Net::Proxy::Connector::dual - Y-shaped Net::Proxy connector
"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.
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.
The hostname on which the connector will listen for client connections. Default is "localhost".
The port on which the connector will listen for client connections.
Typically an "out" connector to a SSH server or any service that sends a banner line.
Typically an "out" connectrot to a web server or SSL server.
The timeout in seconds (can be decimal) to make a decision. Default is 1 second.

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.
