This
+is the string that is sent with the C<Server> response header. The
+main reason to have this method is that subclasses can override it if
+they want to use another product name.
+
+The default is the string "libwww-perl-daemon/#.##" where "#.##" is
+replaced with the version number of this module.
+
+=back
+
+The C<HTTP::Daemon::ClientConn> is a C<IO::Socket::INET>
+subclass. Instances of this class are returned by the accept() method
+of C<HTTP::Daemon>. The following methods are provided:
+
+=over 4
+
+=item $c->get_request
+
+=item $c->get_request( $headers_only )
+
+This method reads data from the client and turns it into an
+C<HTTP::Request> object which is returned. It returns C<undef>
+if reading fails. If it fails, then the C<HTTP::Daemon::ClientConn>
+object ($c) should be discarded, and you should not try call this
+method again on it. The $c->reason method might give you some
+information about why $c->get_request failed.
+
+The get_request() method will normally not return until the whole
+request has been received from the client. This might not be what you
+want if the request is an upload of a large file (and with chunked
+transfer encoding HTTP can even support infinite request messages -
+uploading live audio for instance). If you pass a TRUE value as the
+$headers_only argument, then get_request() will return immediately
+after parsing the request headers and you are responsible for reading
+the rest of the request content. If you are going to call
+$c->get_request again on the same connection you better read the
+correct number of bytes.
+
+=item $c->read_buffer
+
+=item $c->read_buffer( $new_value )
+
+Bytes read by $c->get_request, but not used are placed in the I<read
+buffer>. The next time $c->get_request is called it will consume the
+bytes in this buffer before reading more data from the network
+connection itself. The read buffer is invalid after $c->get_request
+has failed.
+
+If you handle the reading of the request content yourself you need to
+empty this buffer before you read more and you need to place
+unconsumed bytes here. You also need this buffer if you implement
+services like I<101 Switching Protocols>.
+
+This method always returns the old buffer content and can optionally
+replace the buffer content if you pass it an argument.
+
+=item $c->reason
+
+When $c->get_request returns C<undef> you can obtain a short string
+describing why it happened by calling $c->reason.
+
+=item $c->proto_ge( $proto )
+
+Return TRUE if the client announced a protocol with version number
+greater or equal to the given argument. The $proto argument can be a
+string like "HTTP/1.1" or just "1.1".
+
+=item $c->antique_client
+
+Return TRUE if the client speaks the HTTP/0.9 protocol. No status
+code and no headers should be returned to such a client. This should
+be the same as !$c->proto_ge("HTTP/1.0").
+
+=item $c->head_request
+
+Return TRUE if the last request was a C<HEAD> request. No content
+body must be generated for these requests.
+
+=item $c->force_last_request
+
+Make sure that $c->get_request will not try to read more requests off
+this connection. If you generate a response that is not self
+delimiting, then you should signal this fact by calling this method.
+
+This attribute is turned on automatically if the client announces
+protocol HTTP/1.0 or worse and does not include a "Connection:
+Keep-Alive" header. It is also turned on automatically when HTTP/1.1
+or better clients send the "Connection: close" request header.
+
+=item $c->send_status_line
+
+=item $c->send_status_line( $code )
+
+=item $c->send_status_line( $code, $mess )
+
+=item $c->send_status_line( $code, $mess, $proto )
+
+Send the status line back to the client. If $code is omitted 200 is
+assumed. If $mess is omitted, then a message corresponding to $code
+is inserted. If $proto is missing the content of the
+$HTTP::Daemon::PROTO variable is used.
+
+=item $c->send_crlf
+
+Send the CRLF sequence to the client.
+
+=item $c->send_basic_header
+
+=item $c->send_basic_header( $code )
+
+=item $c->send_basic_header( $code, $mess )
+
+=item $c->send_basic_header( $code, $mess, $proto )
+
+Send the status line and the "Date:" and "Server:" headers back to
+the client. This header is assumed to be continued and does not end
+with an empty CRLF line.
+
+See the description of send_status_line() for the description of the
+accepted arguments.
+
+=item $c->send_header( $field, $value )
+
+=item $c->send_header( $field1, $value1, $field2, $value2, ... )
+
+Send one or more header lines.
+
+=item $c->send_response( $res )
+
+Write a C<HTTP::Response> object to the
+client as a response. We try hard to make sure that the response is
+self delimiting so that the connection can stay persistent for further
+request/response exchanges.
+
+The content attribute of the C<HTTP::Response> object can be a normal
+string or a subroutine reference. If it is a subroutine, then
+whatever this callback routine returns is written back to the
+client as the response content. The routine will be called until it
+return an undefined or empty value. If the client is HTTP/1.1 aware
+then we will use chunked transfer encoding for the response.
+
+=item $c->send_redirect( $loc )
+
+=item $c->send_redirect( $loc, $code )
+
+=item $c->send_redirect( $loc, $code, $entity_body )
+
+Send a redirect response back to the client. The location ($loc) can
+be an absolute or relative URL. The $code must be one the redirect
+status codes, and defaults to "301 Moved Permanently"
+
+=item $c->send_error
+
+=item $c->send_error( $code )
+
+=item $c->send_error( $code, $error_message )
+
+Send an error response back to the client. If the $code is missing a
+"Bad Request" error is reported. The $error_message is a string that
+is incorporated in the body of the HTML entity body.
+
+=item $c->send_file_response( $filename )
+
+Send back a response with the specified $filename as content. If the
+file is a directory we try to generate an HTML index of it.
+
+=item $c->send_file( $filename )
+
+=item $c->send_file( $fd )
+
+Copy the file to the client. The file can be a string (which
+will be interpreted as a filename) or a reference to an C<IO::Handle>
+or glob.
+
+=item $c->daemon
+
+Return a reference to the corresponding C<HTTP::Daemon> object.

+HTTP::Date - date conversion routines
+
+=head1 SYNOPSIS
+
+ use HTTP::Date;
+
+ $string = time2str($time); # Format as GMT ASCII time
+ $time = str2time($string); # convert ASCII date to machine time
+
+=head1 DESCRIPTION
+
+This module provides functions that deal the date formats used by the
+HTTP protocol (and then some more). Only the first two functions,
+time2str() and str2time(), are exported by default.
+
+=over 4
+
+=item time2str( [$time] )
+
+The time2str() function converts a machine time (seconds since epoch)
+to a string. If the function is called without an argument or with an
+undefined argument, it will use the current time.
+
+The string returned is in the format preferred for the HTTP protocol.
+This is a fixed length subset of the format defined by RFC 1123,
+represented in Universal Time (GMT). An example of a time stamp
+in this format is:
+
+ Sun, 06 Nov 1994 08:49:37 GMT
+
+=item str2time( $str [, $zone] )
+
+The str2time() function converts a string to machine time. It returns
+C<undef> if the format of $str is unrecognized, otherwise whatever the
+C<Time::Local> functions can make out of the parsed time. Dates
+before the system's epoch may not work on all operating systems. The
+time formats recognized are the same as for parse_date().
+
+The function also takes an optional second argument that specifies the
+default time zone to use when converting the date. This parameter is
+ignored if the zone is found in the date string itself. If this
+parameter is missing, and the date string format does not contain any
+zone specification, then the local time zone is assumed.
+
+If the zone is not "C<GMT>" or numerical (like "C<-0800>" or
+"C<+0100>"), then the C<Time::Zone> module must be installed in order
+to get the date recognized.
+
+=item parse_date( $str )
+
+This function will try to parse a date string, and then return it as a
+list of numerical values followed by a (possible undefined) time zone
+specifier; ($year, $month, $day, $hour, $min, $sec, $tz). The $year
+returned will B<not> have the number 1900 subtracted from it and the
+$month numbers start with 1.
+
+In scalar context the numbers are interpolated in a string of the
+"YYYY-MM-DD hh:mm:ss TZ"-format and returned.
+
+If the date is unrecognized, then the empty list is returned.
+
+The function is able to parse the following formats:
+
+ "Wed, 09 Feb 1994 22:23:32 GMT" -- HTTP format
+ "Thu Feb 3 17:03:55 GMT 1994" -- ctime(3) format
+ "Thu Feb 3 00:00:00 1994", -- ANSI C asctime() format
+ "Tuesday, 08-Feb-94 14:15:29 GMT" -- old rfc850 HTTP format
+ "Tuesday, 08-Feb-1994 14:15:29 GMT" -- broken rfc850 HTTP format
+
+ "03/Feb/1994:17:03:55 -0700" -- common logfile format
+ "09 Feb 1994 22:23:32 GMT" -- HTTP format (no weekday)
+ "08-Feb-94 14:15:29 GMT" -- rfc850 format (no weekday)
+ "08-Feb-1994 14:15:29 GMT" -- broken rfc850 format (no weekday)
+
+ "1994-02-03 14:15:29 -0100" -- ISO 8601 format
+ "1994-02-03 14:15:29" -- zone is optional
+ "1994-02-03" -- only date
+ "1994-02-03T14:15:29" -- Use T as separator
+ "19940203T141529Z" -- ISO 8601 compact format
+ "19940203" -- only date
+
+ "08-Feb-94" -- old rfc850 HTTP format (no weekday, no time)
+ "08-Feb-1994" -- broken rfc850 HTTP format (no weekday, no time)
+ "09 Feb 1994" -- proposed new HTTP format (no weekday, no time)
+ "03/Feb/1994" -- common logfile format (no time, no offset)
+
+ "Feb 3 1994" -- Unix 'ls -l' format
+ "Feb 3 17:03" -- Unix 'ls -l' format
+
+ "11-15-96 03:52PM" -- Windows 'dir' format
+
+The parser ignores leading and trailing whitespace. It also allow the
+seconds to be missing and the month to be numerical in most formats.
+
+If the year is missing, then we assume that the date is the first
+matching date I<before> current month. If the year is given with only
+2 digits, then parse_date() will select the century that makes the
+year closest to the current date.
+
+=item time2iso( [$time] )
+
+Same as time2str(), but returns a "YYYY-MM-DD hh:mm:ss"-formatted
+string representing time in the local time zone.
+
+=item time2isoz( [$time] )
+
+Same as time2str(), but returns a "YYYY-MM-DD hh:mm:ssZ"-formatted
+string representing Universal Time.

+HTTP::Headers - Class encapsulating HTTP Message headers
+
+=head1 SYNOPSIS
+
+ require HTTP::Headers;
+ $h = HTTP::Headers->new;
+
+ $h->header('Content-Type' => 'text/plain'); # set
+ $ct = $h->header('Content-Type'); # get
+ $h->remove_header('Content-Type'); # delete
+
+=head1 DESCRIPTION
+
+The C<HTTP::Headers> class encapsulates HTTP-style message headers.
+The headers consist of attribute-value pairs also called fields, which
+may be repeated, and which are printed in a particular order. The
+field names are cases insensitive.
+
+Instances of this class are usually created as member variables of the
+C<HTTP::Request> and C<HTTP::Response> classes, internal to the
+library.
+
+The following methods are available:
+
+=over 4
+
+=item $h = HTTP::Headers->new
+
+Constructs a new C<HTTP::Headers> object. You might pass some initial
+attribute-value pairs as parameters to the constructor. I<E.g.>:
+
+ $h = HTTP::Headers->new(
+ Date => 'Thu, 03 Feb 1994 00:00:00 GMT',
+ Content_Type => 'text/html; version=3.2',
+ Content_Base => 'http://www.perl.org/');
+
+The constructor arguments are passed to the C<header> method which is
+described below.
+
+=item $h->clone
+
+Returns a copy of this C<HTTP::Headers> object.
+
+=item $h->header( $field )
+
+=item $h->header( $field => $value )
+
+=item $h->header( $f1 => $v1, $f2 => $v2, ... )
+
+Get or set the value of one or more header fields. The header field
+name ($field) is not case sensitive. To make the life easier for perl
+users who wants to avoid quoting before the => operator, you can use
+'_' as a replacement for '-' in header names.
+
+The header() method accepts multiple ($field => $value) pairs, which
+means that you can update several fields with a single invocation.
+
+The $value argument may be a plain string or a reference to an array
+of strings for a multi-valued field. If the $value is provided as
+C<undef> then the field is removed. If the $value is not given, then
+that header field will remain unchanged.
+
+The old value (or values) of the last of the header fields is returned.
+If no such field exists C<undef> will be returned.
+
+A multi-valued field will be returned as separate values in list
+context and will be concatenated with ", " as separator in scalar
+context. The HTTP spec (RFC 2616) promise that joining multiple
+values in this way will not change the semantic of a header field, but
+in practice there are cases like old-style Netscape cookies (see
+L<HTTP::Cookies>) where "," is used as part of the syntax of a single
+field value.
+
+Examples:
+
+ $header->header(MIME_Version => '1.0',
+ User_Agent => 'My-Web-Client/0.01');
+ $header->header(Accept => "text/html, text/plain, image/*");
+ $header->header(Accept => [qw(text/html text/plain image/*)]);
+ @accepts = $header->header('Accept'); # get multiple values
+ $accepts = $header->header('Accept'); # get values as a single string
+
+=item $h->push_header( $field => $value )
+
+=item $h->push_header( $f1 => $v1, $f2 => $v2, ... )
+
+Add a new field value for the specified header field. Previous values
+for the same field are retained.
+
+As for the header() method, the field name ($field) is not case
+sensitive and '_' can be used as a replacement for '-'.
+
+The $value argument may be a scalar or a reference to a list of
+scalars.
+
+ $header->push_header(Accept => 'image/jpeg');
+ $header->push_header(Accept => [map "image/$_", qw(gif png tiff)]);
+
+=item $h->init_header( $field => $value )
+
+Set the specified header to the given value, but only if no previous
+value for that field is set.
+
+The header field name ($field) is not case sensitive and '_'
+can be used as a replacement for '-'.
+
+The $value argument may be a scalar or a reference to a list of
+scalars.
+
+=item $h->remove_header( $field, ... )
+
+This function removes the header fields with the specified names.
+
+The header field names ($field) are not case sensitive and '_'
+can be used as a replacement for '-'.
+
+The return value is the values of the fields removed. In scalar
+context the number of fields removed is returned.
+
+Note that if you pass in multiple field names then it is generally not
+possible to tell which of the returned values belonged to which field.
+
+=item $h->remove_content_headers
+
+This will remove all the header fields used to describe the content of
+a message. All header field names prefixed with C<Content-> fall
+into this category, as well as C<Allow>, C<Expires> and
+C<Last-Modified>. RFC 2616 denotes these fields as I<Entity Header
+Fields>.
+
+The return value is a new C<HTTP::Headers> object that contains the
+removed headers only.
+
+=item $h->clear
+
+This will remove all header fields.
+
+=item $h->header_field_names
+
+Returns the list of distinct names for the fields present in the
+header. The field names have case as suggested by HTTP spec, and the
+names are returned in the recommended "Good Practice" order.
+
+In scalar context return the number of distinct field names.
+
+=item $h->scan( \&process_header_field )
+
+Apply a subroutine to each header field in turn. The callback routine
+is called with two parameters; the name of the field and a single
+value (a string). If a header field is multi-valued, then the
+routine is called once for each value. The field name passed to the
+callback routine has case as suggested by HTTP spec, and the headers
+will be visited in the recommended "Good Practice" order.
+
+Any return values of the callback routine are ignored. The loop can
+be broken by raising an exception (C<die>), but the caller of scan()
+would have to trap the exception itself.
+
+=item $h->as_string
+
+=item $h->as_string( $eol )
+
+Return the header fields as a formatted MIME header. Since it
+internally uses the C<scan> method to build the string, the result
+will use case as suggested by HTTP spec, and it will follow
+recommended "Good Practice" of ordering the header fields. Long header
+values are not folded.
+
+The optional $eol parameter specifies the line ending sequence to
+use. The default is "\n". Embedded "\n" characters in header field
+values will be substituted with this line ending sequence.
+
+=back
+
+=head1 CONVENIENCE METHODS
+
+The most frequently used headers can also be accessed through the
+following convenience methods. Most of these methods can both be used to read
+and to set the value of a header. The header value is set if you pass
+an argument to the method. The old header value is always returned.
+If the given header did not exist then C<undef> is returned.
+
+Methods that deal with dates/times always convert their value to system
+time (seconds since Jan 1, 1970) and they also expect this kind of
+value when the header value is set.
+
+=over 4
+
+=item $h->date
+
+This header represents the date and time at which the message was
+originated. I<E.g.>:
+
+ $h->date(time); # set current date
+
+=item $h->expires
+
+This header gives the date and time after which the entity should be
+considered stale.
+
+=item $h->if_modified_since
+
+=item $h->if_unmodified_since
+
+These header fields are used to make a request conditional. If the requested
+resource has (or has not) been modified since the time specified in this field,
+then the server will return a C<304 Not Modified> response instead of
+the document itself.
+
+=item $h->last_modified
+
+This header indicates the date and time at which the resource was last
+modified. I<E.g.>:
+
+ # check if document is more than 1 hour old
+ if (my $last_mod = $h->last_modified) {
+ if ($last_mod < time - 60*60) {
+ ...
+ }
+ }
+
+=item $h->content_type
+
+The Content-Type header field indicates the media type of the message
+content. I<E.g.>:
+
+ $h->content_type('text/html');
+
+The value returned will be converted to lower case, and potential
+parameters will be chopped off and returned as a separate value if in
+an array context. If there is no such header field, then the empty
+string is returned. This makes it safe to do the following:
+
+ if ($h->content_type eq 'text/html') {
+ # we enter this place even if the real header value happens to
+ # be 'TEXT/HTML; version=3.0'
+ ...
+ }
+
+=item $h->content_type_charset
+
+Returns the upper-cased charset specified in the Content-Type header. In list
+context return the lower-cased bare content type followed by the upper-cased
+charset. Both values will be C<undef> if not specified in the header.
+
+=item $h->content_is_text
+
+Returns TRUE if the Content-Type header field indicate that the
+content is textual.
+
+=item $h->content_is_html
+
+Returns TRUE if the Content-Type header field indicate that the
+content is some kind of HTML (including XHTML). This method can't be
+used to set Content-Type.
+
+=item $h->content_is_xhtml
+
+Returns TRUE if the Content-Type header field indicate that the
+content is XHTML. This method can't be used to set Content-Type.
+
+=item $h->content_is_xml
+
+Returns TRUE if the Content-Type header field indicate that the
+content is XML. This method can't be used to set Content-Type.
+
+=item $h->content_encoding
+
+The Content-Encoding header field is used as a modifier to the
+media type. When present, its value indicates what additional
+encoding mechanism has been applied to the resource.
+
+=item $h->content_length
+
+A decimal number indicating the size in bytes of the message content.
+
+=item $h->content_language
+
+The natural language(s) of the intended audience for the message
+content. The value is one or more language tags as defined by RFC
+1766. Eg. "no" for some kind of Norwegian and "en-US" for English the
+way it is written in the US.
+
+=item $h->title
+
+The title of the document. In libwww-perl this header will be
+initialized automatically from the E<lt>TITLE>...E<lt>/TITLE> element
+of HTML documents. I<This header is no longer part of the HTTP
+standard.>
+
+=item $h->user_agent
+
+This header field is used in request messages and contains information
+about the user agent originating the request. I<E.g.>:
+
+ $h->user_agent('Mozilla/5.0 (compatible; MSIE 7.0; Windows NT 6.0)');
+
+=item $h->server
+
+The server header field contains information about the software being
+used by the originating server program handling the request.
+
+=item $h->from
+
+This header should contain an Internet e-mail address for the human
+user who controls the requesting user agent. The address should be
+machine-usable, as defined by RFC822. E.g.:
+
+ $h->from('King Kong <king@kong.com>');
+
+I<This header is no longer part of the HTTP standard.>
+
+=item $h->referer
+
+Used to specify the address (URI) of the document from which the
+requested resource address was obtained.
+
+The "Free On-line Dictionary of Computing" as this to say about the
+word I<referer>:
+
+ <World-Wide Web> A misspelling of "referrer" which
+ somehow made it into the {HTTP} standard. A given {web
+ page}'s referer (sic) is the {URL} of whatever web page
+ contains the link that the user followed to the current
+ page. Most browsers pass this information as part of a
+ request.
+
+ (1998-10-19)
+
+By popular demand C<referrer> exists as an alias for this method so you
+can avoid this misspelling in your programs and still send the right
+thing on the wire.
+
+When setting the referrer, this method removes the fragment from the
+given URI if it is present, as mandated by RFC2616. Note that
+the removal does I<not> happen automatically if using the header(),
+push_header() or init_header() methods to set the referrer.
+
+=item $h->www_authenticate
+
+This header must be included as part of a C<401 Unauthorized> response.
+The field value consist of a challenge that indicates the
+authentication scheme and parameters applicable to the requested URI.
+
+=item $h->proxy_authenticate
+
+This header must be included in a C<407 Proxy Authentication Required>
+response.
+
+=item $h->authorization
+
+=item $h->proxy_authorization
+
+A user agent that wishes to authenticate itself with a server or a
+proxy, may do so by including these headers.
+
+=item $h->authorization_basic
+
+This method is used to get or set an authorization header that use the
+"Basic Authentication Scheme". In array context it will return two
+values; the user name and the password. In scalar context it will
+return I<"uname:password"> as a single string value.
+
+When used to set the header value, it expects two arguments. I<E.g.>:
+
+ $h->authorization_basic($uname, $password);
+
+The method will croak if the $uname contains a colon ':'.
+
+=item $h->proxy_authorization_basic
+
+Same as authorization_basic() but will set the "Proxy-Authorization"
+header instead.
+
+=back
+
+=head1 NON-CANONICALIZED FIELD NAMES
+
+The header field name spelling is normally canonicalized including the
+'_' to '-' translation. There are some application where this is not
+appropriate. Prefixing field names with ':' allow you to force a
+specific spelling. For example if you really want a header field name
+to show up as C<foo_bar> instead of "Foo-Bar", you might set it like
+this:
+
+ $h->header(":foo_bar" => 1);
+
+These field names are returned with the ':' intact for
+$h->header_field_names and the $h->scan callback, but the colons do
+not show in $h->as_string.

+=head1 NAME
+
+HTTP::Headers::Util - Header value parsing utility functions
+
+=head1 SYNOPSIS
+
+ use HTTP::Headers::Util qw(split_header_words);
+ @values = split_header_words($h->header("Content-Type"));
+
+=head1 DESCRIPTION
+
+This module provides a few functions that helps parsing and
+construction of valid HTTP header values. None of the functions are
+exported by default.
+
+The following functions are available:
+
+=over 4
+
+
+=item split_header_words( @header_values )
+
+This function will parse the header values given as argument into a
+list of anonymous arrays containing key/value pairs. The function
+knows how to deal with ",", ";" and "=" as well as quoted values after
+"=". A list of space separated tokens are parsed as if they were
+separated by ";".
+
+If the @header_values passed as argument contains multiple values,
+then they are treated as if they were a single value separated by
+comma ",".
+
+This means that this function is useful for parsing header fields that
+follow this syntax (BNF as from the HTTP/1.1 specification, but we relax
+the requirement for tokens).
+
+ headers = #header
+ header = (token | parameter) *( [";"] (token | parameter))
+
+ token = 1*<any CHAR except CTLs or separators>
+ separators = "(" | ")" | "<" | ">" | "@"
+ | "," | ";" | ":" | "\" | <">
+ | "/" | "[" | "]" | "?" | "="
+ | "{" | "}" | SP | HT
+
+ quoted-string = ( <"> *(qdtext | quoted-pair ) <"> )
+ qdtext = <any TEXT except <">>
+ quoted-pair = "\" CHAR
+
+ parameter = attribute "=" value
+ attribute = token
+ value = token | quoted-string
+
+Each I<header> is represented by an anonymous array of key/value
+pairs. The keys will be all be forced to lower case.
+The value for a simple token (not part of a parameter) is C<undef>.
+Syntactically incorrect headers will not necessary be parsed as you
+would want.
+
+This is easier to describe with some examples:
+
+ split_header_words('foo="bar"; port="80,81"; DISCARD, BAR=baz');
+ split_header_words('text/html; charset="iso-8859-1"');
+ split_header_words('Basic realm="\\"foo\\\\bar\\""');
+
+will return
+
+ [foo=>'bar', port=>'80,81', discard=> undef], [bar=>'baz' ]
+ ['text/html' => undef, charset => 'iso-8859-1']
+ [basic => undef, realm => "\"foo\\bar\""]
+
+If you don't want the function to convert tokens and attribute keys to
+lower case you can call it as C<_split_header_words> instead (with a
+leading underscore).
+
+=item join_header_words( @arrays )
+
+This will do the opposite of the conversion done by split_header_words().
+It takes a list of anonymous arrays as arguments (or a list of
+key/value pairs) and produces a single header value. Attribute values
+are quoted if needed.
+
+Example:
+
+ join_header_words(["text/plain" => undef, charset => "iso-8859/1"]);
+ join_header_words("text/plain" => undef, charset => "iso-8859/1");
+
+will both return the string:
+
+ text/plain; charset="iso-8859/1"

