Proxy uses twisted.web.proxy.ProxyRequest as its request factory.  The
request will have its "process" method called when it has been completely
received.  You can subclass ProxyRequest, set your proxy to use that subclass
as its request factory, and in that subclass, override process to change the
uri before calling the base implementation.  How's that?
