=head1 NAME
Net::Proxy::Connector::connect_ssl - Create SSL/CONNECT tunnels through HTTP proxies
=head1 SYNOPSIS
# sample proxy using Net::Proxy::Connector::tcp
# and Net::Proxy::Connector::connect_ssl
use Net::Proxy;
# listen on localhost:6789
# and proxy to remotehost:9876 through proxy.company.com:8080
# using the given credentials
my $proxy = Net::Proxy->new(
in => { type => 'tcp', port => '6789' },
out => {
type => 'connect_ssl',
host => 'remotehost',
port => '9876',
proxy_host => 'proxy.company.com',
proxy_port => '8080',
proxy_user => 'jrandom',
proxy_pass => 's3kr3t',
proxy_agent => 'Mozilla/4.04 (X11; I; SunOS 5.4 sun4m)',
},
);
$proxy->register();
Net::Proxy->mainloop();
=head1 DESCRIPTION
C<Net::Proxy::Connecter::connect_ssl> is a C<Net::Proxy::Connector> that
uses the HTTP CONNECT method to ask the proxy to create a tunnel to
an outside server. The data is then encrypted using SSL.
Obviously, you'll need a server that understands SSL (or a proxy using
C<Net::Proxy::Connector::ssl>) at the other end.
This connector is only an "out" connector.
In addition to the options listed below, this connector accepts all
C<SSL_...> options to C<IO::Socket::SSL>. They are transparently passed
through to the appropriate C<IO::Socket::SSL> methods when upgrading
the socket to SSL.
=head1 CONNECTOR OPTIONS
C<Net::Proxy::Connector::connect> accepts the following options:
=head1 C<out>
=over 4
=item * host
The destination host.
=item * port
The destination port.
=item * proxy_host
The web proxy name or address.
=item * proxy_port
The web proxy port.
=item * proxy_user
The authentication username for the proxy.
=item * proxy_pass
The authentication password for the proxy.
=item * proxy_agent
The user-agent string to use when connecting to the proxy.

=head1 AUTHOR
Philippe 'BooK' Bruhat, C<< <book@cpan.org> >>.
=head1 HISTORY
Because C<Net::Proxy> blocks when it tries to connect to itself,
it wasn't possible to pass an SSL-encrypted connection through
a proxy with a single script: you needed one for the SSL encapsulation,
and another one for bypassing the proxy with the C<CONNECT> HTTP method.
See C<Net::Proxy::Connector::connect> and C<Net::Proxy::Connector::ssl>
for details.