+=head1 NAME
+
+HTTP::Message - HTTP style message (base class)
+
+=head1 SYNOPSIS
+
+ use base 'HTTP::Message';
+
+=head1 DESCRIPTION
+
+An C<HTTP::Message> object contains some headers and a content body.
+The following methods are available:
+
+=over 4
+
+=item $mess = HTTP::Message->new
+
+=item $mess = HTTP::Message->new( $headers )
+
+=item $mess = HTTP::Message->new( $headers, $content )
+
+This constructs a new message object. Normally you would want
+construct C<HTTP::Request> or C<HTTP::Response> objects instead.
+
+The optional $header argument should be a reference to an
+C<HTTP::Headers> object or a plain array reference of key/value pairs.
+If an C<HTTP::Headers> object is provided then a copy of it will be
+embedded into the constructed message, i.e. it will not be owned and
+can be modified afterwards without affecting the message.
+
+The optional $content argument should be a string of bytes.
+
+=item $mess = HTTP::Message->parse( $str )
+
+This constructs a new message object by parsing the given string.
+
+=item $mess->headers
+
+Returns the embedded C<HTTP::Headers> object.
+
+=item $mess->headers_as_string
+
+=item $mess->headers_as_string( $eol )
+
+Call the as_string() method for the headers in the
+message. This will be the same as
+
+ $mess->headers->as_string
+
+but it will make your program a whole character shorter :-)
+
+=item $mess->content
+
+=item $mess->content( $bytes )
+
+The content() method sets the raw content if an argument is given. If no
+argument is given the content is not touched. In either case the
+original raw content is returned.
+
+Note that the content should be a string of bytes. Strings in perl
+can contain characters outside the range of a byte. The C<Encode>
+module can be used to turn such strings into a string of bytes.
+
+=item $mess->add_content( $bytes )
+
+The add_content() methods appends more data bytes to the end of the
+current content buffer.
+
+=item $mess->add_content_utf8( $string )
+
+The add_content_utf8() method appends the UTF-8 bytes representing the
+string to the end of the current content buffer.
+
+=item $mess->content_ref
+
+=item $mess->content_ref( \$bytes )
+
+The content_ref() method will return a reference to content buffer string.
+It can be more efficient to access the content this way if the content
+is huge, and it can even be used for direct manipulation of the content,
+for instance:
+
+ ${$res->content_ref} =~ s/\bfoo\b/bar/g;
+
+This example would modify the content buffer in-place.
+
+If an argument is passed it will setup the content to reference some
+external source. The content() and add_content() methods
+will automatically dereference scalar references passed this way. For
+other references content() will return the reference itself and
+add_content() will refuse to do anything.
+
+=item $mess->content_charset
+
+This returns the charset used by the content in the message. The
+charset is either found as the charset attribute of the
+C<Content-Type> header or by guessing.
+
+See L<http://www.w3.org/TR/REC-html40/charset.html#spec-char-encoding>
+for details about how charset is determined.
+
+=item $mess->decoded_content( %options )
+
+Returns the content with any C<Content-Encoding> undone and the raw
+content encoded to perl's Unicode strings. If the C<Content-Encoding>
+or C<charset> of the message is unknown this method will fail by
+returning C<undef>.
+
+The following options can be specified.
+
+=over
+
+=item C<charset>
+
+This override the charset parameter for text content. The value
+C<none> can used to suppress decoding of the charset.
+
+=item C<default_charset>
+
+This override the default charset guessed by content_charset() or
+if that fails "ISO-8859-1".
+
+=item C<alt_charset>
+
+If decoding fails because the charset specified in the Content-Type header
+isn't recognized by Perl's Encode module, then try decoding using this charset
+instead of failing. The C<alt_charset> might be specified as C<none> to simply
+return the string without any decoding of charset as alternative.
+
+=item C<charset_strict>
+
+Abort decoding if malformed characters is found in the content. By
+default you get the substitution character ("\x{FFFD}") in place of
+malformed characters.
+
+=item C<raise_error>
+
+If TRUE then raise an exception if not able to decode content. Reason
+might be that the specified C<Content-Encoding> or C<charset> is not
+supported. If this option is FALSE, then decoded_content() will return
+C<undef> on errors, but will still set $@.
+
+=item C<ref>
+
+If TRUE then a reference to decoded content is returned. This might
+be more efficient in cases where the decoded content is identical to
+the raw content as no data copying is required in this case.
+
+=back
+
+=item $mess->decodable
+
+=item HTTP::Message::decodable()
+
+This returns the encoding identifiers that decoded_content() can
+process. In scalar context returns a comma separated string of
+identifiers.
+
+This value is suitable for initializing the C<Accept-Encoding> request
+header field.
+
+=item $mess->decode
+
+This method tries to replace the content of the message with the
+decoded version and removes the C<Content-Encoding> header. Returns
+TRUE if successful and FALSE if not.
+
+If the message does not have a C<Content-Encoding> header this method
+does nothing and returns TRUE.
+
+Note that the content of the message is still bytes after this method
+has been called and you still need to call decoded_content() if you
+want to process its content as a string.
+
+=item $mess->encode( $encoding, ... )
+
+Apply the given encodings to the content of the message. Returns TRUE
+if successful. The "identity" (non-)encoding is always supported; other
+currently supported encodings, subject to availability of required
+additional modules, are "gzip", "deflate", "x-bzip2" and "base64".
+
+A successful call to this function will set the C<Content-Encoding>
+header.
+
+Note that C<multipart/*> or C<message/*> messages can't be encoded and
+this method will croak if you try.
+
+=item $mess->parts
+
+=item $mess->parts( @parts )
+
+=item $mess->parts( \@parts )
+
+Messages can be composite, i.e. contain other messages. The composite
+messages have a content type of C<multipart/*> or C<message/*>. This
+method give access to the contained messages.
+
+The argumentless form will return a list of C<HTTP::Message> objects.
+If the content type of $msg is not C<multipart/*> or C<message/*> then
+this will return the empty list. In scalar context only the first
+object is returned. The returned message parts should be regarded as
+read-only (future versions of this library might make it possible
+to modify the parent by modifying the parts).
+
+If the content type of $msg is C<message/*> then there will only be
+one part returned.
+
+If the content type is C<message/http>, then the return value will be
+either an C<HTTP::Request> or an C<HTTP::Response> object.
+
+If an @parts argument is given, then the content of the message will be
+modified. The array reference form is provided so that an empty list
+can be provided. The @parts array should contain C<HTTP::Message>
+objects. The @parts objects are owned by $mess after this call and
+should not be modified or made part of other messages.
+
+When updating the message with this method and the old content type of
+$mess is not C<multipart/*> or C<message/*>, then the content type is
+set to C<multipart/mixed> and all other content headers are cleared.
+
+This method will croak if the content type is C<message/*> and more
+than one part is provided.
+
+=item $mess->add_part( $part )
+
+This will add a part to a message. The $part argument should be
+another C<HTTP::Message> object. If the previous content type of
+$mess is not C<multipart/*> then the old content (together with all
+content headers) will be made part #1 and the content type made
+C<multipart/mixed> before the new part is added. The $part object is
+owned by $mess after this call and should not be modified or made part
+of other messages.
+
+There is no return value.
+
+=item $mess->clear
+
+Will clear the headers and set the content to the empty string. There
+is no return value
+
+=item $mess->protocol
+
+=item $mess->protocol( $proto )
+
+Sets the HTTP protocol used for the message. The protocol() is a string
+like C<HTTP/1.0> or C<HTTP/1.1>.
+
+=item $mess->clone
+
+Returns a copy of the message object.
+
+=item $mess->as_string
+
+=item $mess->as_string( $eol )
+
+Returns the message formatted as a single string.
+
+The optional $eol parameter specifies the line ending sequence to use.
+The default is "\n". If no $eol is given then as_string will ensure
+that the returned string is newline terminated (even when the message
+content is not). No extra newline is appended if an explicit $eol is
+passed.
+
+=item $mess->dump( %opt )
+
+Returns the message formatted as a string. In void context print the string.
+
+This differs from C<< $mess->as_string >> in that it escapes the bytes
+of the content so that it's safe to print them and it limits how much
+content to print. The escapes syntax used is the same as for Perl's
+double quoted strings. If there is no content the string "(no
+content)" is shown in its place.
+
+Options to influence the output can be passed as key/value pairs. The
+following options are recognized:
+
+=over
+
+=item maxlength => $num
+
+How much of the content to show. The default is 512. Set this to 0
+for unlimited.
+
+If the content is longer then the string is chopped at the limit and
+the string "...\n(### more bytes not shown)" appended.
+
+=item prefix => $str
+
+A string that will be prefixed to each line of the dump.
+
+=back
+
+=back
+
+All methods unknown to C<HTTP::Message> itself are delegated to the
+C<HTTP::Headers> object that is part of every message. This allows
+convenient access to these methods. Refer to L<HTTP::Headers> for
+details of these methods:
+
+ $mess->header( $field => $val )
+ $mess->push_header( $field => $val )
+ $mess->init_header( $field => $val )

+
+HTTP::Negotiate - choose a variant to serve
+
+=head1 SYNOPSIS
+
+ use HTTP::Negotiate qw(choose);
+
+ # ID QS Content-Type Encoding Char-Set Lang Size
+ $variants =
+ [['var1', 1.000, 'text/html', undef, 'iso-8859-1', 'en', 3000],
+ ['var2', 0.950, 'text/plain', 'gzip', 'us-ascii', 'no', 400],
+ ['var3', 0.3, 'image/gif', undef, undef, undef, 43555],
+ ];
+
+ @preferred = choose($variants, $request_headers);
+ $the_one = choose($variants);
+
+=head1 DESCRIPTION
+
+This module provides a complete implementation of the HTTP content
+negotiation algorithm specified in F<draft-ietf-http-v11-spec-00.ps>
+chapter 12. Content negotiation allows for the selection of a
+preferred content representation based upon attributes of the
+negotiable variants and the value of the various Accept* header fields
+in the request.
+
+The variants are ordered by preference by calling the function
+choose().
+
+The first parameter is reference to an array of the variants to
+choose among.
+Each element in this array is an array with the values [$id, $qs,
+$content_type, $content_encoding, $charset, $content_language,
+$content_length] whose meanings are described
+below. The $content_encoding and $content_language can be either a
+single scalar value or an array reference if there are several values.
+
+The second optional parameter is either a HTTP::Headers or a HTTP::Request
+object which is searched for "Accept*" headers. If this
+parameter is missing, then the accept specification is initialized
+from the CGI environment variables HTTP_ACCEPT, HTTP_ACCEPT_CHARSET,
+HTTP_ACCEPT_ENCODING and HTTP_ACCEPT_LANGUAGE.
+
+In an array context, choose() returns a list of [variant
+identifier, calculated quality, size] tuples. The values are sorted by
+quality, highest quality first. If the calculated quality is the same
+for two variants, then they are sorted by size (smallest first). I<E.g.>:
+
+ (['var1', 1, 2000], ['var2', 0.3, 512], ['var3', 0.3, 1024]);
+
+Note that also zero quality variants are included in the return list
+even if these should never be served to the client.
+
+In a scalar context, it returns the identifier of the variant with the
+highest score or C<undef> if none have non-zero quality.
+
+If the $HTTP::Negotiate::DEBUG variable is set to TRUE, then a lot of
+noise is generated on STDOUT during evaluation of choose().
+
+=head1 VARIANTS
+
+A variant is described by a list of the following values. If the
+attribute does not make sense or is unknown for a variant, then use
+C<undef> instead.
+
+=over 3
+
+=item identifier
+
+This is a string that you use as the name for the variant. This
+identifier for the preferred variants returned by choose().
+
+=item qs
+
+This is a number between 0.000 and 1.000 that describes the "source
+quality". This is what F<draft-ietf-http-v11-spec-00.ps> says about this
+value:
+
+Source quality is measured by the content provider as representing the
+amount of degradation from the original source. For example, a
+picture in JPEG form would have a lower qs when translated to the XBM
+format, and much lower qs when translated to an ASCII-art
+representation. Note, however, that this is a function of the source
+- an original piece of ASCII-art may degrade in quality if it is
+captured in JPEG form. The qs values should be assigned to each
+variant by the content provider; if no qs value has been assigned, the
+default is generally "qs=1".
+
+=item content-type
+
+This is the media type of the variant. The media type does not
+include a charset attribute, but might contain other parameters.
+Examples are:
+
+ text/html
+ text/html;version=2.0
+ text/plain
+ image/gif
+ image/jpg
+
+=item content-encoding
+
+This is one or more content encodings that has been applied to the
+variant. The content encoding is generally used as a modifier to the
+content media type. The most common content encodings are:
+
+ gzip
+ compress
+
+=item content-charset
+
+This is the character set used when the variant contains text.
+The charset value should generally be C<undef> or one of these:
+
+ us-ascii
+ iso-8859-1 ... iso-8859-9
+ iso-2022-jp
+ iso-2022-jp-2
+ iso-2022-kr
+ unicode-1-1
+ unicode-1-1-utf-7
+ unicode-1-1-utf-8
+
+=item content-language
+
+This describes one or more languages that are used in the variant.
+Language is described like this in F<draft-ietf-http-v11-spec-00.ps>: A
+language is in this context a natural language spoken, written, or
+otherwise conveyed by human beings for communication of information to
+other human beings. Computer languages are explicitly excluded.
+
+The language tags are defined by RFC 3066. Examples
+are:
+
+ no Norwegian
+ en International English
+ en-US US English
+ en-cockney
+
+=item content-length
+
+This is the number of bytes used to represent the content.
+
+=back
+
+=head1 ACCEPT HEADERS
+
+The following Accept* headers can be used for describing content
+preferences in a request (This description is an edited extract from
+F<draft-ietf-http-v11-spec-00.ps>):
+
+=over 3
+
+=item Accept
+
+This header can be used to indicate a list of media ranges which are
+acceptable as a response to the request. The "*" character is used to
+group media types into ranges, with "*/*" indicating all media types
+and "type/*" indicating all subtypes of that type.
+
+The parameter q is used to indicate the quality factor, which
+represents the user's preference for that range of media types. The
+parameter mbx gives the maximum acceptable size of the response
+content. The default values are: q=1 and mbx=infinity. If no Accept
+header is present, then the client accepts all media types with q=1.
+
+For example:
+
+ Accept: audio/*;q=0.2;mbx=200000, audio/basic
+
+would mean: "I prefer audio/basic (of any size), but send me any audio
+type if it is the best available after an 80% mark-down in quality and
+its size is less than 200000 bytes"
+
+
+=item Accept-Charset
+
+Used to indicate what character sets are acceptable for the response.
+The "us-ascii" character set is assumed to be acceptable for all user
+agents. If no Accept-Charset field is given, the default is that any
+charset is acceptable. Example:
+
+ Accept-Charset: iso-8859-1, unicode-1-1
+
+
+=item Accept-Encoding
+
+Restricts the Content-Encoding values which are acceptable in the
+response. If no Accept-Encoding field is present, the server may
+assume that the client will accept any content encoding. An empty
+Accept-Encoding means that no content encoding is acceptable. Example:
+
+ Accept-Encoding: compress, gzip
+
+
+=item Accept-Language
+
+This field is similar to Accept, but restricts the set of natural
+languages that are preferred in a response. Each language may be
+given an associated quality value which represents an estimate of the
+user's comprehension of that language. For example:
+
+ Accept-Language: no, en-gb;q=0.8, de;q=0.55
+
+would mean: "I prefer Norwegian, but will accept British English (with
+80% comprehension) or German (with 55% comprehension).

+=head1 NAME
+
+HTTP::Request - HTTP style request message
+
+=head1 SYNOPSIS
+
+ require HTTP::Request;
+ $request = HTTP::Request->new(GET => 'http://www.example.com/');
+
+and usually used like this:
+
+ $ua = LWP::UserAgent->new;
+ $response = $ua->request($request);
+
+=head1 DESCRIPTION
+
+C<HTTP::Request> is a class encapsulating HTTP style requests,
+consisting of a request line, some headers, and a content body. Note
+that the LWP library uses HTTP style requests even for non-HTTP
+protocols. Instances of this class are usually passed to the
+request() method of an C<LWP::UserAgent> object.
+
+C<HTTP::Request> is a subclass of C<HTTP::Message> and therefore
+inherits its methods. The following additional methods are available:
+
+=over 4
+
+=item $r = HTTP::Request->new( $method, $uri )
+
+=item $r = HTTP::Request->new( $method, $uri, $header )
+
+=item $r = HTTP::Request->new( $method, $uri, $header, $content )
+
+Constructs a new C<HTTP::Request> object describing a request on the
+object $uri using method $method. The $method argument must be a
+string. The $uri argument can be either a string, or a reference to a
+C<URI> object. The optional $header argument should be a reference to
+an C<HTTP::Headers> object or a plain array reference of key/value
+pairs. The optional $content argument should be a string of bytes.
+
+=item $r = HTTP::Request->parse( $str )
+
+This constructs a new request object by parsing the given string.
+
+=item $r->method
+
+=item $r->method( $val )
+
+This is used to get/set the method attribute. The method should be a
+short string like "GET", "HEAD", "PUT" or "POST".
+
+=item $r->uri
+
+=item $r->uri( $val )
+
+This is used to get/set the uri attribute. The $val can be a
+reference to a URI object or a plain string. If a string is given,
+then it should be parseable as an absolute URI.
+
+=item $r->header( $field )
+
+=item $r->header( $field => $value )
+
+This is used to get/set header values and it is inherited from
+C<HTTP::Headers> via C<HTTP::Message>. See L<HTTP::Headers> for
+details and other similar methods that can be used to access the
+headers.
+
+=item $r->accept_decodable
+
+This will set the C<Accept-Encoding> header to the list of encodings
+that decoded_content() can decode.
+
+=item $r->content
+
+=item $r->content( $bytes )
+
+This is used to get/set the content and it is inherited from the
+C<HTTP::Message> base class. See L<HTTP::Message> for details and
+other methods that can be used to access the content.
+
+Note that the content should be a string of bytes. Strings in perl
+can contain characters outside the range of a byte. The C<Encode>
+module can be used to turn such strings into a string of bytes.
+
+=item $r->as_string
+
+=item $r->as_string( $eol )
+
+Method returning a textual representation of the request.

+
+HTTP::Request::Common - Construct common HTTP::Request objects
+
+=head1 SYNOPSIS
+
+ use HTTP::Request::Common;
+ $ua = LWP::UserAgent->new;
+ $ua->request(GET 'http://www.sn.no/');
+ $ua->request(POST 'http://somewhere/foo', [foo => bar, bar => foo]);
+
+=head1 DESCRIPTION
+
+This module provide functions that return newly created C<HTTP::Request>
+objects. These functions are usually more convenient to use than the
+standard C<HTTP::Request> constructor for the most common requests. The
+following functions are provided:
+
+=over 4
+
+=item GET $url
+
+=item GET $url, Header => Value,...
+
+The GET() function returns an C<HTTP::Request> object initialized with
+the "GET" method and the specified URL. It is roughly equivalent to the
+following call
+
+ HTTP::Request->new(
+ GET => $url,
+ HTTP::Headers->new(Header => Value,...),
+ )
+
+but is less cluttered. What is different is that a header named
+C<Content> will initialize the content part of the request instead of
+setting a header field. Note that GET requests should normally not
+have a content, so this hack makes more sense for the PUT() and POST()
+functions described below.
+
+The get(...) method of C<LWP::UserAgent> exists as a shortcut for
+$ua->request(GET ...).
+
+=item HEAD $url
+
+=item HEAD $url, Header => Value,...
+
+Like GET() but the method in the request is "HEAD".
+
+The head(...) method of "LWP::UserAgent" exists as a shortcut for
+$ua->request(HEAD ...).
+
+=item PUT $url
+
+=item PUT $url, Header => Value,...
+
+=item PUT $url, Header => Value,..., Content => $content
+
+Like GET() but the method in the request is "PUT".
+
+The content of the request can be specified using the "Content"
+pseudo-header. This steals a bit of the header field namespace as
+there is no way to directly specify a header that is actually called
+"Content". If you really need this you must update the request
+returned in a separate statement.
+
+=item DELETE $url
+
+=item DELETE $url, Header => Value,...
+
+Like GET() but the method in the request is "DELETE". This function
+is not exported by default.
+
+=item POST $url
+
+=item POST $url, Header => Value,...
+
+=item POST $url, $form_ref, Header => Value,...
+
+=item POST $url, Header => Value,..., Content => $form_ref
+
+=item POST $url, Header => Value,..., Content => $content
+
+This works mostly like PUT() with "POST" as the method, but this
+function also takes a second optional array or hash reference
+parameter $form_ref. As for PUT() the content can also be specified
+directly using the "Content" pseudo-header, and you may also provide
+the $form_ref this way.
+
+The $form_ref argument can be used to pass key/value pairs for the
+form content. By default we will initialize a request using the
+C<application/x-www-form-urlencoded> content type. This means that
+you can emulate a HTML E<lt>form> POSTing like this:
+
+ POST 'http://www.perl.org/survey.cgi',
+ [ name => 'Gisle Aas',
+ email => 'gisle@aas.no',
+ gender => 'M',
+ born => '1964',
+ perc => '3%',
+ ];
+
+This will create a HTTP::Request object that looks like this:
+
+ POST http://www.perl.org/survey.cgi
+ Content-Length: 66
+ Content-Type: application/x-www-form-urlencoded
+
+ name=Gisle%20Aas&email=gisle%40aas.no&gender=M&born=1964&perc=3%25
+
+Multivalued form fields can be specified by either repeating the field
+name or by passing the value as an array reference.
+
+The POST method also supports the C<multipart/form-data> content used
+for I<Form-based File Upload> as specified in RFC 1867. You trigger
+this content format by specifying a content type of C<'form-data'> as
+one of the request headers. If one of the values in the $form_ref is
+an array reference, then it is treated as a file part specification
+with the following interpretation:
+
+ [ $file, $filename, Header => Value... ]
+ [ undef, $filename, Header => Value,..., Content => $content ]
+
+The first value in the array ($file) is the name of a file to open.
+This file will be read and its content placed in the request. The
+routine will croak if the file can't be opened. Use an C<undef> as
+$file value if you want to specify the content directly with a
+C<Content> header. The $filename is the filename to report in the
+request. If this value is undefined, then the basename of the $file
+will be used. You can specify an empty string as $filename if you
+want to suppress sending the filename when you provide a $file value.
+
+If a $file is provided by no C<Content-Type> header, then C<Content-Type>
+and C<Content-Encoding> will be filled in automatically with the values
+returned by LWP::MediaTypes::guess_media_type()
+
+Sending my F<~/.profile> to the survey used as example above can be
+achieved by this:
+
+ POST 'http://www.perl.org/survey.cgi',
+ Content_Type => 'form-data',
+ Content => [ name => 'Gisle Aas',
+ email => 'gisle@aas.no',
+ gender => 'M',
+ born => '1964',
+ init => ["$ENV{HOME}/.profile"],
+ ]
+
+This will create a HTTP::Request object that almost looks this (the
+boundary and the content of your F<~/.profile> is likely to be
+different):
+
+ POST http://www.perl.org/survey.cgi
+ Content-Length: 388
+ Content-Type: multipart/form-data; boundary="6G+f"
+
+ --6G+f
+ Content-Disposition: form-data; name="name"
+
+ Gisle Aas
+ --6G+f

+If you set the $DYNAMIC_FILE_UPLOAD variable (exportable) to some TRUE
+value, then you get back a request object with a subroutine closure as
+the content attribute. This subroutine will read the content of any
+files on demand and return it in suitable chunks. This allow you to
+upload arbitrary big files without using lots of memory. You can even
+upload infinite files like F</dev/audio> if you wish; however, if
+the file is not a plain file, there will be no Content-Length header
+defined for the request. Not all servers (or server
+applications) like this. Also, if the file(s) change in size between
+the time the Content-Length is calculated and the time that the last
+chunk is delivered, the subroutine will C<Croak>.

+The post(...) method of "LWP::UserAgent" exists as a shortcut for
+$ua->request(POST ...).

+=head1 NAME
+
+HTTP::Response - HTTP style response message
+
+=head1 SYNOPSIS
+
+Response objects are returned by the request() method of the C<LWP::UserAgent>:
+
+ # ...
+ $response = $ua->request($request)
+ if ($response->is_success) {
+ print $response->decoded_content;
+ }
+ else {
+ print STDERR $response->status_line, "\n";
+ }
+
+=head1 DESCRIPTION
+
+The C<HTTP::Response> class encapsulates HTTP style responses. A
+response consists of a response line, some headers, and a content
+body. Note that the LWP library uses HTTP style responses even for
+non-HTTP protocol schemes. Instances of this class are usually
+created and returned by the request() method of an C<LWP::UserAgent>
+object.
+
+C<HTTP::Response> is a subclass of C<HTTP::Message> and therefore
+inherits its methods. The following additional methods are available:
+
+=over 4
+
+=item $r = HTTP::Response->new( $code )
+
+=item $r = HTTP::Response->new( $code, $msg )
+
+=item $r = HTTP::Response->new( $code, $msg, $header )
+
+=item $r = HTTP::Response->new( $code, $msg, $header, $content )
+
+Constructs a new C<HTTP::Response> object describing a response with
+response code $code and optional message $msg. The optional $header
+argument should be a reference to an C<HTTP::Headers> object or a
+plain array reference of key/value pairs. The optional $content
+argument should be a string of bytes. The meaning these arguments are
+described below.
+
+=item $r = HTTP::Response->parse( $str )
+
+This constructs a new response object by parsing the given string.
+
+=item $r->code
+
+=item $r->code( $code )
+
+This is used to get/set the code attribute. The code is a 3 digit
+number that encode the overall outcome of a HTTP response. The
+C<HTTP::Status> module provide constants that provide mnemonic names
+for the code attribute.
+
+=item $r->message
+
+=item $r->message( $message )
+
+This is used to get/set the message attribute. The message is a short
+human readable single line string that explains the response code.
+
+=item $r->header( $field )
+
+=item $r->header( $field => $value )
+
+This is used to get/set header values and it is inherited from
+C<HTTP::Headers> via C<HTTP::Message>. See L<HTTP::Headers> for
+details and other similar methods that can be used to access the
+headers.
+
+=item $r->content
+
+=item $r->content( $bytes )
+
+This is used to get/set the raw content and it is inherited from the
+C<HTTP::Message> base class. See L<HTTP::Message> for details and
+other methods that can be used to access the content.
+
+=item $r->decoded_content( %options )
+
+This will return the content after any C<Content-Encoding> and
+charsets have been decoded. See L<HTTP::Message> for details.
+
+=item $r->request
+
+=item $r->request( $request )
+
+This is used to get/set the request attribute. The request attribute
+is a reference to the the request that caused this response. It does
+not have to be the same request passed to the $ua->request() method,
+because there might have been redirects and authorization retries in
+between.
+
+=item $r->previous
+
+=item $r->previous( $response )
+
+This is used to get/set the previous attribute. The previous
+attribute is used to link together chains of responses. You get
+chains of responses if the first response is redirect or unauthorized.
+The value is C<undef> if this is the first response in a chain.
+
+Note that the method $r->redirects is provided as a more convenient
+way to access the response chain.
+
+=item $r->status_line
+
+Returns the string "E<lt>code> E<lt>message>". If the message attribute
+is not set then the official name of E<lt>code> (see L<HTTP::Status>)
+is substituted.
+
+=item $r->base
+
+Returns the base URI for this response. The return value will be a
+reference to a URI object.
+
+The base URI is obtained from one the following sources (in priority
+order):
+
+=over 4
+
+=item 1.
+
+Embedded in the document content, for instance <BASE HREF="...">
+in HTML documents.
+
+=item 2.
+
+A "Content-Base:" or a "Content-Location:" header in the response.
+
+For backwards compatibility with older HTTP implementations we will
+also look for the "Base:" header.
+
+=item 3.
+
+The URI used to request this response. This might not be the original
+URI that was passed to $ua->request() method, because we might have
+received some redirect responses first.
+
+=back
+
+If none of these sources provide an absolute URI, undef is returned.
+
+When the LWP protocol modules produce the HTTP::Response object, then
+any base URI embedded in the document (step 1) will already have
+initialized the "Content-Base:" header. This means that this method
+only performs the last 2 steps (the content is not always available
+either).
+
+=item $r->filename
+
+Returns a filename for this response. Note that doing sanity checks
+on the returned filename (eg. removing characters that cannot be used
+on the target filesystem where the filename would be used, and
+laundering it for security purposes) are the caller's responsibility;
+the only related thing done by this method is that it makes a simple
+attempt to return a plain filename with no preceding path segments.
+
+The filename is obtained from one the following sources (in priority
+order):
+
+=over 4
+
+=item 1.
+
+A "Content-Disposition:" header in the response. Proper decoding of
+RFC 2047 encoded filenames requires the C<MIME::QuotedPrint> (for "Q"
+encoding), C<MIME::Base64> (for "B" encoding), and C<Encode> modules.
+
+=item 2.
+
+A "Content-Location:" header in the response.
+
+=item 3.
+
+The URI used to request this response. This might not be the original
+URI that was passed to $ua->request() method, because we might have
+received some redirect responses first.
+
+=back
+
+If a filename cannot be derived from any of these sources, undef is
+returned.
+
+=item $r->as_string
+
+=item $r->as_string( $eol )
+
+Returns a textual representation of the response.
+
+=item $r->is_info
+
+=item $r->is_success
+
+=item $r->is_redirect
+
+=item $r->is_error
+
+These methods indicate if the response was informational, successful, a
+redirection, or an error. See L<HTTP::Status> for the meaning of these.
+
+=item $r->error_as_HTML
+
+Returns a string containing a complete HTML document indicating what
+error occurred. This method should only be called when $r->is_error
+is TRUE.
+
+=item $r->redirects
+
+Returns the list of redirect responses that lead up to this response
+by following the $r->previous chain. The list order is oldest first.
+
+In scalar context return the number of redirect responses leading up
+to this one.
+
+=item $r->current_age
+
+Calculates the "current age" of the response as specified by RFC 2616
+section 13.2.3. The age of a response is the time since it was sent
+by the origin server. The returned value is a number representing the
+age in seconds.
+
+=item $r->freshness_lifetime( %opt )
+
+Calculates the "freshness lifetime" of the response as specified by
+RFC 2616 section 13.2.4. The "freshness lifetime" is the length of
+time between the generation of a response and its expiration time.
+The returned value is the number of seconds until expiry.
+
+If the response does not contain an "Expires" or a "Cache-Control"
+header, then this function will apply some simple heuristic based on
+the "Last-Modified" header to determine a suitable lifetime. The
+following options might be passed to control the heuristics:
+
+=over
+
+=item heuristic_expiry => $bool
+
+If passed as a FALSE value, don't apply heuristics and just return
+C<undef> when "Expires" or "Cache-Control" is lacking.
+
+=item h_lastmod_fraction => $num
+
+This number represent the fraction of the difference since the
+"Last-Modified" timestamp to make the expiry time. The default is
+C<0.10>, the suggested typical setting of 10% in RFC 2616.
+
+=item h_min => $sec
+
+This is the lower limit of the heuristic expiry age to use. The
+default is C<60> (1 minute).
+
+=item h_max => $sec
+
+This is the upper limit of the heuristic expiry age to use. The
+default is C<86400> (24 hours).
+
+=item h_default => $sec
+
+This is the expiry age to use when nothing else applies. The default
+is C<3600> (1 hour) or "h_min" if greater.
+
+=back
+
+=item $r->is_fresh( %opt )
+
+Returns TRUE if the response is fresh, based on the values of
+freshness_lifetime() and current_age(). If the response is no longer
+fresh, then it has to be re-fetched or re-validated by the origin
+server.
+
+Options might be passed to control expiry heuristics, see the
+description of freshness_lifetime().
+
+=item $r->fresh_until( %opt )
+
+Returns the time (seconds since epoch) when this entity is no longer fresh.
+
+Options might be passed to control expiry heuristics, see the
+description of freshness_lifetime().

