Proxying a request

As the mailing list is inactive, this looks like the the only place to ask questions.

What is the easiest way to proxy a request with Jersey? I.e. whatever request a resource implementation receives, it needs to send it further using the Client API.

Do I really need to reconstruct everything (media types, entity, headers) from `UriInfo`, `HttpHeaders` etc. using the Client API? Parse the entities using the readers only for them to be serialized again using the writers?

If there is a `Response` class shared by the server and the client, why isn't there a corresponding `Request` class? (`javax.ws.rs.core.Request` is not that.)

Unless I'm missing something, this looks like an omission in the uniform interface implementation.
