+=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 provide the method
+
+=item m_uri__I<$method> => $string
+
+Matches if the URI's $method method returns the given value.
+
+=item m_header__I<$field> => $string
+
+Matches if either the request or the response have a header $field with the given value.
+
+=item m_response_attr__I<$key> => undef
+
+=item m_response_attr__I<$key> => $string
+
+Matches if the response object has a that key; or the entry has the given value.

+=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 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
+
+HTTP::Cookies::Netscape - access to Netscape cookies files
+
+=head1 SYNOPSIS
+
+ use LWP;
+ use HTTP::Cookies::Netscape;
+ $cookie_jar = HTTP::Cookies::Netscape->new(
+ file => "c:/program files/netscape/users/ZombieCharity/cookies.txt",
+ );
+ my $browser = LWP::UserAgent->new;
+ $browser->cookie_jar( $cookie_jar );
+
+=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.

+
+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.

+=head1 NAME
+
+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.

+=head1 NAME
+
+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-> falls
+into this category, as well as C<Allow>, C<Expires> and
+C<Last-Modified>. RFC 2616 denote 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<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 )
+ $mess->remove_header( $field )
+ $mess->remove_content_headers
+ $mess->header_field_names
+ $mess->scan( \&doit )
+
+ $mess->date
+ $mess->expires
+ $mess->if_modified_since
+ $mess->if_unmodified_since
+ $mess->last_modified
+ $mess->content_type
+ $mess->content_encoding

+=head1 NAME
+
+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.

+=head1 NAME
+
+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
+ Content-Disposition: form-data; name="email"
+
+ gisle@aas.no
+ --6G+f
+ Content-Disposition: form-data; name="gender"
+
+ M
+ --6G+f
+ Content-Disposition: form-data; name="born"
+
+ 1964
+ --6G+f
+ Content-Disposition: form-data; name="init"; filename=".profile"
+ Content-Type: text/plain
+
+ PATH=/local/perl/bin:$PATH
+ export PATH
+
+ --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 ...).

+
+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->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().

+
+HTTP::Status - HTTP Status code processing
+
+=head1 SYNOPSIS
+
+ use HTTP::Status qw(:constants :is status_message);
+
+ if ($rc != HTTP_OK) {
+ print status_message($rc), "\n";
+ }
+
+ if (is_success($rc)) { ... }

+ if (is_redirect($rc)) { ... }
+
+=head1 DESCRIPTION
+
+I<HTTP::Status> is a library of routines for defining and
+classifying HTTP status codes for libwww-perl. Status codes are
+used to encode the overall outcome of a HTTP response message. Codes
+correspond to those defined in RFC 2616 and RFC 2518.
+
+=head1 CONSTANTS
+
+The following constant functions can be used as mnemonic status code
+names. None of these are exported by default. Use the C<:constants>
+tag to import them all.

+
+=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.