+=head1 FUNCTIONS
+
+The following additional functions are provided. Most of them are
+exported by default. The C<:is> import tag can be used to import all
+the classification functions.
+
+=over 4
+
+=item status_message( $code )
+
+The status_message() function will translate status codes to human
+readable strings. The string is the same as found in the constant
+names above. If the $code is unknown, then C<undef> is returned.
+
+=item is_info( $code )
+
+Return TRUE if C<$code> is an I<Informational> status code (1xx). This
+class of status code indicates a provisional response which can't have
+any content.
+
+=item is_success( $code )
+
+Return TRUE if C<$code> is a I<Successful> status code (2xx).
+
+=item is_redirect( $code )
+
+Return TRUE if C<$code> is a I<Redirection> status code (3xx). This class of
+status code indicates that further action needs to be taken by the
+user agent in order to fulfill the request.
+
+=item is_error( $code )
+
+Return TRUE if C<$code> is an I<Error> status code (4xx or 5xx). The function
+return TRUE for both client error or a server error status codes.
+
+=item is_client_error( $code )
+
+Return TRUE if C<$code> is an I<Client Error> status code (4xx). This class
+of status code is intended for cases in which the client seems to have
+erred.
+
+This function is B<not> exported by default.
+
+=item is_server_error( $code )
+
+Return TRUE if C<$code> is an I<Server Error> status code (5xx). This class
+of status codes is intended for cases in which the server is aware
+that it has erred or is incapable of performing the request.
+
+This function is B<not> exported by default.
+
+=back
+
+=head1 BUGS
+
+For legacy reasons all the C<HTTP_> constants are exported by default
+with the prefix C<RC_>. It's recommended to use explict imports and
+the C<:constants> tag instead of relying on this.

+LWP - The World-Wide Web library for Perl
+
+=head1 SYNOPSIS
+
+ use LWP;
+ print "This is libwww-perl-$LWP::VERSION\n";
+
+
+=head1 DESCRIPTION
+
+The libwww-perl collection is a set of Perl modules which provides a
+simple and consistent application programming interface (API) to the
+World-Wide Web. The main focus of the library is to provide classes
+and functions that allow you to write WWW clients. The library also
+contain modules that are of more general use and even classes that
+help you implement simple HTTP servers.
+
+Most modules in this library provide an object oriented API. The user
+agent, requests sent and responses received from the WWW server are
+all represented by objects. This makes a simple and powerful
+interface to these services. The interface is easy to extend
+and customize for your own needs.
+
+The main features of the library are:
+
+=over 3
+
+=item *
+
+Contains various reusable components (modules) that can be
+used separately or together.
+
+=item *

+this framework we currently support access to http, https, gopher, ftp, news,
+file, and mailto resources.
+

+
+=item *
+
+Supports parsing of HTML forms.
+

+
+
+=head1 HTTP STYLE COMMUNICATION
+
+
+The libwww-perl library is based on HTTP style communication. This
+section tries to describe what that means.
+
+Let us start with this quote from the HTTP specification document
+<URL:http://www.w3.org/pub/WWW/Protocols/>:
+
+=over 3
+
+=item
+
+The HTTP protocol is based on a request/response paradigm. A client
+establishes a connection with a server and sends a request to the
+server in the form of a request method, URI, and protocol version,
+followed by a MIME-like message containing request modifiers, client
+information, and possible body content. The server responds with a
+status line, including the message's protocol version and a success or
+error code, followed by a MIME-like message containing server
+information, entity meta-information, and possible body content.
+
+=back
+
+What this means to libwww-perl is that communication always take place
+through these steps: First a I<request> object is created and
+configured. This object is then passed to a server and we get a
+I<response> object in return that we can examine. A request is always
+independent of any previous requests, i.e. the service is stateless.
+The same simple model is used for any kind of service we want to
+access.
+
+For example, if we want to fetch a document from a remote file server,
+then we send it a request that contains a name for that document and
+the response will contain the document itself. If we access a search
+engine, then the content of the request will contain the query
+parameters and the response will contain the query result. If we want
+to send a mail message to somebody then we send a request object which
+contains our message to the mail server and the response object will
+contain an acknowledgment that tells us that the message has been
+accepted and will be forwarded to the recipient(s).
+
+It is as simple as that!
+
+
+=head2 The Request Object
+
+The libwww-perl request object has the class name C<HTTP::Request>.
+The fact that the class name uses C<HTTP::> as a
+prefix only implies that we use the HTTP model of communication. It
+does not limit the kind of services we can try to pass this I<request>
+to. For instance, we will send C<HTTP::Request>s both to ftp and
+gopher servers, as well as to the local file system.
+
+The main attributes of the request objects are:
+
+=over 3
+
+=item *
+
+The B<method> is a short string that tells what kind of
+request this is. The most common methods are B<GET>, B<PUT>,
+B<POST> and B<HEAD>.
+
+=item *
+
+The B<uri> is a string denoting the protocol, server and
+the name of the "document" we want to access. The B<uri> might
+also encode various other parameters.
+
+=item *
+
+The B<headers> contain additional information about the
+request and can also used to describe the content. The headers
+are a set of keyword/value pairs.
+
+=item *
+
+The B<content> is an arbitrary amount of data.
+
+=back
+
+=head2 The Response Object
+
+The libwww-perl response object has the class name C<HTTP::Response>.
+The main attributes of objects of this class are:
+
+=over 3
+
+=item *
+
+The B<code> is a numerical value that indicates the overall
+outcome of the request.
+
+=item *
+
+The B<message> is a short, human readable string that
+corresponds to the I<code>.
+
+=item *
+
+The B<headers> contain additional information about the
+response and describe the content.
+
+=item *
+
+The B<content> is an arbitrary amount of data.
+
+=back
+
+Since we don't want to handle all possible I<code> values directly in
+our programs, a libwww-perl response object has methods that can be
+used to query what kind of response this is. The most commonly used
+response classification methods are:
+
+=over 3
+
+=item is_success()
+
+The request was was successfully received, understood or accepted.
+
+=item is_error()
+
+The request failed. The server or the resource might not be
+available, access to the resource might be denied or other things might
+have failed for some reason.
+
+=back
+
+=head2 The User Agent
+
+Let us assume that we have created a I<request> object. What do we
+actually do with it in order to receive a I<response>?
+
+The answer is that you pass it to a I<user agent> object and this
+object takes care of all the things that need to be done
+(like low-level communication and error handling) and returns
+a I<response> object. The user agent represents your
+application on the network and provides you with an interface that
+can accept I<requests> and return I<responses>.
+
+The user agent is an interface layer between
+your application code and the network. Through this interface you are
+able to access the various servers on the network.
+
+The class name for the user agent is C<LWP::UserAgent>. Every
+libwww-perl application that wants to communicate should create at
+least one object of this class. The main method provided by this
+object is request(). This method takes an C<HTTP::Request> object as
+argument and (eventually) returns a C<HTTP::Response> object.
+
+The user agent has many other attributes that let you
+configure how it will interact with the network and with your
+application.
+
+=over 3
+
+=item *
+
+The B<timeout> specifies how much time we give remote servers to
+respond before the library disconnects and creates an
+internal I<timeout> response.
+
+=item *
+
+The B<agent> specifies the name that your application should use when it
+presents itself on the network.
+
+=item *
+
+The B<from> attribute can be set to the e-mail address of the person
+responsible for running the application. If this is set, then the
+address will be sent to the servers with every request.
+
+=item *
+
+The B<parse_head> specifies whether we should initialize response
+headers from the E<lt>head> section of HTML documents.
+
+=item *
+
+The B<proxy> and B<no_proxy> attributes specify if and when to go through
+a proxy server. <URL:http://www.w3.org/pub/WWW/Proxies/>
+
+=item *
+
+The B<credentials> provide a way to set up user names and
+passwords needed to access certain services.
+
+=back
+
+Many applications want even more control over how they interact
+with the network and they get this by sub-classing
+C<LWP::UserAgent>. The library includes a
+sub-class, C<LWP::RobotUA>, for robot applications.
+
+=head2 An Example
+
+This example shows how the user agent, a request and a response are
+represented in actual perl code:
+
+ # Create a user agent object
+ use LWP::UserAgent;
+ my $ua = LWP::UserAgent->new;
+ $ua->agent("MyApp/0.1 ");
+
+ # Create a request
+ my $req = HTTP::Request->new(POST => 'http://search.cpan.org/search');
+ $req->content_type('application/x-www-form-urlencoded');
+ $req->content('query=libwww-perl&mode=dist');
+
+ # Pass request to the user agent and get a response back
+ my $res = $ua->request($req);
+
+ # Check the outcome of the response
+ if ($res->is_success) {
+ print $res->content;
+ }
+ else {
+ print $res->status_line, "\n";
+ }
+
+The $ua is created once when the application starts up. New request
+objects should normally created for each request sent.
+
+
+=head1 NETWORK SUPPORT
+
+This section discusses the various protocol schemes and
+the HTTP style methods that headers may be used for each.
+
+For all requests, a "User-Agent" header is added and initialized from
+the $ua->agent attribute before the request is handed to the network
+layer. In the same way, a "From" header is initialized from the
+$ua->from attribute.
+
+For all responses, the library adds a header called "Client-Date".
+This header holds the time when the response was received by
+your application. The format and semantics of the header are the
+same as the server created "Date" header. You may also encounter other
+"Client-XXX" headers. They are all generated by the library
+internally and are not received from the servers.
+
+=head2 HTTP Requests
+
+HTTP requests are just handed off to an HTTP server and it
+decides what happens. Few servers implement methods beside the usual
+"GET", "HEAD", "POST" and "PUT", but CGI-scripts may implement
+any method they like.
+
+If the server is not available then the library will generate an
+internal error response.
+
+The library automatically adds a "Host" and a "Content-Length" header
+to the HTTP request before it is sent over the network.
+
+For a GET request you might want to add a "If-Modified-Since" or
+"If-None-Match" header to make the request conditional.
+
+For a POST request you should add the "Content-Type" header. When you
+try to emulate HTML E<lt>FORM> handling you should usually let the value
+of the "Content-Type" header be "application/x-www-form-urlencoded".
+See L<lwpcook> for examples of this.
+
+The libwww-perl HTTP implementation currently support the HTTP/1.1
+and HTTP/1.0 protocol.
+
+The library allows you to access proxy server through HTTP. This
+means that you can set up the library to forward all types of request
+through the HTTP protocol module. See L<LWP::UserAgent> for
+documentation of this.
+
+
+=head2 HTTPS Requests
+
+HTTPS requests are HTTP requests over an encrypted network connection
+using the SSL protocol developed by Netscape. Everything about HTTP
+requests above also apply to HTTPS requests. In addition the library
+will add the headers "Client-SSL-Cipher", "Client-SSL-Cert-Subject" and
+"Client-SSL-Cert-Issuer" to the response. These headers denote the
+encryption method used and the name of the server owner.
+
+The request can contain the header "If-SSL-Cert-Subject" in order to
+make the request conditional on the content of the server certificate.
+If the certificate subject does not match, no request is sent to the
+server and an internally generated error response is returned. The
+value of the "If-SSL-Cert-Subject" header is interpreted as a Perl
+regular expression.
+
+
+=head2 FTP Requests
+
+The library currently supports GET, HEAD and PUT requests. GET
+retrieves a file or a directory listing from an FTP server. PUT
+stores a file on a ftp server.
+
+You can specify a ftp account for servers that want this in addition
+to user name and password. This is specified by including an "Account"
+header in the request.
+
+User name/password can be specified using basic authorization or be
+encoded in the URL. Failed logins return an UNAUTHORIZED response with
+"WWW-Authenticate: Basic" and can be treated like basic authorization
+for HTTP.
+
+The library supports ftp ASCII transfer mode by specifying the "type=a"
+parameter in the URL. It also supports transfer of ranges for FTP transfers
+using the "Range" header.
+
+Directory listings are by default returned unprocessed (as returned
+from the ftp server) with the content media type reported to be
+"text/ftp-dir-listing". The C<File::Listing> module provides methods
+for parsing of these directory listing.
+
+The ftp module is also able to convert directory listings to HTML and
+this can be requested via the standard HTTP content negotiation
+mechanisms (add an "Accept: text/html" header in the request if you
+want this).
+
+For normal file retrievals, the "Content-Type" is guessed based on the
+file name suffix. See L<LWP::MediaTypes>.
+
+The "If-Modified-Since" request header works for servers that implement
+the MDTM command. It will probably not work for directory listings though.
+
+Example:
+
+ $req = HTTP::Request->new(GET => 'ftp://me:passwd@ftp.some.where.com/');
+ $req->header(Accept => "text/html, */*;q=0.1");
+
+=head2 News Requests
+
+Access to the USENET News system is implemented through the NNTP
+protocol. The name of the news server is obtained from the
+NNTP_SERVER environment variable and defaults to "news". It is not
+possible to specify the hostname of the NNTP server in news: URLs.
+
+The library supports GET and HEAD to retrieve news articles through the
+NNTP protocol. You can also post articles to newsgroups by using
+(surprise!) the POST method.
+
+GET on newsgroups is not implemented yet.
+
+Examples:
+
+ $req = HTTP::Request->new(GET => 'news:abc1234@a.sn.no');
+
+ $req = HTTP::Request->new(POST => 'news:comp.lang.perl.test');
+ $req->header(Subject => 'This is a test',
+ From => 'me@some.where.org');
+ $req->content(<<EOT);
+ This is the content of the message that we are sending to
+ the world.
+ EOT
+
+
+=head2 Gopher Request
+
+The library supports the GET and HEAD methods for gopher requests. All
+request header values are ignored. HEAD cheats and returns a
+response without even talking to server.
+
+Gopher menus are always converted to HTML.
+
+The response "Content-Type" is generated from the document type
+encoded (as the first letter) in the request URL path itself.
+
+Example:
+
+ $req = HTTP::Request->new(GET => 'gopher://gopher.sn.no/');
+
+
+
+=head2 File Request
+
+The library supports GET and HEAD methods for file requests. The
+"If-Modified-Since" header is supported. All other headers are
+ignored. The I<host> component of the file URL must be empty or set
+to "localhost". Any other I<host> value will be treated as an error.
+
+Directories are always converted to an HTML document. For normal
+files, the "Content-Type" and "Content-Encoding" in the response are
+guessed based on the file suffix.
+
+Example:
+
+ $req = HTTP::Request->new(GET => 'file:/etc/passwd');
+
+
+=head2 Mailto Request
+
+You can send (aka "POST") mail messages using the library. All
+headers specified for the request are passed on to the mail system.
+The "To" header is initialized from the mail address in the URL.
+
+Example:
+
+ $req = HTTP::Request->new(POST => 'mailto:libwww@perl.org');
+ $req->header(Subject => "subscribe");
+ $req->content("Please subscribe me to the libwww-perl mailing list!\n");
+
+=head2 CPAN Requests
+
+URLs with scheme C<cpan:> are redirected to the a suitable CPAN
+mirror. If you have your own local mirror of CPAN you might tell LWP
+to use it for C<cpan:> URLs by an assignment like this:
+
+ $LWP::Protocol::cpan::CPAN = "file:/local/CPAN/";
+
+Suitable CPAN mirrors are also picked up from the configuration for
+the CPAN.pm, so if you have used that module a suitable mirror should
+be picked automatically. If neither of these apply, then a redirect
+to the generic CPAN http location is issued.
+
+Example request to download the newest perl:
+
+ $req = HTTP::Request->new(GET => "cpan:src/latest.tar.gz");
+

+=head1 NAME
+
+LWP::Authen::Ntlm - Library for enabling NTLM authentication (Microsoft) in LWP
+
+=head1 SYNOPSIS
+
+ use LWP::UserAgent;
+ use HTTP::Request::Common;
+ my $url = 'http://www.company.com/protected_page.html';
+
+ # Set up the ntlm client and then the base64 encoded ntlm handshake message
+ my $ua = LWP::UserAgent->new(keep_alive=>1);
+ $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');
+
+ $request = GET $url;
+ print "--Performing request now...-----------\n";
+ $response = $ua->request($request);
+ print "--Done with request-------------------\n";
+
+ if ($response->is_success) {print "It worked!->" . $response->code . "\n"}
+ else {print "It didn't work!->" . $response->code . "\n"}
+
+=head1 DESCRIPTION
+
+C<LWP::Authen::Ntlm> allows LWP to authenticate against servers that are using the
+NTLM authentication scheme popularized by Microsoft. This type of authentication is
+common on intranets of Microsoft-centric organizations.
+
+The module takes advantage of the Authen::NTLM module by Mark Bush. Since there
+is also another Authen::NTLM module available from CPAN by Yee Man Chan with an
+entirely different interface, it is necessary to ensure that you have the correct
+NTLM module.
+
+In addition, there have been problems with incompatibilities between different
+versions of Mime::Base64, which Bush's Authen::NTLM makes use of. Therefore, it is
+necessary to ensure that your Mime::Base64 module supports exporting of the
+encode_base64 and decode_base64 functions.
+
+=head1 USAGE
+
+The module is used indirectly through LWP, rather than including it directly in your
+code. The LWP system will invoke the NTLM authentication when it encounters the
+authentication scheme while attempting to retrieve a URL from a server. In order
+for the NTLM authentication to work, you must have a few things set up in your
+code prior to attempting to retrieve the URL:
+
+=over 4
+
+=item *
+
+Enable persistent HTTP connections
+
+To do this, pass the "keep_alive=>1" option to the LWP::UserAgent when creating it, like this:
+
+ my $ua = LWP::UserAgent->new(keep_alive=>1);
+
+=item *
+
+Set the credentials on the UserAgent object
+
+The credentials must be set like this:
+
+ $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');
+
+Note that you cannot use the HTTP::Request object's authorization_basic() method to set
+the credentials. Note, too, that the 'www.company.com:80' portion only sets credentials
+on the specified port AND it is case-sensitive (this is due to the way LWP is coded, and
+has nothing to do with LWP::Authen::Ntlm)
+
+=back
+

+
+General queries regarding LWP should be made to the LWP Mailing List.

+=head1 NAME
+
+LWP::ConnCache - Connection cache manager
+
+=head1 NOTE
+
+This module is experimental. Details of its interface is likely to
+change in the future.
+
+=head1 SYNOPSIS
+
+ use LWP::ConnCache;
+ my $cache = LWP::ConnCache->new;
+ $cache->deposit($type, $key, $sock);
+ $sock = $cache->withdraw($type, $key);
+
+=head1 DESCRIPTION
+
+The C<LWP::ConnCache> class is the standard connection cache manager
+for LWP::UserAgent.
+
+The following basic methods are provided:
+
+=over
+
+=item $cache = LWP::ConnCache->new( %options )
+
+This method constructs a new C<LWP::ConnCache> object. The only
+option currently accepted is 'total_capacity'. If specified it
+initialize the total_capacity option. It defaults to the value 1.
+
+=item $cache->total_capacity( [$num_connections] )
+
+Get/sets the number of connection that will be cached. Connections
+will start to be dropped when this limit is reached. If set to C<0>,
+then all connections are immediately dropped. If set to C<undef>,
+then there is no limit.
+
+=item $cache->capacity($type, [$num_connections] )
+
+Get/set a limit for the number of connections of the specified type
+that can be cached. The $type will typically be a short string like
+"http" or "ftp".
+
+=item $cache->drop( [$checker, [$reason]] )
+
+Drop connections by some criteria. The $checker argument is a
+subroutine that is called for each connection. If the routine returns
+a TRUE value then the connection is dropped. The routine is called
+with ($conn, $type, $key, $deposit_time) as arguments.
+
+Shortcuts: If the $checker argument is absent (or C<undef>) all cached
+connections are dropped. If the $checker is a number then all
+connections untouched that the given number of seconds or more are
+dropped. If $checker is a string then all connections of the given
+type are dropped.
+
+The $reason argument is passed on to the dropped() method.
+
+=item $cache->prune
+
+Calling this method will drop all connections that are dead. This is
+tested by calling the ping() method on the connections. If the ping()
+method exists and returns a FALSE value, then the connection is
+dropped.
+
+=item $cache->get_types
+
+This returns all the 'type' fields used for the currently cached
+connections.
+
+=item $cache->get_connections( [$type] )
+
+This returns all connection objects of the specified type. If no type
+is specified then all connections are returned. In scalar context the
+number of cached connections of the specified type is returned.
+
+=back
+
+
+The following methods are called by low-level protocol modules to
+try to save away connections and to get them back.
+
+=over
+
+=item $cache->deposit($type, $key, $conn)
+
+This method adds a new connection to the cache. As a result other
+already cached connections might be dropped. Multiple connections with
+the same $type/$key might added.
+
+=item $conn = $cache->withdraw($type, $key)
+
+This method tries to fetch back a connection that was previously
+deposited. If no cached connection with the specified $type/$key is
+found, then C<undef> is returned. There is not guarantee that a
+deposited connection can be withdrawn, as the cache manger is free to
+drop connections at any time.
+
+=back
+
+The following methods are called internally. Subclasses might want to
+override them.
+
+=over
+
+=item $conn->enforce_limits([$type])
+
+This method is called with after a new connection is added (deposited)
+in the cache or capacity limits are adjusted. The default
+implementation drops connections until the specified capacity limits
+are not exceeded.
+
+=item $conn->dropping($conn_record, $reason)
+
+This method is called when a connection is dropped. The record
+belonging to the dropped connection is passed as the first argument
+and a string describing the reason for the drop is passed as the
+second argument. The default implementation makes some noise if the
+$LWP::ConnCache::DEBUG variable is set and nothing more.
+
+=back
+
+=head1 SUBCLASSING
+
+For specialized cache policy it makes sense to subclass
+C<LWP::ConnCache> and perhaps override the deposit(), enforce_limits()
+and dropping() methods.
+
+The object itself is a hash. Keys prefixed with C<cc_> are reserved
+for the base class.

