Resteasy delegate route to another route

I was wondering if there was a way to delegate to another route in RestEasy.

I.e., something along the lines of, begin in a method inside an RS:

@Path("/api")
public class Foo {

    @POST
    @Path("/foo")
    public Response foo() {
        return RestEasy.delegate("GET", "/api/bar");
    }

}

Where delegate would return the exact same response as if I had made an HTTP GET request to api/bar, that is, will fall through the proper RS that handles that route, ideally refilling all the necessary request information (headers, params, payload).

I don't want an HTTP redirect as I want it to be transparent to the api user.

I see from the docs/source that org.jboss.resteasy.spi.HttpRequest interface you have access to has a forward method.

It takes a string which would be the path to your other endpoint, but it doesn't let you change the method type (post to a get). But then again neither does the RequestDispatcher forward method you have access to. You aren't allowed to modify the request or the response.

See here:

So really all you can do is directly call your service method or, use an HTTP client to call other REST endpoint inside foo and then stream that back to the client.
