extern crate hyper;

            let uri = "http://rust-lang.org".to_string() + &path;
            let mut response = client.get(&uri)
                .header(Connection::close())

            let mut body = String::new();

            proxy_response.send(&body.into_bytes()).unwrap();

Cool, this is helpful!