+=head1 NAME
+
+LWP::Debug - deprecated
+
+=head1 DESCRIPTION
+
+LWP::Debug used to provide tracing facilities, but these are not used
+by LWP any more. The code in this module is kept around
+(undocumented) so that 3rd party code that happen to use the old
+interfaces continue to run.
+
+One useful feature that LWP::Debug provided (in an imprecise and
+troublesome way) was network traffic monitoring. The following
+section provide some hints about recommened replacements.
+
+=head2 Network traffic monitoring
+
+The best way to monitor the network traffic that LWP generates is to
+use an external TCP monitoring program. The Wireshark program
+(L<http://www.wireshark.org/>) is higly recommended for this.
+
+Another approach it to use a debugging HTTP proxy server and make
+LWP direct all its traffic via this one. Call C<< $ua->proxy >> to
+set it up and then just use LWP as before.
+
+For less precise monitoring needs just setting up a few simple
+handlers might do. The following example sets up handlers to dump the
+request and response objects that pass through LWP:
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable());
+
+ $ua->add_handler("request_send", sub { shift->dump; return });
+ $ua->add_handler("response_done", sub { shift->dump; return });
+
+ $ua->get("http://www.example.com");

+
+LWP::MediaTypes - guess media type for a file or a URL
+
+=head1 SYNOPSIS
+
+ use LWP::MediaTypes qw(guess_media_type);
+ $type = guess_media_type("/tmp/foo.gif");
+
+=head1 DESCRIPTION
+
+This module provides functions for handling media (also known as
+MIME) types and encodings. The mapping from file extensions to media
+types is defined by the F<media.types> file. If the F<~/.media.types>
+file exists it is used instead.
+For backwards compatibility we will also look for F<~/.mime.types>.
+
+The following functions are exported by default:
+
+=over 4
+
+=item guess_media_type( $filename )
+
+=item guess_media_type( $uri )
+
+=item guess_media_type( $filename_or_uri, $header_to_modify )
+
+This function tries to guess media type and encoding for a file or a URI.
+It returns the content type, which is a string like C<"text/html">.
+In array context it also returns any content encodings applied (in the
+order used to encode the file). You can pass a URI object
+reference, instead of the file name.
+
+If the type can not be deduced from looking at the file name,
+then guess_media_type() will let the C<-T> Perl operator take a look.
+If this works (and C<-T> returns a TRUE value) then we return
+I<text/plain> as the type, otherwise we return
+I<application/octet-stream> as the type.
+
+The optional second argument should be a reference to a HTTP::Headers
+object or any object that implements the $obj->header method in a
+similar way. When it is present the values of the
+'Content-Type' and 'Content-Encoding' will be set for this header.
+
+=item media_suffix( $type, ... )
+
+This function will return all suffixes that can be used to denote the
+specified media type(s). Wildcard types can be used. In a scalar
+context it will return the first suffix found. Examples:
+
+ @suffixes = media_suffix('image/*', 'audio/basic');
+ $suffix = media_suffix('text/html');
+
+=back
+
+The following functions are only exported by explicit request:
+
+=over 4
+
+=item add_type( $type, @exts )
+
+Associate a list of file extensions with the given media type.
+Example:
+
+ add_type("x-world/x-vrml" => qw(wrl vrml));
+
+=item add_encoding( $type, @ext )
+
+Associate a list of file extensions with an encoding type.
+Example:
+
+ add_encoding("x-gzip" => "gz");
+
+=item read_media_types( @files )
+
+Parse media types files and add the type mappings found there.
+Example:
+
+ read_media_types("conf/mime.types");

+LWP::Protocol - Base class for LWP protocols
+
+=head1 SYNOPSIS
+
+ package LWP::Protocol::foo;
+ require LWP::Protocol;
+ @ISA=qw(LWP::Protocol);
+
+=head1 DESCRIPTION
+
+This class is used a the base class for all protocol implementations
+supported by the LWP library.
+
+When creating an instance of this class using
+C<LWP::Protocol::create($url)>, and you get an initialised subclass
+appropriate for that access method. In other words, the
+LWP::Protocol::create() function calls the constructor for one of its
+subclasses.
+
+All derived LWP::Protocol classes need to override the request()
+method which is used to service a request. The overridden method can
+make use of the collect() function to collect together chunks of data
+as it is received.
+
+The following methods and functions are provided:
+
+=over 4
+
+=item $prot = LWP::Protocol->new()
+
+The LWP::Protocol constructor is inherited by subclasses. As this is a
+virtual base class this method should B<not> be called directly.
+
+=item $prot = LWP::Protocol::create($scheme)
+
+Create an object of the class implementing the protocol to handle the
+given scheme. This is a function, not a method. It is more an object
+factory than a constructor. This is the function user agents should
+use to access protocols.
+
+=item $class = LWP::Protocol::implementor($scheme, [$class])
+
+Get and/or set implementor class for a scheme. Returns '' if the
+specified scheme is not supported.
+
+=item $prot->request(...)
+
+ $response = $protocol->request($request, $proxy, undef);
+ $response = $protocol->request($request, $proxy, '/tmp/sss');
+ $response = $protocol->request($request, $proxy, \&callback, 1024);
+
+Dispatches a request over the protocol, and returns a response
+object. This method needs to be overridden in subclasses. Refer to
+L<LWP::UserAgent> for description of the arguments.
+
+=item $prot->collect($arg, $response, $collector)
+
+Called to collect the content of a request, and process it
+appropriately into a scalar, file, or by calling a callback. If $arg
+is undefined, then the content is stored within the $response. If
+$arg is a simple scalar, then $arg is interpreted as a file name and
+the content is written to this file. If $arg is a reference to a
+routine, then content is passed to this routine.
+
+The $collector is a routine that will be called and which is
+responsible for returning pieces (as ref to scalar) of the content to
+process. The $collector signals EOF by returning a reference to an
+empty sting.
+
+The return value from collect() is the $response object reference.
+
+B<Note:> We will only use the callback or file argument if
+$response->is_success(). This avoids sending content data for
+redirects and authentication responses to the callback which would be
+confusing.
+
+=item $prot->collect_once($arg, $response, $content)
+
+Can be called when the whole response content is available as
+$content. This will invoke collect() with a collector callback that
+returns a reference to $content the first time and an empty string the
+next.

+# This is what RFC 1738 has to say about FTP access:
+# --------------------------------------------------
+#
+# 3.2. FTP
+#
+# The FTP URL scheme is used to designate files and directories on
+# Internet hosts accessible using the FTP protocol (RFC959).
+#
+# A FTP URL follow the syntax described in Section 3.1. If :<port> is
+# omitted, the port defaults to 21.
+#
+# 3.2.1. FTP Name and Password
+#
+# A user name and password may be supplied; they are used in the ftp
+# "USER" and "PASS" commands after first making the connection to the
+# FTP server. If no user name or password is supplied and one is
+# requested by the FTP server, the conventions for "anonymous" FTP are
+# to be used, as follows:
+#
+# The user name "anonymous" is supplied.
+#
+# The password is supplied as the Internet e-mail address
+# of the end user accessing the resource.
+#
+# If the URL supplies a user name but no password, and the remote
+# server requests a password, the program interpreting the FTP URL
+# should request one from the user.
+#
+# 3.2.2. FTP url-path
+#
+# The url-path of a FTP URL has the following syntax:
+#
+# <cwd1>/<cwd2>/.../<cwdN>/<name>;type=<typecode>
+#
+# Where <cwd1> through <cwdN> and <name> are (possibly encoded) strings
+# and <typecode> is one of the characters "a", "i", or "d". The part
+# ";type=<typecode>" may be omitted. The <cwdx> and <name> parts may be
+# empty. The whole url-path may be omitted, including the "/"
+# delimiting it from the prefix containing user, password, host, and
+# port.
+#
+# The url-path is interpreted as a series of FTP commands as follows:
+#
+# Each of the <cwd> elements is to be supplied, sequentially, as the
+# argument to a CWD (change working directory) command.
+#
+# If the typecode is "d", perform a NLST (name list) command with
+# <name> as the argument, and interpret the results as a file
+# directory listing.
+#
+# Otherwise, perform a TYPE command with <typecode> as the argument,
+# and then access the file whose name is <name> (for example, using
+# the RETR command.)
+#
+# Within a name or CWD component, the characters "/" and ";" are
+# reserved and must be encoded. The components are decoded prior to
+# their use in the FTP protocol. In particular, if the appropriate FTP
+# sequence to access a particular file requires supplying a string
+# containing a "/" as an argument to a CWD or RETR command, it is
+# necessary to encode each "/".
+#
+# For example, the URL <URL:ftp://myname@host.dom/%2Fetc/motd> is
+# interpreted by FTP-ing to "host.dom", logging in as "myname"
+# (prompting for a password if it is asked for), and then executing
+# "CWD /etc" and then "RETR motd". This has a different meaning from
+# <URL:ftp://myname@host.dom/etc/motd> which would "CWD etc" and then
+# "RETR motd"; the initial "CWD" might be executed relative to the
+# default directory for "myname". On the other hand,
+# <URL:ftp://myname@host.dom//etc/motd>, would "CWD " with a null
+# argument, then "CWD etc", and then "RETR motd".
+#
+# FTP URLs may also be used for other operations; for example, it is
+# possible to update a file on a remote file server, or infer
+# information about it from the directory listings. The mechanism for
+# doing so is not spelled out here.
+#
+# 3.2.3. FTP Typecode is Optional
+#
+# The entire ;type=<typecode> part of a FTP URL is optional. If it is
+# omitted, the client program interpreting the URL must guess the
+# appropriate mode to use. In general, the data content type of a file
+# can only be guessed from the name, e.g., from the suffix of the name;
+# the appropriate type code to be used for transfer of the file can
+# then be deduced from the data content of the file.
+#
+# 3.2.4 Hierarchy
+#
+# For some file systems, the "/" used to denote the hierarchical
+# structure of the URL corresponds to the delimiter used to construct a
+# file name hierarchy, and thus, the filename will look similar to the
+# URL path. This does NOT mean that the URL is a Unix filename.
+#
+# 3.2.5. Optimization
+#
+# Clients accessing resources via FTP may employ additional heuristics
+# to optimize the interaction. For some FTP servers, for example, it
+# may be reasonable to keep the control connection open while accessing
+# multiple URLs from the same server. However, there is no common
+# hierarchical model to the FTP protocol, so if a directory change
+# command has been given, it is impossible in general to deduce what
+# sequence should be given to navigate to another directory for a
+# second retrieval, if the paths are different. The only reliable
+# algorithm is to disconnect and reestablish the control connection.

+=head1 NAME
+
+LWP::RobotUA - a class for well-behaved Web robots
+
+=head1 SYNOPSIS
+
+ use LWP::RobotUA;
+ my $ua = LWP::RobotUA->new('my-robot/0.1', 'me@foo.com');
+ $ua->delay(10); # be very nice -- max one hit every ten minutes!
+ ...
+
+ # Then just use it just like a normal LWP::UserAgent:
+ my $response = $ua->get('http://whatever.int/...');
+ ...
+
+=head1 DESCRIPTION
+
+This class implements a user agent that is suitable for robot
+applications. Robots should be nice to the servers they visit. They
+should consult the F</robots.txt> file to ensure that they are welcomed
+and they should not make requests too frequently.
+
+But before you consider writing a robot, take a look at
+<URL:http://www.robotstxt.org/>.
+
+When you use a I<LWP::RobotUA> object as your user agent, then you do not
+really have to think about these things yourself; C<robots.txt> files
+are automatically consulted and obeyed, the server isn't queried
+too rapidly, and so on. Just send requests
+as you do when you are using a normal I<LWP::UserAgent>
+object (using C<< $ua->get(...) >>, C<< $ua->head(...) >>,
+C<< $ua->request(...) >>, etc.), and this
+special agent will make sure you are nice.
+
+=head1 METHODS
+
+The LWP::RobotUA is a sub-class of LWP::UserAgent and implements the
+same methods. In addition the following methods are provided:
+
+=over 4
+
+=item $ua = LWP::RobotUA->new( %options )
+
+=item $ua = LWP::RobotUA->new( $agent, $from )
+
+=item $ua = LWP::RobotUA->new( $agent, $from, $rules )
+
+The LWP::UserAgent options C<agent> and C<from> are mandatory. The
+options C<delay>, C<use_sleep> and C<rules> initialize attributes
+private to the RobotUA. If C<rules> are not provided, then
+C<WWW::RobotRules> is instantiated providing an internal database of
+F<robots.txt>.
+
+It is also possible to just pass the value of C<agent>, C<from> and
+optionally C<rules> as plain positional arguments.
+
+=item $ua->delay
+
+=item $ua->delay( $minutes )
+
+Get/set the minimum delay between requests to the same server, in
+I<minutes>. The default is 1 minute. Note that this number doesn't
+have to be an integer; for example, this sets the delay to 10 seconds:
+
+ $ua->delay(10/60);
+
+=item $ua->use_sleep
+
+=item $ua->use_sleep( $boolean )
+
+Get/set a value indicating whether the UA should sleep() if requests
+arrive too fast, defined as $ua->delay minutes not passed since
+last request to the given server. The default is TRUE. If this value is
+FALSE then an internal SERVICE_UNAVAILABLE response will be generated.
+It will have an Retry-After header that indicates when it is OK to
+send another request to this server.
+
+=item $ua->rules
+
+=item $ua->rules( $rules )
+
+Set/get which I<WWW::RobotRules> object to use.
+
+=item $ua->no_visits( $netloc )
+
+Returns the number of documents fetched from this server host. Yeah I
+know, this method should probably have been named num_visits() or
+something like that. :-(
+
+=item $ua->host_wait( $netloc )
+
+Returns the number of I<seconds> (from now) you must wait before you can
+make a new request to this host.
+
+=item $ua->as_string
+
+Returns a string that describes the state of the UA.
+Mainly useful for debugging.

+=head1 NAME
+
+LWP::Simple - simple procedural interface to LWP
+
+=head1 SYNOPSIS
+
+ perl -MLWP::Simple -e 'getprint "http://www.sn.no"'
+
+ use LWP::Simple;
+ $content = get("http://www.sn.no/");
+ die "Couldn't get it!" unless defined $content;
+
+ if (mirror("http://www.sn.no/", "foo") == RC_NOT_MODIFIED) {
+ ...
+ }
+
+ if (is_success(getprint("http://www.sn.no/"))) {
+ ...
+ }
+
+=head1 DESCRIPTION
+
+This module is meant for people who want a simplified view of the
+libwww-perl library. It should also be suitable for one-liners. If
+you need more control or access to the header fields in the requests
+sent and responses received, then you should use the full object-oriented
+interface provided by the C<LWP::UserAgent> module.
+
+The following functions are provided (and exported) by this module:
+
+=over 3
+
+=item get($url)
+
+The get() function will fetch the document identified by the given URL
+and return it. It returns C<undef> if it fails. The $url argument can
+be either a string or a reference to a URI object.
+
+You will not be able to examine the response code or response headers
+(like 'Content-Type') when you are accessing the web using this
+function. If you need that information you should use the full OO
+interface (see L<LWP::UserAgent>).
+
+=item head($url)
+
+Get document headers. Returns the following 5 values if successful:
+($content_type, $document_length, $modified_time, $expires, $server)
+
+Returns an empty list if it fails. In scalar context returns TRUE if
+successful.
+
+=item getprint($url)
+
+Get and print a document identified by a URL. The document is printed
+to the selected default filehandle for output (normally STDOUT) as
+data is received from the network. If the request fails, then the
+status code and message are printed on STDERR. The return value is
+the HTTP response code.
+
+=item getstore($url, $file)
+
+Gets a document identified by a URL and stores it in the file. The
+return value is the HTTP response code.
+
+=item mirror($url, $file)
+
+Get and store a document identified by a URL, using
+I<If-modified-since>, and checking the I<Content-Length>. Returns
+the HTTP response code.
+
+=back
+
+This module also exports the HTTP::Status constants and procedures.
+You can use them when you check the response code from getprint(),
+getstore() or mirror(). The constants are:
+
+ RC_CONTINUE
+ RC_SWITCHING_PROTOCOLS
+ RC_OK
+ RC_CREATED
+ RC_ACCEPTED
+ RC_NON_AUTHORITATIVE_INFORMATION
+ RC_NO_CONTENT
+ RC_RESET_CONTENT
+ RC_PARTIAL_CONTENT
+ RC_MULTIPLE_CHOICES
+ RC_MOVED_PERMANENTLY
+ RC_MOVED_TEMPORARILY
+ RC_SEE_OTHER
+ RC_NOT_MODIFIED
+ RC_USE_PROXY
+ RC_BAD_REQUEST
+ RC_UNAUTHORIZED
+ RC_PAYMENT_REQUIRED
+ RC_FORBIDDEN
+ RC_NOT_FOUND
+ RC_METHOD_NOT_ALLOWED
+ RC_NOT_ACCEPTABLE
+ RC_PROXY_AUTHENTICATION_REQUIRED
+ RC_REQUEST_TIMEOUT
+ RC_CONFLICT
+ RC_GONE
+ RC_LENGTH_REQUIRED
+ RC_PRECONDITION_FAILED
+ RC_REQUEST_ENTITY_TOO_LARGE
+ RC_REQUEST_URI_TOO_LARGE
+ RC_UNSUPPORTED_MEDIA_TYPE
+ RC_INTERNAL_SERVER_ERROR
+ RC_NOT_IMPLEMENTED
+ RC_BAD_GATEWAY
+ RC_SERVICE_UNAVAILABLE
+ RC_GATEWAY_TIMEOUT
+ RC_HTTP_VERSION_NOT_SUPPORTED
+
+The HTTP::Status classification functions are:
+
+=over 3
+
+=item is_success($rc)
+
+True if response code indicated a successful request.
+
+=item is_error($rc)
+
+True if response code indicated that an error occurred.
+
+=back
+
+The module will also export the LWP::UserAgent object as C<$ua> if you
+ask for it explicitly.
+
+The user agent created by this module will identify itself as
+"LWP::Simple/#.##"
+and will initialize its proxy defaults from the environment (by
+calling $ua->env_proxy).
+
+=head1 CAVEAT
+
+Note that if you are using both LWP::Simple and the very popular CGI.pm
+module, you may be importing a C<head> function from each module,
+producing a warning like "Prototype mismatch: sub main::head ($) vs
+none". Get around this problem by just not importing LWP::Simple's
+C<head> function, like so:
+
+ use LWP::Simple qw(!head);
+ use CGI qw(:standard); # then only CGI.pm defines a head()
+
+Then if you do need LWP::Simple's C<head> function, you can just call
+it as C<LWP::Simple::head($url)>.

