=head1 NAME
Net::HTTPS - Low-level HTTP over SSL/TLS connection (client)
=head1 VERSION
version 6.18
=head1 DESCRIPTION
The C<Net::HTTPS> is a low-level HTTP over SSL/TLS client. The interface is the same
as the interface for C<Net::HTTP>, but the constructor takes additional parameters
as accepted by L<IO::Socket::SSL>. The C<Net::HTTPS> object is an C<IO::Socket::SSL>
too, which makes it inherit additional methods from that base class.
For historical reasons this module also supports using C<Net::SSL> (from the
Crypt-SSLeay distribution) as its SSL driver and base class. This base is
automatically selected if available and C<IO::Socket::SSL> isn't. You might
also force which implementation to use by setting $Net::HTTPS::SSL_SOCKET_CLASS
before loading this module. If not set this variable is initialized from the
C<PERL_NET_HTTPS_SSL_SOCKET_CLASS> environment variable.
=head1 ENVIRONMENT
You might set the C<PERL_NET_HTTPS_SSL_SOCKET_CLASS> environment variable to the name
of the base SSL implementation (and Net::HTTPS base class) to use. The default
is C<IO::Socket::SSL>. Currently the only other supported value is C<Net::SSL>.
