proxy question.

[paquito]

I want to pass by proxy a request. The code is this:

        $r->proxyreq(1);
        $r->uri("http://myhost.com/index.html");
        $r->filename("proxy:http://myhost.com/index.html")
        $r->handler("proxy-server");
        return OK;

set it in the uri translation phase, but doesn't work. 

Any suggestions?
