public class GenericProxyGenerator
extends ServiceableGenerator

This is a generic HTTP proxy, designed to handle any possible HTTP method, but with a particular bias towards WebDAV. As of now it's pretty unstable, but still it might be a good proof of concept towards a pure HTTP(++) proxy.
TODO: doesn't handle authentication properly
TODO: doesn't handle (and doubt it'll ever will) HTTP/1.1 keep-alive

           throws ProcessingException,
                  SAXException,
                  IOException

Setup this component by getting the (required) "url" parameter and the (optional) "path" parameter. If path is not specified, the request URI will be used and forwarded. TODO: handle query string