+=head1 NAME
+
+LWP::UserAgent - Web user agent class
+
+=head1 SYNOPSIS
+
+ require LWP::UserAgent;
+
+ my $ua = LWP::UserAgent->new;
+ $ua->timeout(10);
+ $ua->env_proxy;
+
+ my $response = $ua->get('http://search.cpan.org/');
+
+ if ($response->is_success) {
+ print $response->decoded_content; # or whatever
+ }
+ else {
+ die $response->status_line;
+ }
+
+=head1 DESCRIPTION
+
+The C<LWP::UserAgent> is a class implementing a web user agent.
+C<LWP::UserAgent> objects can be used to dispatch web requests.
+
+In normal use the application creates an C<LWP::UserAgent> object, and
+then configures it with values for timeouts, proxies, name, etc. It
+then creates an instance of C<HTTP::Request> for the request that
+needs to be performed. This request is then passed to one of the
+request method the UserAgent, which dispatches it using the relevant
+protocol, and returns a C<HTTP::Response> object. There are
+convenience methods for sending the most common request types: get(),
+head() and post(). When using these methods then the creation of the
+request object is hidden as shown in the synopsis above.
+
+The basic approach of the library is to use HTTP style communication
+for all protocol schemes. This means that you will construct
+C<HTTP::Request> objects and receive C<HTTP::Response> objects even
+for non-HTTP resources like I<gopher> and I<ftp>. In order to achieve
+even more similarity to HTTP style communications, gopher menus and
+file directories are converted to HTML documents.
+
+=head1 CONSTRUCTOR METHODS
+
+The following constructor methods are available:
+
+=over 4
+
+=item $ua = LWP::UserAgent->new( %options )
+
+This method constructs a new C<LWP::UserAgent> object and returns it.
+Key/value pair arguments may be provided to set up the initial state.
+The following options correspond to attribute methods described below:
+
+ KEY DEFAULT
+ ----------- --------------------
+ agent "libwww-perl/#.###"
+ from undef
+ conn_cache undef
+ cookie_jar undef
+ default_headers HTTP::Headers->new
+ local_address undef
+ max_size undef
+ max_redirect 7
+ parse_head 1
+ protocols_allowed undef
+ protocols_forbidden undef
+ requests_redirectable ['GET', 'HEAD']
+ timeout 180
+
+The following additional options are also accepted: If the
+C<env_proxy> option is passed in with a TRUE value, then proxy
+settings are read from environment variables (see env_proxy() method
+below). If the C<keep_alive> option is passed in, then a
+C<LWP::ConnCache> is set up (see conn_cache() method below). The
+C<keep_alive> value is passed on as the C<total_capacity> for the
+connection cache.
+
+=item $ua->clone
+
+Returns a copy of the LWP::UserAgent object.
+
+=back
+
+=head1 ATTRIBUTES
+
+The settings of the configuration attributes modify the behaviour of the
+C<LWP::UserAgent> when it dispatches requests. Most of these can also
+be initialized by options passed to the constructor method.
+
+The following attribute methods are provided. The attribute value is
+left unchanged if no argument is given. The return value from each
+method is the old attribute value.
+
+=over
+
+=item $ua->agent
+
+=item $ua->agent( $product_id )
+
+Get/set the product token that is used to identify the user agent on
+the network. The agent value is sent as the "User-Agent" header in
+the requests. The default is the string returned by the _agent()
+method (see below).
+
+If the $product_id ends with space then the _agent() string is
+appended to it.
+
+The user agent string should be one or more simple product identifiers
+with an optional version number separated by the "/" character.
+Examples are:
+
+ $ua->agent('Checkbot/0.4 ' . $ua->_agent);
+ $ua->agent('Checkbot/0.4 '); # same as above
+ $ua->agent('Mozilla/5.0');
+ $ua->agent(""); # don't identify
+
+=item $ua->_agent
+
+Returns the default agent identifier. This is a string of the form
+"libwww-perl/#.###", where "#.###" is substituted with the version number
+of this library.
+
+=item $ua->from
+
+=item $ua->from( $email_address )
+
+Get/set the e-mail address for the human user who controls
+the requesting user agent. The address should be machine-usable, as
+defined in RFC 822. The C<from> value is send as the "From" header in
+the requests. Example:
+
+ $ua->from('gaas@cpan.org');
+
+The default is to not send a "From" header. See the default_headers()
+method for the more general interface that allow any header to be defaulted.
+
+=item $ua->cookie_jar
+
+=item $ua->cookie_jar( $cookie_jar_obj )
+
+Get/set the cookie jar object to use. The only requirement is that
+the cookie jar object must implement the extract_cookies($request) and
+add_cookie_header($response) methods. These methods will then be
+invoked by the user agent as requests are sent and responses are
+received. Normally this will be a C<HTTP::Cookies> object or some
+subclass.
+
+The default is to have no cookie_jar, i.e. never automatically add
+"Cookie" headers to the requests.
+
+Shortcut: If a reference to a plain hash is passed in as the
+$cookie_jar_object, then it is replaced with an instance of
+C<HTTP::Cookies> that is initialized based on the hash. This form also
+automatically loads the C<HTTP::Cookies> module. It means that:
+
+ $ua->cookie_jar({ file => "$ENV{HOME}/.cookies.txt" });
+
+is really just a shortcut for:
+
+ require HTTP::Cookies;
+ $ua->cookie_jar(HTTP::Cookies->new(file => "$ENV{HOME}/.cookies.txt"));
+
+=item $ua->default_headers
+
+=item $ua->default_headers( $headers_obj )
+
+Get/set the headers object that will provide default header values for
+any requests sent. By default this will be an empty C<HTTP::Headers>
+object.
+
+=item $ua->default_header( $field )
+
+=item $ua->default_header( $field => $value )
+
+This is just a short-cut for $ua->default_headers->header( $field =>
+$value ). Example:
+
+ $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable());
+ $ua->default_header('Accept-Language' => "no, en");
+
+=item $ua->conn_cache
+
+=item $ua->conn_cache( $cache_obj )
+
+Get/set the C<LWP::ConnCache> object to use. See L<LWP::ConnCache>
+for details.
+
+=item $ua->credentials( $netloc, $realm )
+
+=item $ua->credentials( $netloc, $realm, $uname, $pass )
+
+Get/set the user name and password to be used for a realm.
+
+The $netloc is a string of the form "<host>:<port>". The username and
+password will only be passed to this server. Example:
+
+ $ua->credentials("www.example.com:80", "Some Realm", "foo", "secret");
+
+=item $ua->local_address
+
+=item $ua->local_address( $address )
+
+Get/set the local interface to bind to for network connections. The interface
+can be specified as a hostname or an IP address. This value is passed as the
+C<LocalAddr> argument to L<IO::Socket::INET>.
+
+=item $ua->max_size
+
+=item $ua->max_size( $bytes )
+
+Get/set the size limit for response content. The default is C<undef>,
+which means that there is no limit. If the returned response content
+is only partial, because the size limit was exceeded, then a
+"Client-Aborted" header will be added to the response. The content
+might end up longer than C<max_size> as we abort once appending a
+chunk of data makes the length exceed the limit. The "Content-Length"
+header, if present, will indicate the length of the full content and
+will normally not be the same as C<< length($res->content) >>.
+
+=item $ua->max_redirect
+
+=item $ua->max_redirect( $n )
+
+This reads or sets the object's limit of how many times it will obey
+redirection responses in a given request cycle.
+
+By default, the value is 7. This means that if you call request()
+method and the response is a redirect elsewhere which is in turn a
+redirect, and so on seven times, then LWP gives up after that seventh
+request.
+
+=item $ua->parse_head
+
+=item $ua->parse_head( $boolean )
+
+Get/set a value indicating whether we should initialize response
+headers from the E<lt>head> section of HTML documents. The default is
+TRUE. Do not turn this off, unless you know what you are doing.
+
+=item $ua->protocols_allowed
+
+=item $ua->protocols_allowed( \@protocols )
+
+This reads (or sets) this user agent's list of protocols that the
+request methods will exclusively allow. The protocol names are case
+insensitive.
+
+For example: C<$ua-E<gt>protocols_allowed( [ 'http', 'https'] );>
+means that this user agent will I<allow only> those protocols,
+and attempts to use this user agent to access URLs with any other
+schemes (like "ftp://...") will result in a 500 error.
+
+To delete the list, call: C<$ua-E<gt>protocols_allowed(undef)>
+
+By default, an object has neither a C<protocols_allowed> list, nor a
+C<protocols_forbidden> list.
+
+Note that having a C<protocols_allowed> list causes any
+C<protocols_forbidden> list to be ignored.
+
+=item $ua->protocols_forbidden
+
+=item $ua->protocols_forbidden( \@protocols )
+
+This reads (or sets) this user agent's list of protocols that the
+request method will I<not> allow. The protocol names are case
+insensitive.
+
+For example: C<$ua-E<gt>protocols_forbidden( [ 'file', 'mailto'] );>
+means that this user agent will I<not> allow those protocols, and
+attempts to use this user agent to access URLs with those schemes
+will result in a 500 error.
+
+To delete the list, call: C<$ua-E<gt>protocols_forbidden(undef)>
+
+=item $ua->requests_redirectable
+
+=item $ua->requests_redirectable( \@requests )
+
+This reads or sets the object's list of request names that
+C<$ua-E<gt>redirect_ok(...)> will allow redirection for. By
+default, this is C<['GET', 'HEAD']>, as per RFC 2616. To
+change to include 'POST', consider:
+
+ push @{ $ua->requests_redirectable }, 'POST';
+
+=item $ua->show_progress
+
+=item $ua->show_progress( $boolean )
+
+Get/set a value indicating whether a progress bar should be displayed
+on on the terminal as requests are processed. The default is FALSE.
+
+=item $ua->timeout
+
+=item $ua->timeout( $secs )
+
+Get/set the timeout value in seconds. The default timeout() value is
+180 seconds, i.e. 3 minutes.
+
+The requests is aborted if no activity on the connection to the server
+is observed for C<timeout> seconds. This means that the time it takes
+for the complete transaction and the request() method to actually
+return might be longer.
+
+=back
+
+=head2 Proxy attributes
+
+The following methods set up when requests should be passed via a
+proxy server.
+
+=over
+
+=item $ua->proxy(\@schemes, $proxy_url)
+
+=item $ua->proxy($scheme, $proxy_url)
+
+Set/retrieve proxy URL for a scheme:
+
+ $ua->proxy(['http', 'ftp'], 'http://proxy.sn.no:8001/');
+ $ua->proxy('gopher', 'http://proxy.sn.no:8001/');
+
+The first form specifies that the URL is to be used for proxying of
+access methods listed in the list in the first method argument,
+i.e. 'http' and 'ftp'.
+
+The second form shows a shorthand form for specifying
+proxy URL for a single access scheme.
+
+=item $ua->no_proxy( $domain, ... )
+
+Do not proxy requests to the given domains. Calling no_proxy without
+any domains clears the list of domains. Eg:
+
+ $ua->no_proxy('localhost', 'example.com');
+
+=item $ua->env_proxy
+
+Load proxy settings from *_proxy environment variables. You might
+specify proxies like this (sh-syntax):
+
+ gopher_proxy=http://proxy.my.place/
+ wais_proxy=http://proxy.my.place/
+ no_proxy="localhost,example.com"
+ export gopher_proxy wais_proxy no_proxy
+
+csh or tcsh users should use the C<setenv> command to define these
+environment variables.
+
+On systems with case insensitive environment variables there exists a
+name clash between the CGI environment variables and the C<HTTP_PROXY>
+environment variable normally picked up by env_proxy(). Because of
+this C<HTTP_PROXY> is not honored for CGI scripts. The
+C<CGI_HTTP_PROXY> environment variable can be used instead.
+
+=back
+
+=head2 Handlers
+
+Handlers are code that injected at various phases during the
+processing of requests. The following methods are provided to manage
+the active handlers:
+
+=over
+
+=item $ua->add_handler( $phase => \&cb, %matchspec )
+
+Add handler to be invoked in the given processing phase. For how to
+specify %matchspec see L<HTTP::Config/"Matching">.
+
+The possible values $phase and the corresponding callback signatures are:
+
+=over
+
+=item request_preprepare => sub { my($request, $ua, $h) = @_; ... }
+
+The handler is called before the C<request_prepare> and other standard
+initialization of of the request. This can be used to set up headers
+and attributes that the C<request_prepare> handler depends on. Proxy
+initialization should take place here; but in general don't register
+handlers for this phase.
+
+=item request_prepare => sub { my($request, $ua, $h) = @_; ... }
+
+The handler is called before the request is sent and can modify the
+request any way it see fit. This can for instance be used to add
+certain headers to specific requests.
+
+The method can assign a new request object to $_[0] to replace the
+request that is sent fully.
+
+The return value from the callback is ignored. If an exceptions is
+raised it will abort the request and make the request method return a
+"400 Bad request" response.
+
+=item request_send => sub { my($request, $ua, $h) = @_; ... }
+
+This handler get a chance of handling requests before it's sent to the
+protocol handlers. It should return an HTTP::Response object if it
+wishes to terminate the processing; otherwise it should return nothing.
+
+The C<response_header> and C<response_data> handlers will not be
+invoked for this response, but the C<response_done> will be.
+
+=item response_header => sub { my($response, $ua, $h) = @_; ... }
+
+This handler is called right after the response headers have been
+received, but before any content data. The handler might set up
+handlers for data and might croak to abort the request.
+
+The handler might set the $response->{default_add_content} value to
+control if any received data should be added to the response object
+directly. This will initially be false if the $ua->request() method
+was called with a $content_file or $content_cb argument; otherwise true.
+
+=item response_data => sub { my($response, $ua, $h, $data) = @_; ... }
+
+This handlers is called for each chunk of data received for the
+response. The handler might croak to abort the request.
+
+This handler need to return a TRUE value to be called again for
+subsequent chunks for the same request.
+
+=item response_done => sub { my($response, $ua, $h) = @_; ... }
+
+The handler is called after the response has been fully received, but
+before any redirect handling is attempted. The handler can be used to
+extract information or modify the response.
+
+=item response_redirect => sub { my($response, $ua, $h) = @_; ... }
+
+The handler is called in $ua->request after C<response_done>. If the
+handler return an HTTP::Request object we'll start over with processing
+this request instead.
+
+=back
+
+=item $ua->remove_handler( undef, %matchspec )
+
+=item $ua->remove_handler( $phase, %matchspec )
+
+Remove handlers that match the given %matchspec. If $phase is not
+provided remove handlers from all phases.
+
+Be careful as calling this function with %matchspec that is not not
+specific enough can remove handlers not owned by you. It's probably
+better to use the set_my_handler() method instead.
+
+The removed handlers are returned.
+
+=item $ua->set_my_handler( $phase, $cb, %matchspec )
+
+Set handlers private to the executing subroutine. Works by defaulting
+an C<owner> field to the %matchspec that holds the name of the called
+subroutine. You might pass an explicit C<owner> to override this.
+
+If $cb is passed as C<undef>, remove the handler.
+
+=item $ua->get_my_handler( $phase, %matchspec )
+
+=item $ua->get_my_handler( $phase, %matchspec, $init )
+
+Will retrieve the matching handler as hash ref.
+
+If C<$init> is passed passed as a TRUE value, create and add the
+handler if it's not found. If $init is a subroutine reference, then
+it's called with the created handler hash as argument. This sub might
+populate the hash with extra fields; especially the callback. If
+$init is a hash reference, merge the hashes.
+
+=item $ua->handlers( $phase, $request )
+
+=item $ua->handlers( $phase, $response )
+
+Returns the handlers that apply to the given request or response at
+the given processing phase.
+
+=back
+
+=head1 REQUEST METHODS
+
+The methods described in this section are used to dispatch requests
+via the user agent. The following request methods are provided:
+
+=over
+
+=item $ua->get( $url )
+
+=item $ua->get( $url , $field_name => $value, ... )
+
+This method will dispatch a C<GET> request on the given $url. Further
+arguments can be given to initialize the headers of the request. These
+are given as separate name/value pairs. The return value is a
+response object. See L<HTTP::Response> for a description of the
+interface it provides.
+
+There will still be a response object returned when LWP can't connect to the
+server specified in the URL or when other failures in protocol handlers occur.
+These internal responses use the standard HTTP status codes, so the responses
+can't be differentiated by testing the response status code alone. Error
+responses that LWP generates internally will have the "Client-Warning" header
+set to the value "Internal response". If you need to differentiate these
+internal responses from responses that a remote server actually generates, you
+need to test this header value.
+
+Fields names that start with ":" are special. These will not
+initialize headers of the request but will determine how the response
+content is treated. The following special field names are recognized:
+
+ :content_file => $filename
+ :content_cb => \&callback
+ :read_size_hint => $bytes
+
+If a $filename is provided with the C<:content_file> option, then the
+response content will be saved here instead of in the response
+object. If a callback is provided with the C<:content_cb> option then
+this function will be called for each chunk of the response content as
+it is received from the server. If neither of these options are
+given, then the response content will accumulate in the response
+object itself. This might not be suitable for very large response
+bodies. Only one of C<:content_file> or C<:content_cb> can be
+specified. The content of unsuccessful responses will always
+accumulate in the response object itself, regardless of the
+C<:content_file> or C<:content_cb> options passed in.
+
+The C<:read_size_hint> option is passed to the protocol module which
+will try to read data from the server in chunks of this size. A
+smaller value for the C<:read_size_hint> will result in a higher
+number of callback invocations.
+
+The callback function is called with 3 arguments: a chunk of data, a
+reference to the response object, and a reference to the protocol
+object. The callback can abort the request by invoking die(). The
+exception message will show up as the "X-Died" header field in the
+response returned by the get() function.
+
+=item $ua->head( $url )
+
+=item $ua->head( $url , $field_name => $value, ... )
+
+This method will dispatch a C<HEAD> request on the given $url.
+Otherwise it works like the get() method described above.
+
+=item $ua->post( $url, \%form )
+
+=item $ua->post( $url, \@form )
+
+=item $ua->post( $url, \%form, $field_name => $value, ... )
+
+=item $ua->post( $url, $field_name => $value,... Content => \%form )
+
+=item $ua->post( $url, $field_name => $value,... Content => \@form )
+
+=item $ua->post( $url, $field_name => $value,... Content => $content )
+
+This method will dispatch a C<POST> request on the given $url, with
+%form or @form providing the key/value pairs for the fill-in form
+content. Additional headers and content options are the same as for
+the get() method.
+
+This method will use the POST() function from C<HTTP::Request::Common>
+to build the request. See L<HTTP::Request::Common> for a details on
+how to pass form content and other advanced features.
+
+=item $ua->mirror( $url, $filename )
+
+This method will get the document identified by $url and store it in
+file called $filename. If the file already exists, then the request
+will contain an "If-Modified-Since" header matching the modification
+time of the file. If the document on the server has not changed since
+this time, then nothing happens. If the document has been updated, it
+will be downloaded again. The modification time of the file will be
+forced to match that of the server.
+
+The return value is the the response object.
+
+=item $ua->request( $request )
+
+=item $ua->request( $request, $content_file )
+
+=item $ua->request( $request, $content_cb )
+
+=item $ua->request( $request, $content_cb, $read_size_hint )
+
+This method will dispatch the given $request object. Normally this
+will be an instance of the C<HTTP::Request> class, but any object with
+a similar interface will do. The return value is a response object.
+See L<HTTP::Request> and L<HTTP::Response> for a description of the
+interface provided by these classes.
+
+The request() method will process redirects and authentication
+responses transparently. This means that it may actually send several
+simple requests via the simple_request() method described below.
+
+The request methods described above; get(), head(), post() and
+mirror(), will all dispatch the request they build via this method.
+They are convenience methods that simply hides the creation of the
+request object for you.
+
+The $content_file, $content_cb and $read_size_hint all correspond to
+options described with the get() method above.
+
+You are allowed to use a CODE reference as C<content> in the request
+object passed in. The C<content> function should return the content
+when called. The content can be returned in chunks. The content
+function will be invoked repeatedly until it return an empty string to
+signal that there is no more content.
+
+=item $ua->simple_request( $request )
+
+=item $ua->simple_request( $request, $content_file )
+
+=item $ua->simple_request( $request, $content_cb )
+
+=item $ua->simple_request( $request, $content_cb, $read_size_hint )
+
+This method dispatches a single request and returns the response
+received. Arguments are the same as for request() described above.
+
+The difference from request() is that simple_request() will not try to
+handle redirects or authentication responses. The request() method
+will in fact invoke this method for each simple request it sends.
+
+=item $ua->is_protocol_supported( $scheme )
+
+You can use this method to test whether this user agent object supports the
+specified C<scheme>. (The C<scheme> might be a string (like 'http' or
+'ftp') or it might be an URI object reference.)
+
+Whether a scheme is supported, is determined by the user agent's
+C<protocols_allowed> or C<protocols_forbidden> lists (if any), and by
+the capabilities of LWP. I.e., this will return TRUE only if LWP
+supports this protocol I<and> it's permitted for this particular
+object.
+
+=back
+
+=head2 Callback methods
+
+The following methods will be invoked as requests are processed. These
+methods are documented here because subclasses of C<LWP::UserAgent>
+might want to override their behaviour.
+
+=over
+
+=item $ua->prepare_request( $request )
+
+This method is invoked by simple_request(). Its task is to modify the
+given $request object by setting up various headers based on the
+attributes of the user agent. The return value should normally be the
+$request object passed in. If a different request object is returned
+it will be the one actually processed.
+
+The headers affected by the base implementation are; "User-Agent",
+"From", "Range" and "Cookie".
+
+=item $ua->redirect_ok( $prospective_request, $response )
+
+This method is called by request() before it tries to follow a
+redirection to the request in $response. This should return a TRUE
+value if this redirection is permissible. The $prospective_request
+will be the request to be sent if this method returns TRUE.
+
+The base implementation will return FALSE unless the method
+is in the object's C<requests_redirectable> list,
+FALSE if the proposed redirection is to a "file://..."
+URL, and TRUE otherwise.
+
+=item $ua->get_basic_credentials( $realm, $uri, $isproxy )
+
+This is called by request() to retrieve credentials for documents
+protected by Basic or Digest Authentication. The arguments passed in
+is the $realm provided by the server, the $uri requested and a boolean
+flag to indicate if this is authentication against a proxy server.
+
+The method should return a username and password. It should return an
+empty list to abort the authentication resolution attempt. Subclasses
+can override this method to prompt the user for the information. An
+example of this can be found in C<lwp-request> program distributed
+with this library.
+
+The base implementation simply checks a set of pre-stored member
+variables, set up with the credentials() method.
+
+=item $ua->progress( $status, $request_or_response )
+
+This is called frequently as the response is received regardless of
+how the content is processed. The method is called with $status
+"begin" at the start of processing the request and with $state "end"
+before the request method returns. In between these $status will be
+the fraction of the response currently received or the string "tick"
+if the fraction can't be calculated.
+
+When $status is "begin" the second argument is the request object,
+otherwise it is the response object.

+
+=head1 DESCRIPTION
+
+The C<Net::HTTP> class is a low-level HTTP client. An instance of the
+C<Net::HTTP> class represents a connection to an HTTP server. The
+HTTP protocol is described in RFC 2616. The C<Net::HTTP> class
+supports C<HTTP/1.0> and C<HTTP/1.1>.
+
+C<Net::HTTP> is a sub-class of C<IO::Socket::INET>. You can mix the
+methods described below with reading and writing from the socket
+directly. This is not necessary a good idea, unless you know what you
+are doing.
+
+The following methods are provided (in addition to those of
+C<IO::Socket::INET>):
+
+=over
+
+=item $s = Net::HTTP->new( %options )
+
+The C<Net::HTTP> constructor method takes the same options as
+C<IO::Socket::INET>'s as well as these:
+
+ Host: Initial host attribute value
+ KeepAlive: Initial keep_alive attribute value
+ SendTE: Initial send_te attribute_value
+ HTTPVersion: Initial http_version attribute value
+ PeerHTTPVersion: Initial peer_http_version attribute value
+ MaxLineLength: Initial max_line_length attribute value
+ MaxHeaderLines: Initial max_header_lines attribute value
+
+The C<Host> option is also the default for C<IO::Socket::INET>'s
+C<PeerAddr>. The C<PeerPort> defaults to 80 if not provided.
+
+The C<Listen> option provided by C<IO::Socket::INET>'s constructor
+method is not allowed.
+
+If unable to connect to the given HTTP server then the constructor
+returns C<undef> and $@ contains the reason. After a successful
+connect, a C<Net:HTTP> object is returned.
+
+=item $s->host
+
+Get/set the default value of the C<Host> header to send. The $host
+must not be set to an empty string (or C<undef>) for HTTP/1.1.
+
+=item $s->keep_alive
+
+Get/set the I<keep-alive> value. If this value is TRUE then the
+request will be sent with headers indicating that the server should try
+to keep the connection open so that multiple requests can be sent.
+
+The actual headers set will depend on the value of the C<http_version>
+and C<peer_http_version> attributes.
+
+=item $s->send_te
+
+Get/set the a value indicating if the request will be sent with a "TE"
+header to indicate the transfer encodings that the server can choose to
+use. The list of encodings announced as accepted by this client depends
+on availability of the following modules: C<Compress::Raw::Zlib> for
+I<deflate>, and C<IO::Compress::Gunzip> for I<gzip>.
+
+=item $s->http_version
+
+Get/set the HTTP version number that this client should announce.
+This value can only be set to "1.0" or "1.1". The default is "1.1".
+
+=item $s->peer_http_version
+
+Get/set the protocol version number of our peer. This value will
+initially be "1.0", but will be updated by a successful
+read_response_headers() method call.
+
+=item $s->max_line_length
+
+Get/set a limit on the length of response line and response header
+lines. The default is 8192. A value of 0 means no limit.
+
+=item $s->max_header_length
+
+Get/set a limit on the number of header lines that a response can
+have. The default is 128. A value of 0 means no limit.
+
+=item $s->format_request($method, $uri, %headers, [$content])
+
+Format a request message and return it as a string. If the headers do
+not include a C<Host> header, then a header is inserted with the value
+of the C<host> attribute. Headers like C<Connection> and
+C<Keep-Alive> might also be added depending on the status of the
+C<keep_alive> attribute.
+
+If $content is given (and it is non-empty), then a C<Content-Length>
+header is automatically added unless it was already present.
+
+=item $s->write_request($method, $uri, %headers, [$content])
+
+Format and send a request message. Arguments are the same as for
+format_request(). Returns true if successful.
+
+=item $s->format_chunk( $data )
+
+Returns the string to be written for the given chunk of data.
+
+=item $s->write_chunk($data)
+
+Will write a new chunk of request entity body data. This method
+should only be used if the C<Transfer-Encoding> header with a value of
+C<chunked> was sent in the request. Note, writing zero-length data is
+a no-op. Use the write_chunk_eof() method to signal end of entity
+body data.
+
+Returns true if successful.
+
+=item $s->format_chunk_eof( %trailers )
+
+Returns the string to be written for signaling EOF when a
+C<Transfer-Encoding> of C<chunked> is used.
+
+=item $s->write_chunk_eof( %trailers )
+
+Will write eof marker for chunked data and optional trailers. Note
+that trailers should not really be used unless is was signaled
+with a C<Trailer> header.
+
+Returns true if successful.
+
+=item ($code, $mess, %headers) = $s->read_response_headers( %opts )
+
+Read response headers from server and return it. The $code is the 3
+digit HTTP status code (see L<HTTP::Status>) and $mess is the textual
+message that came with it. Headers are then returned as key/value
+pairs. Since key letter casing is not normalized and the same key can
+even occur multiple times, assigning these values directly to a hash
+is not wise. Only the $code is returned if this method is called in
+scalar context.
+
+As a side effect this method updates the 'peer_http_version'
+attribute.
+
+Options might be passed in as key/value pairs. There are currently
+only two options supported; C<laxed> and C<junk_out>.
+
+The C<laxed> option will make read_response_headers() more forgiving
+towards servers that have not learned how to speak HTTP properly. The
+C<laxed> option is a boolean flag, and is enabled by passing in a TRUE
+value. The C<junk_out> option can be used to capture bad header lines
+when C<laxed> is enabled. The value should be an array reference.
+Bad header lines will be pushed onto the array.
+
+The C<laxed> option must be specified in order to communicate with
+pre-HTTP/1.0 servers that don't describe the response outcome or the
+data they send back with a header block. For these servers
+peer_http_version is set to "0.9" and this method returns (200,
+"Assumed OK").
+
+The method will raise an exception (die) if the server does not speak
+proper HTTP or if the C<max_line_length> or C<max_header_length>
+limits are reached. If the C<laxed> option is turned on and
+C<max_line_length> and C<max_header_length> checks are turned off,
+then no exception will be raised and this method will always
+return a response code.
+
+=item $n = $s->read_entity_body($buf, $size);
+
+Reads chunks of the entity body content. Basically the same interface
+as for read() and sysread(), but the buffer offset argument is not
+supported yet. This method should only be called after a successful
+read_response_headers() call.
+
+The return value will be C<undef> on read errors, 0 on EOF, -1 if no data
+could be returned this time, otherwise the number of bytes assigned
+to $buf. The $buf is set to "" when the return value is -1.
+
+You normally want to retry this call if this function returns either
+-1 or C<undef> with C<$!> as EINTR or EAGAIN (see L<Errno>). EINTR
+can happen if the application catches signals and EAGAIN can happen if
+you made the socket non-blocking.
+
+This method will raise exceptions (die) if the server does not speak
+proper HTTP. This can only happen when reading chunked data.
+
+=item %headers = $s->get_trailers
+
+After read_entity_body() has returned 0 to indicate end of the entity
+body, you might call this method to pick up any trailers.
+
+=item $s->_rbuf
+
+Get/set the read buffer content. The read_response_headers() and
+read_entity_body() methods use an internal buffer which they will look
+for data before they actually sysread more from the socket itself. If
+they read too much, the remaining data will be left in this buffer.
+
+=item $s->_rbuf_length
+
+Returns the number of bytes in the read buffer. This should always be
+the same as:
+
+ length($s->_rbuf)
+
+but might be more efficient.
+
+=back
+
+=head1 SUBCLASSING
+
+The read_response_headers() and read_entity_body() will invoke the
+sysread() method when they need more data. Subclasses might want to
+override this method to control how reading takes place.
+
+The object itself is a glob. Subclasses should avoid using hash key
+names prefixed with C<http_> and C<io_>.

+=head1 NAME
+
+Net::HTTP::NB - Non-blocking HTTP client
+
+=head1 SYNOPSIS
+
+ use Net::HTTP::NB;
+ my $s = Net::HTTP::NB->new(Host => "www.perl.com") || die $@;
+ $s->write_request(GET => "/");
+
+ use IO::Select;
+ my $sel = IO::Select->new($s);
+
+ READ_HEADER: {
+ die "Header timeout" unless $sel->can_read(10);
+ my($code, $mess, %h) = $s->read_response_headers;
+ redo READ_HEADER unless $code;
+ }

+ my $buf;
+ my $n = $s->read_entity_body($buf, 1024);
+ last unless $n;
+ print $buf;
+ }
+
+=head1 DESCRIPTION
+
+Same interface as C<Net::HTTP> but it will never try multiple reads
+when the read_response_headers() or read_entity_body() methods are
+invoked. This make it possible to multiplex multiple Net::HTTP::NB
+using select without risk blocking.
+
+If read_response_headers() did not see enough data to complete the
+headers an empty list is returned.
+
+If read_entity_body() did not see new entity data in its read
+the value -1 is returned.

