It's posible I'm missing something, but I don't see anyway to get any additional information bout the request's response.

I'm specifically needing two things:

• HTTP Status Code in both onSuccess and onError: Casting the throwable in onError to HttpResponseException will let me call getStatusCode(), but this really isn't the cleanest way to go about it
• Response bodies in onError: RESTful API's frequently send back a response message, along with an HTTP error code.

Bonus: A way to fetch HTTP Response headers in both methods.
