NAME

       HTTP::Proxy::FilterStack - A class to manage filter stacks

DESCRIPTION

       This class is used internally by "HTTP::Proxy" to manage its four filter stacks.

       From the point of view of "HTTP::Proxy::FilterStack", a filter is actually a ("matchsub", "filterobj") pair. The match subroutine
       (generated by "HTTP::Proxy"'s "push_filter()" method) is run against the current "HTTP::Message" object to find out which filters must be
       kept in the stack when handling this message.

       The filter stack maintains a set of buffers where the filters can store data. This data is appended at the beginning of the next chunk of
       data, until all the data has been sent.

METHODS

       The class provides the following methods:

       new( $isbody )
	   Create a new instance of "HTTP::Proxy::FilterStack". If $isbody is true, then the stack will manage body filters (subclasses of
	   "HTTP::Proxy::BodyFilter").

       select_filters( $message )
	   $message is the current "HTTP::Message" handled by the proxy.  It is used (with the help of each filter's match subroutine)

       filter( @args )
	   This method calls all the currently selected filters in turn, with the appropriate arguments.

       filter_last()
	   This method calls all the currently selected filters in turn, to filter the data remaining in the buffers in a single pass.

       will_modify()
	   Return a boolean value indicating if the list of selected filters in the stack will modify the body content. The value is computed from
	   the result of calling "will_modify()" on all selected filters.

       all()
	   Return a list of all filters in the stack.

       eod()
	   Used for END OF DATA bookkeeping.

       push()
	   Push the given "[ match, filterobj ]" pairs at the top of the stack.

       insert( $idx, @pairs )
	   Insert the given "[ match, filterobj ]" pairs at position $idx in the stack.

       remove( $idx )
	   Remove the "[ match, filterobj ]" pair at position $idx in the stack.

NAME

       Net::Proxy::Connector::connect_ssl - Create SSL/CONNECT tunnels through HTTP proxies

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();

DESCRIPTION

       "Net::Proxy::Connecter::connect_ssl" is a "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 "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 "SSL_..." options to "IO::Socket::SSL". They are transparently passed
       through to the appropriate "IO::Socket::SSL" methods when upgrading the socket to SSL.

CONNECTOR OPTIONS

       "Net::Proxy::Connector::connect" accepts the following options:

"out"
       o   host

	   The destination host.

       o   port

	   The destination port.

       o   proxy_host

	   The web proxy name or address.

       o   proxy_port

	   The web proxy port.

       o   proxy_user

	   The authentication username for the proxy.

       o   proxy_pass

	   The authentication password for the proxy.

       o   proxy_agent

	   The user-agent string to use when connecting to the proxy.

HISTORY

       Because "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 "CONNECT" HTTP method.

       See "Net::Proxy::Connector::connect" and "Net::Proxy::Connector::ssl" for details.