+
+=head1 DESCRIPTION
+
+This module implements the C<URI> class. Objects of this class
+represent "Uniform Resource Identifier references" as specified in RFC
+2396 (and updated by RFC 2732).
+
+A Uniform Resource Identifier is a compact string of characters that
+identifies an abstract or physical resource. A Uniform Resource
+Identifier can be further classified as either a Uniform Resource Locator
+(URL) or a Uniform Resource Name (URN). The distinction between URL
+and URN does not matter to the C<URI> class interface. A
+"URI-reference" is a URI that may have additional information attached
+in the form of a fragment identifier.
+
+An absolute URI reference consists of three parts: a I<scheme>, a
+I<scheme-specific part> and a I<fragment> identifier. A subset of URI
+references share a common syntax for hierarchical namespaces. For
+these, the scheme-specific part is further broken down into
+I<authority>, I<path> and I<query> components. These URIs can also
+take the form of relative URI references, where the scheme (and
+usually also the authority) component is missing, but implied by the
+context of the URI reference. The three forms of URI reference
+syntax are summarized as follows:
+
+ <scheme>:<scheme-specific-part>#<fragment>
+ <scheme>://<authority><path>?<query>#<fragment>
+ <path>?<query>#<fragment>
+
+The components into which a URI reference can be divided depend on the
+I<scheme>. The C<URI> class provides methods to get and set the
+individual components. The methods available for a specific
+C<URI> object depend on the scheme.
+
+=head1 CONSTRUCTORS
+
+The following methods construct new C<URI> objects:
+
+=over 4
+
+=item $uri = URI->new( $str )
+
+=item $uri = URI->new( $str, $scheme )
+
+Constructs a new URI object. The string
+representation of a URI is given as argument, together with an optional
+scheme specification. Common URI wrappers like "" and <>, as well as
+leading and trailing white space, are automatically removed from
+the $str argument before it is processed further.
+
+The constructor determines the scheme, maps this to an appropriate
+URI subclass, constructs a new object of that class and returns it.
+
+The $scheme argument is only used when $str is a
+relative URI. It can be either a simple string that
+denotes the scheme, a string containing an absolute URI reference, or
+an absolute C<URI> object. If no $scheme is specified for a relative
+URI $str, then $str is simply treated as a generic URI (no scheme-specific
+methods available).
+
+The set of characters available for building URI references is
+restricted (see L<URI::Escape>). Characters outside this set are
+automatically escaped by the URI constructor.
+
+=item $uri = URI->new_abs( $str, $base_uri )
+
+Constructs a new absolute URI object. The $str argument can
+denote a relative or absolute URI. If relative, then it is
+absolutized using $base_uri as base. The $base_uri must be an absolute
+URI.
+
+=item $uri = URI::file->new( $filename )
+
+=item $uri = URI::file->new( $filename, $os )
+
+Constructs a new I<file> URI from a file name. See L<URI::file>.
+
+=item $uri = URI::file->new_abs( $filename )
+
+=item $uri = URI::file->new_abs( $filename, $os )
+
+Constructs a new absolute I<file> URI from a file name. See
+L<URI::file>.
+
+=item $uri = URI::file->cwd
+
+Returns the current working directory as a I<file> URI. See
+L<URI::file>.
+
+=item $uri->clone
+
+Returns a copy of the $uri.
+
+=back
+
+=head1 COMMON METHODS
+
+The methods described in this section are available for all C<URI>
+objects.
+
+Methods that give access to components of a URI always return the
+old value of the component. The value returned is C<undef> if the
+component was not present. There is generally a difference between a
+component that is empty (represented as C<"">) and a component that is
+missing (represented as C<undef>). If an accessor method is given an
+argument, it updates the corresponding component in addition to
+returning the old value of the component. Passing an undefined
+argument removes the component (if possible). The description of
+each accessor method indicates whether the component is passed as
+an escaped or an unescaped string. A component that can be further
+divided into sub-parts are usually passed escaped, as unescaping might
+change its semantics.
+
+The common methods available for all URI are:
+
+=over 4
+
+=item $uri->scheme
+
+=item $uri->scheme( $new_scheme )
+
+Sets and returns the scheme part of the $uri. If the $uri is
+relative, then $uri->scheme returns C<undef>. If called with an
+argument, it updates the scheme of $uri, possibly changing the
+class of $uri, and returns the old scheme value. The method croaks
+if the new scheme name is illegal; a scheme name must begin with a
+letter and must consist of only US-ASCII letters, numbers, and a few
+special marks: ".", "+", "-". This restriction effectively means
+that the scheme must be passed unescaped. Passing an undefined
+argument to the scheme method makes the URI relative (if possible).
+
+Letter case does not matter for scheme names. The string
+returned by $uri->scheme is always lowercase. If you want the scheme
+just as it was written in the URI in its original case,
+you can use the $uri->_scheme method instead.
+
+=item $uri->opaque
+
+=item $uri->opaque( $new_opaque )
+
+Sets and returns the scheme-specific part of the $uri
+(everything between the scheme and the fragment)
+as an escaped string.
+
+=item $uri->path
+
+=item $uri->path( $new_path )
+
+Sets and returns the same value as $uri->opaque unless the URI
+supports the generic syntax for hierarchical namespaces.
+In that case the generic method is overridden to set and return
+the part of the URI between the I<host name> and the I<fragment>.
+
+=item $uri->fragment
+
+=item $uri->fragment( $new_frag )
+
+Returns the fragment identifier of a URI reference
+as an escaped string.
+
+=item $uri->as_string
+
+Returns a URI object to a plain ASCII string. URI objects are
+also converted to plain strings automatically by overloading. This
+means that $uri objects can be used as plain strings in most Perl
+constructs.
+
+=item $uri->as_iri
+
+Returns a Unicode string representing the URI. Escaped UTF-8 sequences
+representing non-ASCII characters are turned into their corresponding Unicode
+code point.
+
+=item $uri->canonical
+
+Returns a normalized version of the URI. The rules
+for normalization are scheme-dependent. They usually involve
+lowercasing the scheme and Internet host name components,
+removing the explicit port specification if it matches the default port,
+uppercasing all escape sequences, and unescaping octets that can be
+better represented as plain characters.
+
+For efficiency reasons, if the $uri is already in normalized form,
+then a reference to it is returned instead of a copy.
+
+=item $uri->eq( $other_uri )
+
+=item URI::eq( $first_uri, $other_uri )
+
+Tests whether two URI references are equal. URI references
+that normalize to the same string are considered equal. The method
+can also be used as a plain function which can also test two string
+arguments.
+
+If you need to test whether two C<URI> object references denote the
+same object, use the '==' operator.
+
+=item $uri->abs( $base_uri )
+
+Returns an absolute URI reference. If $uri is already
+absolute, then a reference to it is simply returned. If the $uri
+is relative, then a new absolute URI is constructed by combining the
+$uri and the $base_uri, and returned.
+
+=item $uri->rel( $base_uri )
+
+Returns a relative URI reference if it is possible to
+make one that denotes the same resource relative to $base_uri.
+If not, then $uri is simply returned.
+
+=item $uri->secure
+
+Returns a TRUE value if the URI is considered to point to a resource on
+a secure channel, such as an SSL or TLS encrypted one.
+
+=back
+
+=head1 GENERIC METHODS
+
+The following methods are available to schemes that use the
+common/generic syntax for hierarchical namespaces. The descriptions of
+schemes below indicate which these are. Unknown schemes are
+assumed to support the generic syntax, and therefore the following
+methods:
+
+=over 4
+
+=item $uri->authority
+
+=item $uri->authority( $new_authority )
+
+Sets and returns the escaped authority component
+of the $uri.
+
+=item $uri->path
+
+=item $uri->path( $new_path )
+
+Sets and returns the escaped path component of
+the $uri (the part between the host name and the query or fragment).
+The path can never be undefined, but it can be the empty string.
+
+=item $uri->path_query
+
+=item $uri->path_query( $new_path_query )
+
+Sets and returns the escaped path and query
+components as a single entity. The path and the query are
+separated by a "?" character, but the query can itself contain "?".
+
+=item $uri->path_segments
+
+=item $uri->path_segments( $segment, ... )
+
+Sets and returns the path. In a scalar context, it returns
+the same value as $uri->path. In a list context, it returns the
+unescaped path segments that make up the path. Path segments that
+have parameters are returned as an anonymous array. The first element
+is the unescaped path segment proper; subsequent elements are escaped
+parameter strings. Such an anonymous array uses overloading so it can
+be treated as a string too, but this string does not include the
+parameters.
+
+Note that absolute paths have the empty string as their first
+I<path_segment>, i.e. the I<path> C</foo/bar> have 3
+I<path_segments>; "", "foo" and "bar".
+
+=item $uri->query
+
+=item $uri->query( $new_query )
+
+Sets and returns the escaped query component of
+the $uri.
+
+=item $uri->query_form
+
+=item $uri->query_form( $key1 => $val1, $key2 => $val2, ... )
+
+=item $uri->query_form( $key1 => $val1, $key2 => $val2, ..., $delim )
+
+=item $uri->query_form( \@key_value_pairs )
+
+=item $uri->query_form( \@key_value_pairs, $delim )
+
+=item $uri->query_form( \%hash )
+
+=item $uri->query_form( \%hash, $delim )
+
+Sets and returns query components that use the
+I<application/x-www-form-urlencoded> format. Key/value pairs are
+separated by "&", and the key is separated from the value by a "="
+character.
+
+The form can be set either by passing separate key/value pairs, or via
+an array or hash reference. Passing an empty array or an empty hash
+removes the query component, whereas passing no arguments at all leaves
+the component unchanged. The order of keys is undefined if a hash
+reference is passed. The old value is always returned as a list of
+separate key/value pairs. Assigning this list to a hash is unwise as
+the keys returned might repeat.
+
+The values passed when setting the form can be plain strings or
+references to arrays of strings. Passing an array of values has the
+same effect as passing the key repeatedly with one value at a time.
+All the following statements have the same effect:
+
+ $uri->query_form(foo => 1, foo => 2);
+ $uri->query_form(foo => [1, 2]);
+ $uri->query_form([ foo => 1, foo => 2 ]);
+ $uri->query_form([ foo => [1, 2] ]);
+ $uri->query_form({ foo => [1, 2] });
+
+The $delim parameter can be passed as ";" to force the key/value pairs
+to be delimited by ";" instead of "&" in the query string. This
+practice is often recommended for URLs embedded in HTML or XML
+documents as this avoids the trouble of escaping the "&" character.
+You might also set the $URI::DEFAULT_QUERY_FORM_DELIMITER variable to
+";" for the same global effect.
+
+The C<URI::QueryParam> module can be loaded to add further methods to
+manipulate the form of a URI. See L<URI::QueryParam> for details.
+
+=item $uri->query_keywords
+
+=item $uri->query_keywords( $keywords, ... )
+
+=item $uri->query_keywords( \@keywords )
+
+Sets and returns query components that use the
+keywords separated by "+" format.
+
+The keywords can be set either by passing separate keywords directly
+or by passing a reference to an array of keywords. Passing an empty
+array removes the query component, whereas passing no arguments at
+all leaves the component unchanged. The old value is always returned
+as a list of separate words.
+
+=back
+
+=head1 SERVER METHODS
+
+For schemes where the I<authority> component denotes an Internet host,
+the following methods are available in addition to the generic
+methods.
+
+=over 4
+
+=item $uri->userinfo
+
+=item $uri->userinfo( $new_userinfo )
+
+Sets and returns the escaped userinfo part of the
+authority component.
+
+For some schemes this is a user name and a password separated by
+a colon. This practice is not recommended. Embedding passwords in
+clear text (such as URI) has proven to be a security risk in almost
+every case where it has been used.
+
+=item $uri->host
+
+=item $uri->host( $new_host )
+
+Sets and returns the unescaped hostname.
+
+If the $new_host string ends with a colon and a number, then this
+number also sets the port.
+
+For IPv6 addresses the brackets around the raw address is removed in the return
+value from $uri->host. When setting the host attribute to an IPv6 address you
+can use a raw address or one enclosed in brackets. The address needs to be
+enclosed in brackets if you want to pass in a new port value as well.
+
+=item $uri->ihost
+
+Returns the host in Unicode form. Any IDNA A-labels are turned into U-labels.
+
+=item $uri->port
+
+=item $uri->port( $new_port )
+
+Sets and returns the port. The port is a simple integer
+that should be greater than 0.
+
+If a port is not specified explicitly in the URI, then the URI scheme's default port
+is returned. If you don't want the default port
+substituted, then you can use the $uri->_port method instead.
+
+=item $uri->host_port
+
+=item $uri->host_port( $new_host_port )
+
+Sets and returns the host and port as a single
+unit. The returned value includes a port, even if it matches the
+default port. The host part and the port part are separated by a
+colon: ":".
+
+For IPv6 addresses the bracketing is preserved; thus
+URI->new("http://[::1]/")->host_port returns "[::1]:80". Contrast this with
+$uri->host which will remove the brackets.
+
+=item $uri->default_port
+

+
+Scheme-specific support is provided for the following URI schemes. For C<URI>
+objects that do not belong to one of these, you can only use the common and
+generic methods.
+
+=over 4
+
+=item B<data>:
+
+The I<data> URI scheme is specified in RFC 2397. It allows inclusion
+of small data items as "immediate" data, as if it had been included
+externally.
+
+C<URI> objects belonging to the data scheme support the common methods
+and two new methods to access their scheme-specific components:
+$uri->media_type and $uri->data. See L<URI::data> for details.
+
+=item B<file>:
+
+An old specification of the I<file> URI scheme is found in RFC 1738.
+A new RFC 2396 based specification in not available yet, but file URI
+references are in common use.
+
+C<URI> objects belonging to the file scheme support the common and
+generic methods. In addition, they provide two methods for mapping file URIs
+back to local file names; $uri->file and $uri->dir. See L<URI::file>
+for details.
+
+=item B<ftp>:
+
+An old specification of the I<ftp> URI scheme is found in RFC 1738. A
+new RFC 2396 based specification in not available yet, but ftp URI
+references are in common use.
+
+C<URI> objects belonging to the ftp scheme support the common,
+generic and server methods. In addition, they provide two methods for
+accessing the userinfo sub-components: $uri->user and $uri->password.
+
+=item B<gopher>:
+
+The I<gopher> URI scheme is specified in
+<draft-murali-url-gopher-1996-12-04> and will hopefully be available
+as a RFC 2396 based specification.
+
+C<URI> objects belonging to the gopher scheme support the common,
+generic and server methods. In addition, they support some methods for
+accessing gopher-specific path components: $uri->gopher_type,
+$uri->selector, $uri->search, $uri->string.
+
+=item B<http>:
+
+The I<http> URI scheme is specified in RFC 2616.
+The scheme is used to reference resources hosted by HTTP servers.
+
+C<URI> objects belonging to the http scheme support the common,
+generic and server methods.
+
+=item B<https>:
+
+The I<https> URI scheme is a Netscape invention which is commonly
+implemented. The scheme is used to reference HTTP servers through SSL
+connections. Its syntax is the same as http, but the default
+port is different.
+
+=item B<ldap>:
+
+The I<ldap> URI scheme is specified in RFC 2255. LDAP is the
+Lightweight Directory Access Protocol. An ldap URI describes an LDAP
+search operation to perform to retrieve information from an LDAP
+directory.
+
+C<URI> objects belonging to the ldap scheme support the common,
+generic and server methods as well as ldap-specific methods: $uri->dn,
+$uri->attributes, $uri->scope, $uri->filter, $uri->extensions. See
+L<URI::ldap> for details.
+
+=item B<ldapi>:
+
+Like the I<ldap> URI scheme, but uses a UNIX domain socket. The
+server methods are not supported, and the local socket path is
+available as $uri->un_path. The I<ldapi> scheme is used by the
+OpenLDAP package. There is no real specification for it, but it is
+mentioned in various OpenLDAP manual pages.
+
+=item B<ldaps>:
+
+Like the I<ldap> URI scheme, but uses an SSL connection. This
+scheme is deprecated, as the preferred way is to use the I<start_tls>
+mechanism.
+
+=item B<mailto>:
+
+The I<mailto> URI scheme is specified in RFC 2368. The scheme was
+originally used to designate the Internet mailing address of an
+individual or service. It has (in RFC 2368) been extended to allow
+setting of other mail header fields and the message body.
+
+C<URI> objects belonging to the mailto scheme support the common
+methods and the generic query methods. In addition, they support the
+following mailto-specific methods: $uri->to, $uri->headers.
+
+Note that the "foo@example.com" part of a mailto is I<not> the
+C<userinfo> and C<host> but instead the C<path>. This allows a
+mailto URI to contain multiple comma separated email addresses.
+
+=item B<mms>:
+
+The I<mms> URL specification can be found at L<http://sdp.ppona.com/>.
+C<URI> objects belonging to the mms scheme support the common,
+generic, and server methods, with the exception of userinfo and
+query-related sub-components.
+
+=item B<news>:
+
+The I<news>, I<nntp> and I<snews> URI schemes are specified in
+<draft-gilman-news-url-01> and will hopefully be available as an RFC
+2396 based specification soon.
+
+C<URI> objects belonging to the news scheme support the common,
+generic and server methods. In addition, they provide some methods to
+access the path: $uri->group and $uri->message.
+
+=item B<nntp>:
+
+See I<news> scheme.
+
+=item B<pop>:
+
+The I<pop> URI scheme is specified in RFC 2384. The scheme is used to
+reference a POP3 mailbox.
+
+C<URI> objects belonging to the pop scheme support the common, generic
+and server methods. In addition, they provide two methods to access the
+userinfo components: $uri->user and $uri->auth
+
+=item B<rlogin>:
+
+An old specification of the I<rlogin> URI scheme is found in RFC
+1738. C<URI> objects belonging to the rlogin scheme support the
+common, generic and server methods.
+
+=item B<rtsp>:
+
+The I<rtsp> URL specification can be found in section 3.2 of RFC 2326.
+C<URI> objects belonging to the rtsp scheme support the common,
+generic, and server methods, with the exception of userinfo and
+query-related sub-components.
+
+=item B<rtspu>:
+
+The I<rtspu> URI scheme is used to talk to RTSP servers over UDP
+instead of TCP. The syntax is the same as rtsp.
+
+=item B<rsync>:
+
+Information about rsync is available from L<http://rsync.samba.org/>.
+C<URI> objects belonging to the rsync scheme support the common,
+generic and server methods. In addition, they provide methods to
+access the userinfo sub-components: $uri->user and $uri->password.
+
+=item B<sip>:
+
+The I<sip> URI specification is described in sections 19.1 and 25
+of RFC 3261. C<URI> objects belonging to the sip scheme support the
+common, generic, and server methods with the exception of path related
+sub-components. In addition, they provide two methods to get and set
+I<sip> parameters: $uri->params_form and $uri->params.
+
+=item B<sips>:
+
+See I<sip> scheme. Its syntax is the same as sip, but the default
+port is different.
+
+=item B<snews>:
+
+See I<news> scheme. Its syntax is the same as news, but the default
+port is different.
+
+=item B<telnet>:
+
+An old specification of the I<telnet> URI scheme is found in RFC
+1738. C<URI> objects belonging to the telnet scheme support the
+common, generic and server methods.
+
+=item B<tn3270>:
+
+These URIs are used like I<telnet> URIs but for connections to IBM
+mainframes. C<URI> objects belonging to the tn3270 scheme support the
+common, generic and server methods.
+
+=item B<ssh>:
+
+Information about ssh is available at L<http://www.openssh.com/>.
+C<URI> objects belonging to the ssh scheme support the common,
+generic and server methods. In addition, they provide methods to
+access the userinfo sub-components: $uri->user and $uri->password.
+
+=item B<urn>:
+
+The syntax of Uniform Resource Names is specified in RFC 2141. C<URI>
+objects belonging to the urn scheme provide the common methods, and also the
+methods $uri->nid and $uri->nss, which return the Namespace Identifier
+and the Namespace-Specific String respectively.
+
+The Namespace Identifier basically works like the Scheme identifier of
+URIs, and further divides the URN namespace. Namespace Identifier
+assignments are maintained at
+L<http://www.iana.org/assignments/urn-namespaces>.
+
+Letter case is not significant for the Namespace Identifier. It is
+always returned in lower case by the $uri->nid method. The $uri->_nid
+method can be used if you want it in its original case.
+
+=item B<urn>:B<isbn>:
+
+The C<urn:isbn:> namespace contains International Standard Book
+Numbers (ISBNs) and is described in RFC 3187. A C<URI> object belonging
+to this namespace has the following extra methods (if the
+Business::ISBN module is available): $uri->isbn,
+$uri->isbn_publisher_code, $uri->isbn_group_code (formerly isbn_country_code,
+which is still supported by issues a deprecation warning), $uri->isbn_as_ean.
+
+=item B<urn>:B<oid>:
+
+The C<urn:oid:> namespace contains Object Identifiers (OIDs) and is
+described in RFC 3061. An object identifier consists of sequences of digits
+separated by dots. A C<URI> object belonging to this namespace has an
+additional method called $uri->oid that can be used to get/set the oid
+value. In a list context, oid numbers are returned as separate elements.

+=back
+
+=head1 CONFIGURATION VARIABLES
+
+The following configuration variables influence how the class and its
+methods behave:
+
+=over 4
+
+=item $URI::ABS_ALLOW_RELATIVE_SCHEME
+
+Some older parsers used to allow the scheme name to be present in the
+relative URL if it was the same as the base URL scheme. RFC 2396 says
+that this should be avoided, but you can enable this old behaviour by
+setting the $URI::ABS_ALLOW_RELATIVE_SCHEME variable to a TRUE value.
+The difference is demonstrated by the following examples:
+
+ URI->new("http:foo")->abs("http://host/a/b")
+ ==> "http:foo"
+
+ local $URI::ABS_ALLOW_RELATIVE_SCHEME = 1;
+ URI->new("http:foo")->abs("http://host/a/b")
+ ==> "http:/host/a/foo"
+
+
+=item $URI::ABS_REMOTE_LEADING_DOTS
+
+You can also have the abs() method ignore excess ".."
+segments in the relative URI by setting $URI::ABS_REMOTE_LEADING_DOTS
+to a TRUE value. The difference is demonstrated by the following
+examples:
+
+ URI->new("../../../foo")->abs("http://host/a/b")
+ ==> "http://host/../../foo"
+
+ local $URI::ABS_REMOTE_LEADING_DOTS = 1;
+ URI->new("../../../foo")->abs("http://host/a/b")
+ ==> "http://host/foo"
+
+=item $URI::DEFAULT_QUERY_FORM_DELIMITER
+
+This value can be set to ";" to have the query form C<key=value> pairs
+delimited by ";" instead of "&" which is the default.
+
+=back
+
+=head1 BUGS
+
+Using regexp variables like $1 directly as arguments to the URI methods
+does not work too well with current perl implementations. I would argue
+that this is actually a bug in perl. The workaround is to quote
+them. Example:
+
+ /(...)/ || die;
+ $u->query("$1");
+
+=head1 PARSING URIs WITH REGEXP
+
+As an alternative to this module, the following (official) regular
+expression can be used to decode a URI:
+
+ my($scheme, $authority, $path, $query, $fragment) =
+ $uri =~ m|(?:([^:/?#]+):)?(?://([^/?#]*))?([^?#]*)(?:\?([^#]*))?(?:#(.*))?|;
+
+The C<URI::Split> module provides the function uri_split() as a
+readable alternative.

+package URI::Escape;

+
+=head1 NAME
+
+URI::Escape - Percent-encode and percent-decode unsafe characters
+
+=head1 SYNOPSIS
+
+ use URI::Escape;
+ $safe = uri_escape("10% is enough\n");
+ $verysafe = uri_escape("foo", "\0-\377");
+ $str = uri_unescape($safe);
+
+=head1 DESCRIPTION
+
+This module provides functions to percent-encode and percent-decode URI strings as
+defined by RFC 3986. Percent-encoding URI's is informally called "URI escaping".
+This is the terminology used by this module, which predates the formalization of the
+terms by the RFC by several years.
+
+A URI consists of a restricted set of characters. The restricted set
+of characters consists of digits, letters, and a few graphic symbols
+chosen from those common to most of the character encodings and input
+facilities available to Internet users. They are made up of the
+"unreserved" and "reserved" character sets as defined in RFC 3986.
+
+ unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
+ reserved = ":" / "/" / "?" / "#" / "[" / "]" / "@"
+ "!" / "$" / "&" / "'" / "(" / ")"
+ / "*" / "+" / "," / ";" / "="
+
+In addition, any byte (octet) can be represented in a URI by an escape
+sequence: a triplet consisting of the character "%" followed by two
+hexadecimal digits. A byte can also be represented directly by a
+character, using the US-ASCII character for that octet.
+
+Some of the characters are I<reserved> for use as delimiters or as
+part of certain URI components. These must be escaped if they are to
+be treated as ordinary data. Read RFC 3986 for further details.
+
+The functions provided (and exported by default) from this module are:
+
+=over 4
+
+=item uri_escape( $string )
+
+=item uri_escape( $string, $unsafe )
+
+Replaces each unsafe character in the $string with the corresponding
+escape sequence and returns the result. The $string argument should
+be a string of bytes. The uri_escape() function will croak if given a
+characters with code above 255. Use uri_escape_utf8() if you know you
+have such chars or/and want chars in the 128 .. 255 range treated as
+UTF-8.
+
+The uri_escape() function takes an optional second argument that
+overrides the set of characters that are to be escaped. The set is
+specified as a string that can be used in a regular expression
+character class (between [ ]). E.g.:
+
+ "\x00-\x1f\x7f-\xff" # all control and hi-bit characters
+ "a-z" # all lower case characters
+ "^A-Za-z" # everything not a letter
+
+The default set of characters to be escaped is all those which are
+I<not> part of the C<unreserved> character class shown above as well
+as the reserved characters. I.e. the default is:
+
+ "^A-Za-z0-9\-\._~"
+
+=item uri_escape_utf8( $string )
+
+=item uri_escape_utf8( $string, $unsafe )
+
+Works like uri_escape(), but will encode chars as UTF-8 before
+escaping them. This makes this function able to deal with characters
+with code above 255 in $string. Note that chars in the 128 .. 255
+range will be escaped differently by this function compared to what
+uri_escape() would. For chars in the 0 .. 127 range there is no
+difference.
+
+Equivalent to:
+
+ utf8::encode($string);
+ my $uri = uri_escape($string);
+
+Note: JavaScript has a function called escape() that produces the
+sequence "%uXXXX" for chars in the 256 .. 65535 range. This function
+has really nothing to do with URI escaping but some folks got confused
+since it "does the right thing" in the 0 .. 255 range. Because of
+this you sometimes see "URIs" with these kind of escapes. The
+JavaScript encodeURIComponent() function is similar to uri_escape_utf8().
+
+=item uri_unescape($string,...)
+
+Returns a string with each %XX sequence replaced with the actual byte
+(octet).
+
+This does the same as:
+
+ $string =~ s/%([0-9A-Fa-f]{2})/chr(hex($1))/eg;
+
+but does not modify the string in-place as this RE would. Using the
+uri_unescape() function instead of the RE might make the code look
+cleaner and is a few characters less to type.
+
+In a simple benchmark test I did,
+calling the function (instead of the inline RE above) if a few chars
+were unescaped was something like 40% slower, and something like 700% slower if none were. If
+you are going to unescape a lot of times it might be a good idea to
+inline the RE.
+
+If the uri_unescape() function is passed multiple strings, then each
+one is returned unescaped.
+
+=back
+
+The module can also export the C<%escapes> hash, which contains the
+mapping from all 256 bytes to the corresponding escape codes. Lookup
+in this hash is faster than evaluating C<sprintf("%%%02X", ord($byte))>
+each time.

+URI::Heuristic - Expand URI using heuristics

+
+=head1 DESCRIPTION
+
+This module provides functions that expand strings into real absolute
+URIs using some built-in heuristics. Strings that already represent
+absolute URIs (i.e. that start with a C<scheme:> part) are never modified
+and are returned unchanged. The main use of these functions is to
+allow abbreviated URIs similar to what many web browsers allow for URIs
+typed in by the user.
+
+The following functions are provided:
+
+=over 4
+
+=item uf_uristr($str)
+
+Tries to make the argument string
+into a proper absolute URI string. The "uf_" prefix stands for "User
+Friendly". Under MacOS, it assumes that any string with a common URL
+scheme (http, ftp, etc.) is a URL rather than a local path. So don't name
+your volumes after common URL schemes and expect uf_uristr() to construct
+valid file: URL's on those volumes for you, because it won't.
+
+=item uf_uri($str)
+
+Works the same way as uf_uristr() but
+returns a C<URI> object.
+
+=back
+
+=head1 ENVIRONMENT
+
+If the hostname portion of a URI does not contain any dots, then
+certain qualified guesses are made. These guesses are governed by
+the following environment variables:
+
+=over 10
+
+=item COUNTRY
+
+The two-letter country code (ISO 3166) for your location. If
+the domain name of your host ends with two letters, then it is taken
+to be the default country. See also L<Locale::Country>.
+
+=item HTTP_ACCEPT_LANGUAGE, LC_ALL, LANG
+
+If COUNTRY is not set, these standard environment variables are
+examined and country (not language) information possibly found in them
+is used as the default country.
+
+=item URL_GUESS_PATTERN
+
+Contains a space-separated list of URL patterns to try. The string
+"ACME" is for some reason used as a placeholder for the host name in
+the URL provided. Example:
+
+ URL_GUESS_PATTERN="www.ACME.no www.ACME.se www.ACME.com"
+ export URL_GUESS_PATTERN
+
+Specifying URL_GUESS_PATTERN disables any guessing rules based on
+country. An empty URL_GUESS_PATTERN disables any guessing that
+involves host name lookups.

+
+URI::QueryParam - Additional query methods for URIs
+
+=head1 SYNOPSIS
+
+ use URI;
+ use URI::QueryParam;
+
+ $u = URI->new("", "http");
+ $u->query_param(foo => 1, 2, 3);
+ print $u->query; # prints foo=1&foo=2&foo=3
+
+ for my $key ($u->query_param) {
+ print "$key: ", join(", ", $u->query_param($key)), "\n";
+ }
+
+=head1 DESCRIPTION
+
+Loading the C<URI::QueryParam> module adds some extra methods to
+URIs that support query methods. These methods provide an alternative
+interface to the $u->query_form data.
+
+The query_param_* methods have deliberately been made identical to the
+interface of the corresponding C<CGI.pm> methods.
+
+The following additional methods are made available:
+
+=over
+
+=item @keys = $u->query_param
+
+=item @values = $u->query_param( $key )
+
+=item $first_value = $u->query_param( $key )
+
+=item $u->query_param( $key, $value,... )
+
+If $u->query_param is called with no arguments, it returns all the
+distinct parameter keys of the URI. In a scalar context it returns the
+number of distinct keys.
+
+When a $key argument is given, the method returns the parameter values with the
+given key. In a scalar context, only the first parameter value is
+returned.
+
+If additional arguments are given, they are used to update successive
+parameters with the given key. If any of the values provided are
+array references, then the array is dereferenced to get the actual
+values.
+
+=item $u->query_param_append($key, $value,...)
+
+Adds new parameters with the given
+key without touching any old parameters with the same key. It
+can be explained as a more efficient version of:
+
+ $u->query_param($key,
+ $u->query_param($key),
+ $value,...);
+
+One difference is that this expression would return the old values
+of $key, whereas the query_param_append() method does not.
+
+=item @values = $u->query_param_delete($key)
+
+=item $first_value = $u->query_param_delete($key)
+
+Deletes all key/value pairs with the given key.
+The old values are returned. In a scalar context, only the first value
+is returned.
+
+Using the query_param_delete() method is slightly more efficient than
+the equivalent:
+
+ $u->query_param($key, []);
+
+=item $hashref = $u->query_form_hash
+
+=item $u->query_form_hash( \%new_form )
+
+Returns a reference to a hash that represents the
+query form's key/value pairs. If a key occurs multiple times, then the hash
+value becomes an array reference.
+
+Note that sequence information is lost. This means that:
+
+ $u->query_form_hash($u->query_form_hash);
+
+is not necessarily a no-op, as it may reorder the key/value pairs.
+The values returned by the query_param() method should stay the same
+though.

