Double checking: is "ws" okay here? ("http" is not allowed)

WebSockets use CONNECT method for both non-secure and secure connection when via
a proxy.

See the step 3 of http://tools.ietf.org/html/rfc6455#section-4.1

     *method = "CONNECT";
     *path = GetHostAndPort(url);
   } else {
     *method = request->method;
     *path = HttpUtil::PathForRequest(url);
   }
 }
