Net::Proxy::Connector::dual(3)

NAME
Net::Proxy::Connector::dual - Y-shaped Net::Proxy connector

DESCRIPTION
"Net::Proxy::Connecter::dual" is a "Net::Proxy::Connector" that can forward the connection to two distinct services, based on the client connection, before any data is exchanged.

CONNECTOR OPTIONS
This connector can only work as an "in" connector.

The "server_first" and "client_first" options are required: they are hashrefs containing the options necessary to create two "out" "Net::Proxy::Connector" objects that will be used to connect to the requested service.

The "Net::Proxy::Connector::dual" object decides between the two services by waiting during a short timeout. If the client sends some data directly, then it is connected via the "client_first" connector. Otherwise, at the end of the timeout, it is connected via the "server_first" connector.

•   host

    The hostname on which the connector will listen for client connections. Default is "localhost".

•   port

    The port on which the connector will listen for client connections.

•   server_first

    Typically an "out" connector to a SSH server or any service that sends a banner line.

•   client_first

    Typically an "out" connectrot to a web server or SSL server.

•   timeout

    The timeout in seconds (can be decimal) to make a decision. Default is 1 second.

ACKNOWLEDGMENTS
This module is based on a script named sslh, which I wrote with Frederic Ple "<sslh@wattoo.org>" (who had the original insight about the fact that not all servers speak first on the wire).

Frederic wrote a C program, while I wrote a Perl script (based on my experience with connect-tunnel).

Now that "Net::Proxy" is available, I've ported the Perl script to use it.