+URI::Split - Parse and compose URI strings
+
+=head1 SYNOPSIS

+ ($scheme, $auth, $path, $query, $frag) = uri_split($uri);
+ $uri = uri_join($scheme, $auth, $path, $query, $frag);
+
+=head1 DESCRIPTION
+
+Provides functions to parse and compose URI
+strings. The following functions are provided:
+
+=over
+
+=item ($scheme, $auth, $path, $query, $frag) = uri_split($uri)
+
+Breaks up a URI string into its component
+parts. An C<undef> value is returned for those parts that are not
+present. The $path part is always present (but can be the empty
+string) and is thus never returned as C<undef>.
+
+No sensible value is returned if this function is called in a scalar
+context.
+
+=item $uri = uri_join($scheme, $auth, $path, $query, $frag)
+
+Puts together a URI string from its parts.
+Missing parts are signaled by passing C<undef> for the corresponding
+argument.
+
+Minimal escaping is applied to parts that contain reserved chars
+that would confuse a parser. For instance, any occurrence of '?' or '#'
+in $path is always escaped, as it would otherwise be parsed back
+as a query or fragment.

+=head1 DESCRIPTION
+
+This module is provided for backwards compatibility with modules that
+depend on the interface provided by the C<URI::URL> class that used to
+be distributed with the libwww-perl library.
+
+The following differences exist compared to the C<URI> class interface:
+
+=over 3
+
+=item *
+
+The URI::URL module exports the url() function as an alternate
+constructor interface.
+
+=item *
+
+The constructor takes an optional $base argument. The C<URI::URL>
+class is a subclass of C<URI::WithBase>.
+
+=item *
+
+The URI::URL->newlocal class method is the same as URI::file->new_abs.

+
+=item *
+
+$url->print_on method
+
+=item *
+
+$url->crack method
+
+=item *
+
+$url->full_path: same as ($uri->abs_path || "/")
+
+=item *
+
+$url->netloc: same as $uri->authority
+
+=item *
+
+$url->epath, $url->equery: same as $uri->path, $uri->query
+
+=item *
+
+$url->path and $url->query pass unescaped strings.
+
+=item *
+
+$url->path_components: same as $uri->path_segments (if you don't
+consider path segment parameters)
+
+=item *
+
+$url->params and $url->eparams methods
+
+=item *
+
+$url->base method. See L<URI::WithBase>.
+
+=item *
+
+$url->abs and $url->rel have an optional $base argument. See
+L<URI::WithBase>.
+
+=item *
+
+$url->frag: same as $uri->fragment
+
+=item *
+
+$url->keywords: same as $uri->query_keywords
+
+=item *
+
+$url->localpath and friends map to $uri->file.
+

+=head1 NAME
+
+URI::WithBase - URIs which remember their base
+
+=head1 SYNOPSIS
+
+ $u1 = URI::WithBase->new($str, $base);
+ $u2 = $u1->abs;
+
+ $base = $u1->base;
+ $u1->base( $new_base )
+
+=head1 DESCRIPTION
+
+This module provides the C<URI::WithBase> class. Objects of this class
+are like C<URI> objects, but can keep their base too. The base
+represents the context where this URI was found and can be used to
+absolutize or relativize the URI. All the methods described in L<URI>
+are supported for C<URI::WithBase> objects.
+
+The methods provided in addition to or modified from those of C<URI> are:
+
+=over 4
+
+=item $uri = URI::WithBase->new($str, [$base])
+
+The constructor takes an optional base URI as the second argument.
+If provided, this argument initializes the base attribute.
+
+=item $uri->base( [$new_base] )
+
+Can be used to get or set the value of the base attribute.
+The return value, which is the old value, is a URI object or C<undef>.
+
+=item $uri->abs( [$base_uri] )
+
+The $base_uri argument is now made optional as the object carries its
+base with it. A new object is returned even if $uri is already
+absolute (while plain URI objects simply return themselves in
+that case).
+
+=item $uri->rel( [$base_uri] )
+
+The $base_uri argument is now made optional as the object carries its
+base with it. A new object is always returned.

+ use URI::_punycode;
+ $punycode = encode_punycode($unicode);
+ $unicode = decode_punycode($punycode);
+
+=head1 DESCRIPTION
+
+URI::_punycode is a module to encode / decode Unicode strings into
+Punycode, an efficient encoding of Unicode for use with IDNA.
+
+This module requires Perl 5.6.0 or over to handle UTF8 flagged Unicode
+strings.
+
+=head1 FUNCTIONS
+
+This module exports following functions by default.
+
+=over 4
+
+=item encode_punycode
+
+ $punycode = encode_punycode($unicode);
+
+takes Unicode string (UTF8-flagged variable) and returns Punycode
+encoding for it.
+
+=item decode_punycode
+
+ $unicode = decode_punycode($punycode)
+
+takes Punycode encoding and returns original Unicode string.
+
+=back
+
+These functions throw exceptions on failure. You can catch 'em via
+C<eval>.

+=head1 DESCRIPTION
+
+The C<URI::data> class supports C<URI> objects belonging to the I<data>
+URI scheme. The I<data> URI scheme is specified in RFC 2397. It
+allows inclusion of small data items as "immediate" data, as if it had
+been included externally. Examples:
+
+ data:,Perl%20is%20good
+
+ data:image/gif;base64,R0lGODdhIAAgAIAAAAAAAPj8+CwAAAAAI

+ JtnE2KizVUkYJVZZ1nczBxXlFopZBtoJ2diXGdNUymmJdFMAADs=
+
+
+
+C<URI> objects belonging to the data scheme support the common methods
+(described in L<URI>) and the following two scheme-specific methods:
+
+=over 4
+
+=item $uri->media_type( [$new_media_type] )
+
+Can be used to get or set the media type specified in the
+URI. If no media type is specified, then the default
+C<"text/plain;charset=US-ASCII"> is returned.
+
+=item $uri->data( [$new_data] )
+
+Can be used to get or set the data contained in the URI.
+The data is passed unescaped (in binary form). The decision about
+whether to base64 encode the data in the URI is taken automatically,
+based on the encoding that produces the shorter URI string.

+
+URI::file - URI that maps to local file names
+
+=head1 SYNOPSIS
+
+ use URI::file;
+
+ $u1 = URI->new("file:/foo/bar");
+ $u2 = URI->new("foo/bar", "file");
+
+ $u3 = URI::file->new($path);
+ $u4 = URI::file->new("c:\\windows\\", "win32");
+
+ $u1->file;
+ $u1->file("mac");
+
+=head1 DESCRIPTION
+
+The C<URI::file> class supports C<URI> objects belonging to the I<file>
+URI scheme. This scheme allows us to map the conventional file names
+found on various computer systems to the URI name space. An old
+specification of the I<file> URI scheme is found in RFC 1738. Some
+older background information is also in RFC 1630. There are no newer
+specifications as far as I know.
+
+If you simply want to construct I<file> URI objects from URI strings,
+use the normal C<URI> constructor. If you want to construct I<file>
+URI objects from the actual file names used by various systems, then
+use one of the following C<URI::file> constructors:
+
+=over 4
+
+=item $u = URI::file->new( $filename, [$os] )
+
+Maps a file name to the I<file:> URI name space, creates a URI object
+and returns it. The $filename is interpreted as belonging to the
+indicated operating system ($os), which defaults to the value of the
+$^O variable. The $filename can be either absolute or relative, and
+the corresponding type of URI object for $os is returned.
+
+=item $u = URI::file->new_abs( $filename, [$os] )
+
+Same as URI::file->new, but makes sure that the URI returned
+represents an absolute file name. If the $filename argument is
+relative, then the name is resolved relative to the current directory,
+i.e. this constructor is really the same as:
+
+ URI::file->new($filename)->abs(URI::file->cwd);
+
+=item $u = URI::file->cwd
+
+Returns a I<file> URI that represents the current working directory.
+See L<Cwd>.
+
+=back
+
+The following methods are supported for I<file> URI (in addition to
+the common and generic methods described in L<URI>):
+
+=over 4
+
+=item $u->file( [$os] )
+
+Returns a file name. It maps from the URI name space
+to the file name space of the indicated operating system.
+
+It might return C<undef> if the name can not be represented in the
+indicated file system.
+
+=item $u->dir( [$os] )
+
+Some systems use a different form for names of directories than for plain
+files. Use this method if you know you want to use the name for
+a directory.
+
+=back
+
+The C<URI::file> module can be used to map generic file names to names
+suitable for the current system. As such, it can work as a nice
+replacement for the C<File::Spec> module. For instance, the following
+code translates the UNIX-style file name F<Foo/Bar.pm> to a name
+suitable for the local system:
+
+ $file = URI::file->new("Foo/Bar.pm", "unix")->file;
+ die "Can't map filename Foo/Bar.pm for $^O" unless defined $file;
+ open(FILE, $file) || die "Can't open '$file': $!";
+ # do something with FILE
+
+=head1 MAPPING NOTES
+
+Most computer systems today have hierarchically organized file systems.
+Mapping the names used in these systems to the generic URI syntax
+allows us to work with relative file URIs that behave as they should
+when resolved using the generic algorithm for URIs (specified in RFC
+2396). Mapping a file name to the generic URI syntax involves mapping
+the path separator character to "/" and encoding any reserved
+characters that appear in the path segments of the file name. If
+path segments consisting of the strings "." or ".." have a
+different meaning than what is specified for generic URIs, then these
+must be encoded as well.
+
+If the file system has device, volume or drive specifications as
+the root of the name space, then it makes sense to map them to the
+authority field of the generic URI syntax. This makes sure that
+relative URIs can not be resolved "above" them, i.e. generally how
+relative file names work in those systems.
+
+Another common use of the authority field is to encode the host on which
+this file name is valid. The host name "localhost" is special and
+generally has the same meaning as a missing or empty authority
+field. This use is in conflict with using it as a device
+specification, but can often be resolved for device specifications
+having characters not legal in plain host names.
+
+File name to URI mapping in normally not one-to-one. There are
+usually many URIs that map to any given file name. For instance, an
+authority of "localhost" maps the same as a URI with a missing or empty
+authority.
+
+Example 1: The Mac uses ":" as path separator, but not in the same way
+as a generic URI. ":foo" is a relative name. "foo:bar" is an absolute
+name. Also, path segments can contain the "/" character as well as the
+literal "." or "..". So the mapping looks like this:
+
+ Mac URI
+ ---------- -------------------
+ :foo:bar <==> foo/bar
+ : <==> ./
+ ::foo:bar <==> ../foo/bar
+ ::: <==> ../../
+ foo:bar <==> file:/foo/bar
+ foo:bar: <==> file:/foo/bar/
+ .. <==> %2E%2E
+ <undef> <== /
+ foo/ <== file:/foo%2F
+ ./foo.txt <== file:/.%2Ffoo.txt
+
+Note that if you want a relative URL, you *must* begin the path with a :. Any
+path that begins with [^:] is treated as absolute.
+
+Example 2: The UNIX file system is easy to map, as it uses the same path
+separator as URIs, has a single root, and segments of "." and ".."
+have the same meaning. URIs that have the character "\0" or "/" as
+part of any path segment can not be turned into valid UNIX file names.
+
+ UNIX URI
+ ---------- ------------------
+ foo/bar <==> foo/bar
+ /foo/bar <==> file:/foo/bar
+ /foo/bar <== file://localhost/foo/bar
+ file: ==> ./file:
+ <undef> <== file:/fo%00/bar
+ / <==> file:/

+RFC 1630
+
+ [...]
+
+ There is clearly a danger of confusion that a link made to a local
+ file should be followed by someone on a different system, with
+ unexpected and possibly harmful results. Therefore, the convention
+ is that even a "file" URL is provided with a host part. This allows
+ a client on another system to know that it cannot access the file
+ system, or perhaps to use some other local mechanism to access the
+ file.
+
+ The special value "localhost" is used in the host field to indicate
+ that the filename should really be used on whatever host one is.
+ This for example allows links to be made to files which are
+ distributed on many machines, or to "your unix local password file"
+ subject of course to consistency across the users of the data.
+
+ A void host field is equivalent to "localhost".
+
+=head1 CONFIGURATION VARIABLES
+
+The following configuration variables influence how the class and its
+methods behave:
+
+=over
+
+=item %URI::file::OS_CLASS
+
+This hash maps OS identifiers to implementation classes. You might
+want to add or modify this if you want to plug in your own file
+handler class. Normally the keys should match the $^O values in use.
+
+If there is no mapping then the "Unix" implementation is used.
+
+=item $URI::file::DEFAULT_AUTHORITY
+
+This determine what "authority" string to include in absolute file
+URIs. It defaults to "". If you prefer verbose URIs you might set it
+to be "localhost".
+
+Setting this value to C<undef> force behaviour compatible to URI v1.31
+and earlier. In this mode host names in UNC paths and drive letters
+are mapped to the authority component on Windows, while we produce
+authority-less URIs on Unix.

+=head1 NAME
+
+URI::ldap - LDAP Uniform Resource Locators
+
+=head1 SYNOPSIS
+
+ use URI;
+
+ $uri = URI->new("ldap:$uri_string");
+ $dn = $uri->dn;
+ $filter = $uri->filter;
+ @attr = $uri->attributes;
+ $scope = $uri->scope;
+ %extn = $uri->extensions;
+
+ $uri = URI->new("ldap:"); # start empty
+ $uri->host("ldap.itd.umich.edu");
+ $uri->dn("o=University of Michigan,c=US");
+ $uri->attributes(qw(postalAddress));
+ $uri->scope('sub');
+ $uri->filter('(cn=Babs Jensen)');
+ print $uri->as_string,"\n";
+
+=head1 DESCRIPTION
+
+C<URI::ldap> provides an interface to parse an LDAP URI into its
+constituent parts and also to build a URI as described in
+RFC 2255.
+
+=head1 METHODS
+
+C<URI::ldap> supports all the generic and server methods defined by
+L<URI>, plus the following.
+
+Each of the following methods can be used to set or get the value in
+the URI. The values are passed in unescaped form. None of these
+return undefined values, but elements without a default can be empty.
+If arguments are given, then a new value is set for the given part
+of the URI.
+
+=over 4
+
+=item $uri->dn( [$new_dn] )
+
+Sets or gets the I<Distinguished Name> part of the URI. The DN
+identifies the base object of the LDAP search.
+
+=item $uri->attributes( [@new_attrs] )
+
+Sets or gets the list of attribute names which are
+returned by the search.
+
+=item $uri->scope( [$new_scope] )
+
+Sets or gets the scope to be used by the search. The value can be one of
+C<"base">, C<"one"> or C<"sub">. If none is given in the URI then the
+return value defaults to C<"base">.
+
+=item $uri->_scope( [$new_scope] )
+
+Same as scope(), but does not default to anything.
+
+=item $uri->filter( [$new_filter] )
+
+Sets or gets the filter to be used by the search. If none is given in
+the URI then the return value defaults to C<"(objectClass=*)">.
+
+=item $uri->_filter( [$new_filter] )
+
+Same as filter(), but does not default to anything.
+
+=item $uri->extensions( [$etype => $evalue,...] )
+
+Sets or gets the extensions used for the search. The list passed should
+be in the form etype1 => evalue1, etype2 => evalue2,... This is also
+the form of list that is returned.

+=head1 NAME
+
+WWW::RobotRules - database of robots.txt-derived permissions
+
+=head1 SYNOPSIS
+
+ use WWW::RobotRules;
+ my $rules = WWW::RobotRules->new('MOMspider/1.0');
+
+ use LWP::Simple qw(get);
+
+ {
+ my $url = "http://some.place/robots.txt";
+ my $robots_txt = get $url;
+ $rules->parse($url, $robots_txt) if defined $robots_txt;
+ }
+
+ {
+ my $url = "http://some.other.place/robots.txt";
+ my $robots_txt = get $url;
+ $rules->parse($url, $robots_txt) if defined $robots_txt;
+ }
+
+ # Now we can check if a URL is valid for those servers
+ # whose "robots.txt" files we've gotten and parsed:
+ if($rules->allowed($url)) {
+ $c = get $url;
+ ...
+ }
+
+=head1 DESCRIPTION
+
+This module parses F</robots.txt> files as specified in
+"A Standard for Robot Exclusion", at
+<http://www.robotstxt.org/wc/norobots.html>
+Webmasters can use the F</robots.txt> file to forbid conforming
+robots from accessing parts of their web site.
+
+The parsed files are kept in a WWW::RobotRules object, and this object
+provides methods to check if access to a given URL is prohibited. The
+same WWW::RobotRules object can be used for one or more parsed
+F</robots.txt> files on any number of hosts.
+
+The following methods are provided:
+
+=over 4
+
+=item $rules = WWW::RobotRules->new($robot_name)
+
+This is the constructor for WWW::RobotRules objects. The first
+argument given to new() is the name of the robot.
+
+=item $rules->parse($robot_txt_url, $content, $fresh_until)
+
+The parse() method takes as arguments the URL that was used to
+retrieve the F</robots.txt> file, and the contents of the file.
+
+=item $rules->allowed($uri)
+
+Returns TRUE if this robot is allowed to retrieve this URL.
+
+=item $rules->agent([$name])
+
+Get/set the agent name. NOTE: Changing the agent name will clear the robots.txt
+rules and expire times out of the cache.
+
+=back
+
+=head1 ROBOTS.TXT
+
+The format and semantics of the "/robots.txt" file are as follows
+(this is an edited abstract of
+<http://www.robotstxt.org/wc/norobots.html>):
+
+The file consists of one or more records separated by one or more
+blank lines. Each record contains lines of the form
+
+ <field-name>: <value>
+
+The field name is case insensitive. Text after the '#' character on a
+line is ignored during parsing. This is used for comments. The
+following <field-names> can be used:
+
+=over 3
+
+=item User-Agent
+
+The value of this field is the name of the robot the record is
+describing access policy for. If more than one I<User-Agent> field is
+present the record describes an identical access policy for more than
+one robot. At least one field needs to be present per record. If the
+value is '*', the record describes the default access policy for any
+robot that has not not matched any of the other records.
+
+The I<User-Agent> fields must occur before the I<Disallow> fields. If a
+record contains a I<User-Agent> field after a I<Disallow> field, that
+constitutes a malformed record. This parser will assume that a blank
+line should have been placed before that I<User-Agent> field, and will
+break the record into two. All the fields before the I<User-Agent> field
+will constitute a record, and the I<User-Agent> field will be the first
+field in a new record.
+
+=item Disallow
+
+The value of this field specifies a partial URL that is not to be
+visited. This can be a full path, or a partial path; any URL that
+starts with this value will not be retrieved
+
+=back
+
+Unrecognized records are ignored.
+
+=head1 ROBOTS.TXT EXAMPLES
+
+The following example "/robots.txt" file specifies that no robots
+should visit any URL starting with "/cyberworld/map/" or "/tmp/":
+
+ User-agent: *
+ Disallow: /cyberworld/map/ # This is an infinite virtual URL space
+ Disallow: /tmp/ # these will soon disappear
+
+This example "/robots.txt" file specifies that no robots should visit
+any URL starting with "/cyberworld/map/", except the robot called
+"cybermapper":
+
+ User-agent: *
+ Disallow: /cyberworld/map/ # This is an infinite virtual URL space
+
+ # Cybermapper knows where to go.
+ User-agent: cybermapper
+ Disallow:
+
+This example indicates that no robots should visit this site further:
+
+ # go away
+ User-agent: *
+ Disallow: /
+
+This is an example of a malformed robots.txt file.
+
+ # robots.txt for ancientcastle.example.com
+ # I've locked myself away.
+ User-agent: *
+ Disallow: /
+ # The castle is your home now, so you can go anywhere you like.
+ User-agent: Belle
+ Disallow: /west-wing/ # except the west wing!
+ # It's good to be the Prince...
+ User-agent: Beast
+ Disallow:
+
+This file is missing the required blank lines between records.
+However, the intention is clear.

+
+=head1 SYNOPSIS

+ my $rules = WWW::RobotRules::AnyDBM_File->new( 'my-robot/1.0', 'cachefile' );

+
+ # Then just use $ua as usual
+ $res = $ua->request($req);
+
+=head1 DESCRIPTION
+
+This is a subclass of I<WWW::RobotRules> that uses the AnyDBM_File
+package to implement persistent diskcaching of F<robots.txt> and host
+visit information.
+
+The constructor (the new() method) takes an extra argument specifying
+the name of the DBM file to use. If the DBM file already exists, then
+you can specify undef as agent name as the name can be obtained from
+the DBM database.

+=head1 NAME
+
+lwpcook - The libwww-perl cookbook
+
+=head1 DESCRIPTION
+
+This document contain some examples that show typical usage of the
+libwww-perl library. You should consult the documentation for the
+individual modules for more detail.
+
+All examples should be runnable programs. You can, in most cases, test
+the code sections by piping the program text directly to perl.
+
+
+
+=head1 GET
+
+It is very easy to use this library to just fetch documents from the
+net. The LWP::Simple module provides the get() function that return
+the document specified by its URL argument:
+
+ use LWP::Simple;
+ $doc = get 'http://www.linpro.no/lwp/';
+
+or, as a perl one-liner using the getprint() function:
+
+ perl -MLWP::Simple -e 'getprint "http://www.linpro.no/lwp/"'
+
+or, how about fetching the latest perl by running this command:
+
+ perl -MLWP::Simple -e '
+ getstore "ftp://ftp.sunet.se/pub/lang/perl/CPAN/src/latest.tar.gz",
+ "perl.tar.gz"'
+
+You will probably first want to find a CPAN site closer to you by
+running something like the following command:
+
+ perl -MLWP::Simple -e 'getprint "http://www.perl.com/perl/CPAN/CPAN.html"'
+
+Enough of this simple stuff! The LWP object oriented interface gives
+you more control over the request sent to the server. Using this
+interface you have full control over headers sent and how you want to
+handle the response returned.
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $ua->agent("$0/0.1 " . $ua->agent);
+ # $ua->agent("Mozilla/8.0") # pretend we are very capable browser
+
+ $req = HTTP::Request->new(GET => 'http://www.linpro.no/lwp');
+ $req->header('Accept' => 'text/html');
+
+ # send request
+ $res = $ua->request($req);
+
+ # check the outcome
+ if ($res->is_success) {
+ print $res->decoded_content;
+ }
+ else {
+ print "Error: " . $res->status_line . "\n";
+ }
+
+The lwp-request program (alias GET) that is distributed with the
+library can also be used to fetch documents from WWW servers.
+
+
+
+=head1 HEAD
+
+If you just want to check if a document is present (i.e. the URL is
+valid) try to run code that looks like this:
+
+ use LWP::Simple;
+
+ if (head($url)) {
+ # ok document exists
+ }
+
+The head() function really returns a list of meta-information about
+the document. The first three values of the list returned are the
+document type, the size of the document, and the age of the document.
+
+More control over the request or access to all header values returned
+require that you use the object oriented interface described for GET
+above. Just s/GET/HEAD/g.
+
+
+=head1 POST
+
+There is no simple procedural interface for posting data to a WWW server. You
+must use the object oriented interface for this. The most common POST
+operation is to access a WWW form application:
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+
+ my $req = HTTP::Request->new(POST => 'http://www.perl.com/cgi-bin/BugGlimpse');
+ $req->content_type('application/x-www-form-urlencoded');
+ $req->content('match=www&errors=0');
+
+ my $res = $ua->request($req);
+ print $res->as_string;
+
+Lazy people use the HTTP::Request::Common module to set up a suitable
+POST request message (it handles all the escaping issues) and has a
+suitable default for the content_type:
+
+ use HTTP::Request::Common qw(POST);
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+
+ my $req = POST 'http://www.perl.com/cgi-bin/BugGlimpse',
+ [ search => 'www', errors => 0 ];
+
+ print $ua->request($req)->as_string;
+
+The lwp-request program (alias POST) that is distributed with the
+library can also be used for posting data.
+
+
+
+=head1 PROXIES
+
+Some sites use proxies to go through fire wall machines, or just as
+cache in order to improve performance. Proxies can also be used for
+accessing resources through protocols not supported directly (or
+supported badly :-) by the libwww-perl library.
+
+You should initialize your proxy setting before you start sending
+requests:
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $ua->env_proxy; # initialize from environment variables
+ # or
+ $ua->proxy(ftp => 'http://proxy.myorg.com');
+ $ua->proxy(wais => 'http://proxy.myorg.com');
+ $ua->no_proxy(qw(no se fi));
+
+ my $req = HTTP::Request->new(GET => 'wais://xxx.com/');
+ print $ua->request($req)->as_string;
+
+The LWP::Simple interface will call env_proxy() for you automatically.
+Applications that use the $ua->env_proxy() method will normally not
+use the $ua->proxy() and $ua->no_proxy() methods.
+
+Some proxies also require that you send it a username/password in
+order to let requests through. You should be able to add the
+required header, with something like this:
+
+ use LWP::UserAgent;
+
+ $ua = LWP::UserAgent->new;
+ $ua->proxy(['http', 'ftp'] => 'http://username:password@proxy.myorg.com');
+
+ $req = HTTP::Request->new('GET',"http://www.perl.com");
+
+ $res = $ua->request($req);
+ print $res->decoded_content if $res->is_success;
+
+Replace C<proxy.myorg.com>, C<username> and
+C<password> with something suitable for your site.
+
+
+=head1 ACCESS TO PROTECTED DOCUMENTS
+
+Documents protected by basic authorization can easily be accessed
+like this:
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $req = HTTP::Request->new(GET => 'http://www.linpro.no/secret/');
+ $req->authorization_basic('aas', 'mypassword');
+ print $ua->request($req)->as_string;
+
+The other alternative is to provide a subclass of I<LWP::UserAgent> that
+overrides the get_basic_credentials() method. Study the I<lwp-request>
+program for an example of this.
+
+
+=head1 COOKIES
+
+Some sites like to play games with cookies. By default LWP ignores
+cookies provided by the servers it visits. LWP will collect cookies
+and respond to cookie requests if you set up a cookie jar.
+
+ use LWP::UserAgent;
+ use HTTP::Cookies;
+
+ $ua = LWP::UserAgent->new;
+ $ua->cookie_jar(HTTP::Cookies->new(file => "lwpcookies.txt",
+ autosave => 1));
+
+ # and then send requests just as you used to do
+ $res = $ua->request(HTTP::Request->new(GET => "http://www.yahoo.no"));
+ print $res->status_line, "\n";
+
+As you visit sites that send you cookies to keep, then the file
+F<lwpcookies.txt"> will grow.
+
+=head1 HTTPS
+
+URLs with https scheme are accessed in exactly the same way as with
+http scheme, provided that an SSL interface module for LWP has been
+properly installed (see the F<README.SSL> file found in the
+libwww-perl distribution for more details). If no SSL interface is
+installed for LWP to use, then you will get "501 Protocol scheme
+'https' is not supported" errors when accessing such URLs.
+
+Here's an example of fetching and printing a WWW page using SSL:
+
+ use LWP::UserAgent;
+
+ my $ua = LWP::UserAgent->new;
+ my $req = HTTP::Request->new(GET => 'https://www.helsinki.fi/');
+ my $res = $ua->request($req);
+ if ($res->is_success) {
+ print $res->as_string;
+ }
+ else {
+ print "Failed: ", $res->status_line, "\n";
+ }
+
+=head1 MIRRORING
+
+If you want to mirror documents from a WWW server, then try to run
+code similar to this at regular intervals:
+
+ use LWP::Simple;
+
+ %mirrors = (
+ 'http://www.sn.no/' => 'sn.html',
+ 'http://www.perl.com/' => 'perl.html',
+ 'http://www.sn.no/libwww-perl/' => 'lwp.html',
+ 'gopher://gopher.sn.no/' => 'gopher.html',
+ );
+
+ while (($url, $localfile) = each(%mirrors)) {
+ mirror($url, $localfile);
+ }
+
+Or, as a perl one-liner:
+
+ perl -MLWP::Simple -e 'mirror("http://www.perl.com/", "perl.html")';
+
+The document will not be transferred unless it has been updated.
+
+
+
+=head1 LARGE DOCUMENTS
+
+If the document you want to fetch is too large to be kept in memory,
+then you have two alternatives. You can instruct the library to write
+the document content to a file (second $ua->request() argument is a file
+name):
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+
+ my $req = HTTP::Request->new(GET =>
+ 'http://www.linpro.no/lwp/libwww-perl-5.46.tar.gz');
+ $res = $ua->request($req, "libwww-perl.tar.gz");
+ if ($res->is_success) {
+ print "ok\n";
+ }
+ else {
+ print $res->status_line, "\n";
+ }
+
+
+Or you can process the document as it arrives (second $ua->request()
+argument is a code reference):
+
+ use LWP::UserAgent;
+ $ua = LWP::UserAgent->new;
+ $URL = 'ftp://ftp.unit.no/pub/rfc/rfc-index.txt';
+
+ my $expected_length;
+ my $bytes_received = 0;
+ my $res =
+ $ua->request(HTTP::Request->new(GET => $URL),
+ sub {
+ my($chunk, $res) = @_;
+ $bytes_received += length($chunk);
+ unless (defined $expected_length) {
+ $expected_length = $res->content_length || 0;
+ }
+ if ($expected_length) {
+ printf STDERR "%d%% - ",
+ 100 * $bytes_received / $expected_length;
+ }
+ print STDERR "$bytes_received bytes received\n";
+
+ # XXX Should really do something with the chunk itself
+ # print $chunk;
+ });
+ print $res->status_line, "\n";

