This library is not meant for production use. It is based on a snippet on RubyForge and was packaged as gem to make it easily available.
You may use this class, to programmatically set up a quick and simple reverse proxy. I found it useful to implement advanced inspection of an HTTP communication between an uncontrolled client and server.
See WEBrick::HTTPReverseProxyServer for more information.
The code was originally released in 2006 by Richard Kernahan on Rubyforge.