+=head1 NAME
+
+lwptut -- An LWP Tutorial
+
+=head1 DESCRIPTION
+
+LWP (short for "Library for WWW in Perl") is a very popular group of
+Perl modules for accessing data on the Web. Like most Perl
+module-distributions, each of LWP's component modules comes with
+documentation that is a complete reference to its interface. However,
+there are so many modules in LWP that it's hard to know where to start
+looking for information on how to do even the simplest most common
+things.
+
+Really introducing you to using LWP would require a whole book -- a book
+that just happens to exist, called I<Perl & LWP>. But this article
+should give you a taste of how you can go about some common tasks with
+LWP.
+
+
+=head2 Getting documents with LWP::Simple
+
+If you just want to get what's at a particular URL, the simplest way
+to do it is LWP::Simple's functions.
+
+In a Perl program, you can call its C<get($url)> function. It will try
+getting that URL's content. If it works, then it'll return the
+content; but if there's some error, it'll return undef.
+
+ my $url = 'http://freshair.npr.org/dayFA.cfm?todayDate=current';
+ # Just an example: the URL for the most recent /Fresh Air/ show
+
+ use LWP::Simple;
+ my $content = get $url;
+ die "Couldn't get $url" unless defined $content;
+
+ # Then go do things with $content, like this:
+
+ if($content =~ m/jazz/i) {
+ print "They're talking about jazz today on Fresh Air!\n";
+ }
+ else {
+ print "Fresh Air is apparently jazzless today.\n";
+ }
+
+The handiest variant on C<get> is C<getprint>, which is useful in Perl
+one-liners. If it can get the page whose URL you provide, it sends it
+to STDOUT; otherwise it complains to STDERR.
+
+ % perl -MLWP::Simple -e "getprint 'http://cpan.org/RECENT'"
+
+That is the URL of a plain text file that lists new files in CPAN in
+the past two weeks. You can easily make it part of a tidy little
+shell command, like this one that mails you the list of new
+C<Acme::> modules:
+
+ % perl -MLWP::Simple -e "getprint 'http://cpan.org/RECENT'" \
+ | grep "/by-module/Acme" | mail -s "New Acme modules! Joy!" $USER
+
+There are other useful functions in LWP::Simple, including one function
+for running a HEAD request on a URL (useful for checking links, or
+getting the last-revised time of a URL), and two functions for
+saving/mirroring a URL to a local file. See L<the LWP::Simple
+documentation|LWP::Simple> for the full details, or chapter 2 of I<Perl
+& LWP> for more examples.
+

+ ##########################################################################
+
+
+
+=head2 The Basics of the LWP Class Model
+
+LWP::Simple's functions are handy for simple cases, but its functions
+don't support cookies or authorization, don't support setting header
+lines in the HTTP request, generally don't support reading header lines
+in the HTTP response (notably the full HTTP error message, in case of an
+error). To get at all those features, you'll have to use the full LWP
+class model.
+
+While LWP consists of dozens of classes, the main two that you have to
+understand are L<LWP::UserAgent> and L<HTTP::Response>. LWP::UserAgent
+is a class for "virtual browsers" which you use for performing requests,
+and L<HTTP::Response> is a class for the responses (or error messages)
+that you get back from those requests.
+
+The basic idiom is C<< $response = $browser->get($url) >>, or more fully
+illustrated:
+
+ # Early in your program:
+
+ use LWP 5.64; # Loads all important LWP classes, and makes
+ # sure your version is reasonably recent.
+
+ my $browser = LWP::UserAgent->new;
+
+ ...
+
+ # Then later, whenever you need to make a get request:
+ my $url = 'http://freshair.npr.org/dayFA.cfm?todayDate=current';
+
+ my $response = $browser->get( $url );
+ die "Can't get $url -- ", $response->status_line
+ unless $response->is_success;
+
+ die "Hey, I was expecting HTML, not ", $response->content_type
+ unless $response->content_type eq 'text/html';
+ # or whatever content-type you're equipped to deal with
+
+ # Otherwise, process the content somehow:
+
+ if($response->decoded_content =~ m/jazz/i) {
+ print "They're talking about jazz today on Fresh Air!\n";
+ }
+ else {
+ print "Fresh Air is apparently jazzless today.\n";
+ }
+
+There are two objects involved: C<$browser>, which holds an object of
+class LWP::UserAgent, and then the C<$response> object, which is of
+class HTTP::Response. You really need only one browser object per
+program; but every time you make a request, you get back a new
+HTTP::Response object, which will have some interesting attributes:
+
+=over
+
+=item *
+
+A status code indicating
+success or failure
+(which you can test with C<< $response->is_success >>).
+
+=item *
+
+An HTTP status
+line that is hopefully informative if there's failure (which you can
+see with C<< $response->status_line >>,
+returning something like "404 Not Found").
+
+=item *
+
+A MIME content-type like "text/html", "image/gif",
+"application/xml", etc., which you can see with
+C<< $response->content_type >>
+
+=item *
+
+The actual content of the response, in C<< $response->decoded_content >>.
+If the response is HTML, that's where the HTML source will be; if
+it's a GIF, then C<< $response->decoded_content >> will be the binary
+GIF data.
+
+=item *
+
+And dozens of other convenient and more specific methods that are
+documented in the docs for L<HTTP::Response>, and its superclasses
+L<HTTP::Message> and L<HTTP::Headers>.

+ ##########################################################################
+
+
+
+=head2 Adding Other HTTP Request Headers
+
+The most commonly used syntax for requests is C<< $response =
+$browser->get($url) >>, but in truth, you can add extra HTTP header
+lines to the request by adding a list of key-value pairs after the URL,
+like so:
+
+ $response = $browser->get( $url, $key1, $value1, $key2, $value2, ... );
+
+For example, here's how to send some more Netscape-like headers, in case
+you're dealing with a site that would otherwise reject your request:
+
+
+ my @ns_headers = (
+ 'User-Agent' => 'Mozilla/4.76 [en] (Win98; U)',
+ 'Accept' => 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */*',
+ 'Accept-Charset' => 'iso-8859-1,*,utf-8',
+ 'Accept-Language' => 'en-US',
+ );
+
+ ...
+
+ $response = $browser->get($url, @ns_headers);
+
+If you weren't reusing that array, you could just go ahead and do this:
+
+ $response = $browser->get($url,
+ 'User-Agent' => 'Mozilla/4.76 [en] (Win98; U)',
+ 'Accept' => 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */*',
+ 'Accept-Charset' => 'iso-8859-1,*,utf-8',
+ 'Accept-Language' => 'en-US',
+ );

+If you were only ever changing the 'User-Agent' line, you could just change

+=head2 Enabling Cookies
+
+A default LWP::UserAgent object acts like a browser with its cookies
+support turned off. There are various ways of turning it on, by setting
+its C<cookie_jar> attribute. A "cookie jar" is an object representing
+a little database of all
+the HTTP cookies that a browser can know about. It can correspond to a
+file on disk (the way Netscape uses its F<cookies.txt> file), or it can
+be just an in-memory object that starts out empty, and whose collection of
+cookies will disappear once the program is finished running.
+
+To give a browser an in-memory empty cookie jar, you set its C<cookie_jar>
+attribute like so:
+
+ $browser->cookie_jar({});
+
+To give it a copy that will be read from a file on disk, and will be saved
+to it when the program is finished running, set the C<cookie_jar> attribute
+like this:
+
+ use HTTP::Cookies;
+ $browser->cookie_jar( HTTP::Cookies->new(
+ 'file' => '/some/where/cookies.lwp',
+ # where to read/write cookies
+ 'autosave' => 1,
+ # save it to disk when done
+ ));
+
+That file will be an LWP-specific format. If you want to be access the
+cookies in your Netscape cookies file, you can use the
+HTTP::Cookies::Netscape class:
+
+ use HTTP::Cookies;
+ # yes, loads HTTP::Cookies::Netscape too
+
+ $browser->cookie_jar( HTTP::Cookies::Netscape->new(
+ 'file' => 'c:/Program Files/Netscape/Users/DIR-NAME-HERE/cookies.txt',
+ # where to read cookies
+ ));
+
+You could add an C<< 'autosave' => 1 >> line as further above, but at
+time of writing, it's uncertain whether Netscape might discard some of
+the cookies you could be writing back to disk.

+=head2 Posting Form Data
+
+Many HTML forms send data to their server using an HTTP POST request, which
+you can send with this syntax:
+
+ $response = $browser->post( $url,
+ [
+ formkey1 => value1,
+ formkey2 => value2,
+ ...
+ ],
+ );
+
+Or if you need to send HTTP headers:
+
+ $response = $browser->post( $url,
+ [
+ formkey1 => value1,
+ formkey2 => value2,
+ ...
+ ],
+ headerkey1 => value1,
+ headerkey2 => value2,
+ );
+
+For example, the following program makes a search request to AltaVista
+(by sending some form data via an HTTP POST request), and extracts from
+the HTML the report of the number of matches:
+
+ use strict;
+ use warnings;
+ use LWP 5.64;
+ my $browser = LWP::UserAgent->new;
+
+ my $word = 'tarragon';
+
+ my $url = 'http://www.altavista.com/sites/search/web';
+ my $response = $browser->post( $url,
+ [ 'q' => $word, # the Altavista query string
+ 'pg' => 'q', 'avkw' => 'tgz', 'kl' => 'XX',
+ ]
+ );
+ die "$url error: ", $response->status_line
+ unless $response->is_success;
+ die "Weird content type at $url -- ", $response->content_type
+ unless $response->content_is_html;
+
+ if( $response->decoded_content =~ m{AltaVista found ([0-9,]+) results} ) {
+ # The substring will be like "AltaVista found 2,345 results"
+ print "$word: $1\n";
+ }
+ else {
+ print "Couldn't find the match-string in the response\n";
+ }
+
+
+
+=for comment
+ ##########################################################################
+
+
+
+=head2 Sending GET Form Data
+
+Some HTML forms convey their form data not by sending the data
+in an HTTP POST request, but by making a normal GET request with
+the data stuck on the end of the URL. For example, if you went to
+C<imdb.com> and ran a search on "Blade Runner", the URL you'd see
+in your browser window would be:
+
+ http://us.imdb.com/Tsearch?title=Blade%20Runner&restrict=Movies+and+TV
+
+To run the same search with LWP, you'd use this idiom, which involves
+the URI class:
+
+ use URI;
+ my $url = URI->new( 'http://us.imdb.com/Tsearch' );
+ # makes an object representing the URL
+
+ $url->query_form( # And here the form data pairs:
+ 'title' => 'Blade Runner',
+ 'restrict' => 'Movies and TV',
+ );
+
+ my $response = $browser->get($url);
+
+See chapter 5 of I<Perl & LWP> for a longer discussion of HTML forms
+and of form data, and chapters 6 through 9 for a longer discussion of
+extracting data from HTML.
+
+
+
+=head2 Absolutizing URLs
+
+The URI class that we just mentioned above provides all sorts of methods
+for accessing and modifying parts of URLs (such as asking sort of URL it
+is with C<< $url->scheme >>, and asking what host it refers to with C<<
+$url->host >>, and so on, as described in L<the docs for the URI
+class|URI>. However, the methods of most immediate interest
+are the C<query_form> method seen above, and now the C<new_abs> method
+for taking a probably-relative URL string (like "../foo.html") and getting
+back an absolute URL (like "http://www.perl.com/stuff/foo.html"), as
+shown here:
+
+ use URI;
+ $abs = URI->new_abs($maybe_relative, $base);
+
+For example, consider this program that matches URLs in the HTML
+list of new modules in CPAN:
+
+ use strict;
+ use warnings;
+ use LWP;
+ my $browser = LWP::UserAgent->new;
+
+ my $url = 'http://www.cpan.org/RECENT.html';
+ my $response = $browser->get($url);
+ die "Can't get $url -- ", $response->status_line
+ unless $response->is_success;
+
+ my $html = $response->decoded_content;
+ while( $html =~ m/<A HREF=\"(.*?)\"/g ) {
+ print "$1\n";
+ }
+
+When run, it emits output that starts out something like this:
+
+ MIRRORING.FROM
+ RECENT
+ RECENT.html
+ authors/00whois.html
+ authors/01mailrc.txt.gz
+ authors/id/A/AA/AASSAD/CHECKSUMS
+ ...
+
+However, if you actually want to have those be absolute URLs, you
+can use the URI module's C<new_abs> method, by changing the C<while>
+loop to this:
+
+ while( $html =~ m/<A HREF=\"(.*?)\"/g ) {
+ print URI->new_abs( $1, $response->base ) ,"\n";
+ }
+
+(The C<< $response->base >> method from L<HTTP::Message|HTTP::Message>
+is for returning what URL
+should be used for resolving relative URLs -- it's usually just
+the same as the URL that you requested.)
+
+That program then emits nicely absolute URLs:
+
+ http://www.cpan.org/MIRRORING.FROM
+ http://www.cpan.org/RECENT
+ http://www.cpan.org/RECENT.html
+ http://www.cpan.org/authors/00whois.html
+ http://www.cpan.org/authors/01mailrc.txt.gz
+ http://www.cpan.org/authors/id/A/AA/AASSAD/CHECKSUMS
+ ...
+
+See chapter 4 of I<Perl & LWP> for a longer discussion of URI objects.
+
+Of course, using a regexp to match hrefs is a bit simplistic, and for
+more robust programs, you'll probably want to use an HTML-parsing module
+like L<HTML::LinkExtor> or L<HTML::TokeParser> or even maybe
+L<HTML::TreeBuilder>.

+=head2 Other Browser Attributes
+
+LWP::UserAgent objects have many attributes for controlling how they
+work. Here are a few notable ones:
+
+=over
+
+=item *
+
+C<< $browser->timeout(15); >>
+
+This sets this browser object to give up on requests that don't answer
+within 15 seconds.
+
+
+=item *
+
+C<< $browser->protocols_allowed( [ 'http', 'gopher'] ); >>
+
+This sets this browser object to not speak any protocols other than HTTP
+and gopher. If it tries accessing any other kind of URL (like an "ftp:"
+or "mailto:" or "news:" URL), then it won't actually try connecting, but
+instead will immediately return an error code 500, with a message like
+"Access to 'ftp' URIs has been disabled".
+
+
+=item *
+
+C<< use LWP::ConnCache; $browser->conn_cache(LWP::ConnCache->new()); >>
+
+This tells the browser object to try using the HTTP/1.1 "Keep-Alive"
+feature, which speeds up requests by reusing the same socket connection
+for multiple requests to the same server.
+
+
+=item *
+
+C<< $browser->agent( 'SomeName/1.23 (more info here maybe)' ) >>
+
+This changes how the browser object will identify itself in
+the default "User-Agent" line is its HTTP requests. By default,
+it'll send "libwww-perl/I<versionnumber>", like
+"libwww-perl/5.65". You can change that to something more descriptive
+like this:
+
+ $browser->agent( 'SomeName/3.14 (contact@robotplexus.int)' );
+
+Or if need be, you can go in disguise, like this:
+
+ $browser->agent( 'Mozilla/4.0 (compatible; MSIE 5.12; Mac_PowerPC)' );
+
+
+=item *
+
+C<< push @{ $ua->requests_redirectable }, 'POST'; >>
+
+This tells this browser to obey redirection responses to POST requests
+(like most modern interactive browsers), even though the HTTP RFC says
+that should not normally be done.

+
+=head2 Writing Polite Robots
+
+If you want to make sure that your LWP-based program respects F<robots.txt>
+files and doesn't make too many requests too fast, you can use the LWP::RobotUA
+class instead of the LWP::UserAgent class.
+
+LWP::RobotUA class is just like LWP::UserAgent, and you can use it like so:
+
+ use LWP::RobotUA;
+ my $browser = LWP::RobotUA->new('YourSuperBot/1.34', 'you@yoursite.com');
+ # Your bot's name and your email address
+
+ my $response = $browser->get($url);
+
+But HTTP::RobotUA adds these features:
+
+
+=over
+
+=item *
+
+If the F<robots.txt> on C<$url>'s server forbids you from accessing
+C<$url>, then the C<$browser> object (assuming it's of class LWP::RobotUA)
+won't actually request it, but instead will give you back (in C<$response>) a 403 error
+with a message "Forbidden by robots.txt". That is, if you have this line:
+
+ die "$url -- ", $response->status_line, "\nAborted"
+ unless $response->is_success;
+
+then the program would die with an error message like this:
+
+ http://whatever.site.int/pith/x.html -- 403 Forbidden by robots.txt
+ Aborted at whateverprogram.pl line 1234
+
+=item *
+
+If this C<$browser> object sees that the last time it talked to
+C<$url>'s server was too recently, then it will pause (via C<sleep>) to
+avoid making too many requests too often. How long it will pause for, is
+by default one minute -- but you can control it with the C<<
+$browser->delay( I<minutes> ) >> attribute.
+
+For example, this code:
+
+ $browser->delay( 7/60 );
+
+...means that this browser will pause when it needs to avoid talking to
+any given server more than once every 7 seconds.

+
+=head2 Using Proxies
+
+In some cases, you will want to (or will have to) use proxies for
+accessing certain sites and/or using certain protocols. This is most
+commonly the case when your LWP program is running (or could be running)
+on a machine that is behind a firewall.
+
+To make a browser object use proxies that are defined in the usual
+environment variables (C<HTTP_PROXY>, etc.), just call the C<env_proxy>
+on a user-agent object before you go making any requests on it.
+Specifically:
+
+ use LWP::UserAgent;
+ my $browser = LWP::UserAgent->new;
+
+ # And before you go making any requests:
+ $browser->env_proxy;
+
+For more information on proxy parameters, see L<the LWP::UserAgent
+documentation|LWP::UserAgent>, specifically the C<proxy>, C<env_proxy>,
+and C<no_proxy> methods.
+

+ ##########################################################################
+
+=head2 HTTP Authentication
+
+Many web sites restrict access to documents by using "HTTP
+Authentication". This isn't just any form of "enter your password"
+restriction, but is a specific mechanism where the HTTP server sends the
+browser an HTTP code that says "That document is part of a protected
+'realm', and you can access it only if you re-request it and add some
+special authorization headers to your request".
+
+For example, the Unicode.org admins stop email-harvesting bots from
+harvesting the contents of their mailing list archives, by protecting
+them with HTTP Authentication, and then publicly stating the username
+and password (at C<http://www.unicode.org/mail-arch/>) -- namely
+username "unicode-ml" and password "unicode".
+
+For example, consider this URL, which is part of the protected
+area of the web site:
+
+ http://www.unicode.org/mail-arch/unicode-ml/y2002-m08/0067.html
+
+If you access that with a browser, you'll get a prompt
+like
+"Enter username and password for 'Unicode-MailList-Archives' at server
+'www.unicode.org'".
+
+In LWP, if you just request that URL, like this:
+
+ use LWP;
+ my $browser = LWP::UserAgent->new;
+
+ my $url =
+ 'http://www.unicode.org/mail-arch/unicode-ml/y2002-m08/0067.html';
+ my $response = $browser->get($url);
+
+ die "Error: ", $response->header('WWW-Authenticate') || 'Error accessing',
+ # ('WWW-Authenticate' is the realm-name)
+ "\n ", $response->status_line, "\n at $url\n Aborting"
+ unless $response->is_success;
+
+Then you'll get this error:
+
+ Error: Basic realm="Unicode-MailList-Archives"
+ 401 Authorization Required
+ at http://www.unicode.org/mail-arch/unicode-ml/y2002-m08/0067.html
+ Aborting at auth1.pl line 9. [or wherever]
+
+...because the C<$browser> doesn't know any the username and password
+for that realm ("Unicode-MailList-Archives") at that host
+("www.unicode.org"). The simplest way to let the browser know about this
+is to use the C<credentials> method to let it know about a username and
+password that it can try using for that realm at that host. The syntax is:
+
+ $browser->credentials(
+ 'servername:portnumber',
+ 'realm-name',
+ 'username' => 'password'
+ );
+
+In most cases, the port number is 80, the default TCP/IP port for HTTP; and
+you usually call the C<credentials> method before you make any requests.
+For example:
+
+ $browser->credentials(
+ 'reports.mybazouki.com:80',
+ 'web_server_usage_reports',
+ 'plinky' => 'banjo123'
+ );
+
+So if we add the following to the program above, right after the C<<
+$browser = LWP::UserAgent->new; >> line...
+
+ $browser->credentials( # add this to our $browser 's "key ring"
+ 'www.unicode.org:80',
+ 'Unicode-MailList-Archives',
+ 'unicode-ml' => 'unicode'
+ );
+
+...then when we run it, the request succeeds, instead of causing the
+C<die> to be called.

+=head2 Accessing HTTPS URLs
+
+When you access an HTTPS URL, it'll work for you just like an HTTP URL
+would -- if your LWP installation has HTTPS support (via an appropriate
+Secure Sockets Layer library). For example:
+
+ use LWP;
+ my $url = 'https://www.paypal.com/'; # Yes, HTTPS!
+ my $browser = LWP::UserAgent->new;
+ my $response = $browser->get($url);
+ die "Error at $url\n ", $response->status_line, "\n Aborting"
+ unless $response->is_success;
+ print "Whee, it worked! I got that ",
+ $response->content_type, " document!\n";
+
+If your LWP installation doesn't have HTTPS support set up, then the
+response will be unsuccessful, and you'll get this error message:
+
+ Error at https://www.paypal.com/
+ 501 Protocol scheme 'https' is not supported
+ Aborting at paypal.pl line 7. [or whatever program and line]
+
+If your LWP installation I<does> have HTTPS support installed, then the
+response should be successful, and you should be able to consult
+C<$response> just like with any normal HTTP response.
+
+For information about installing HTTPS support for your LWP
+installation, see the helpful F<README.SSL> file that comes in the
+libwww-perl distribution.

+
+=head2 Getting Large Documents
+
+When you're requesting a large (or at least potentially large) document,
+a problem with the normal way of using the request methods (like C<<
+$response = $browser->get($url) >>) is that the response object in
+memory will have to hold the whole document -- I<in memory>. If the
+response is a thirty megabyte file, this is likely to be quite an
+imposition on this process's memory usage.
+
+A notable alternative is to have LWP save the content to a file on disk,
+instead of saving it up in memory. This is the syntax to use:
+
+ $response = $ua->get($url,
+ ':content_file' => $filespec,
+ );
+
+For example,
+
+ $response = $ua->get('http://search.cpan.org/',
+ ':content_file' => '/tmp/sco.html'
+ );
+
+When you use this C<:content_file> option, the C<$response> will have
+all the normal header lines, but C<< $response->content >> will be
+empty.
+
+Note that this ":content_file" option isn't supported under older
+versions of LWP, so you should consider adding C<use LWP 5.66;> to check
+the LWP version, if you think your program might run on systems with
+older versions.
+
+If you need to be compatible with older LWP versions, then use
+this syntax, which does the same thing:
+
+ use HTTP::Request::Common;
+ $response = $ua->request( GET($url), $filespec );
