## Overview

An HTTP response.

The usual HTTP response attributes are available:

- #status_code the HTTP status code
- #status_message the HTTP status message
- #headers the HTTP headers
- #version the HTTP version

The body of the response is returned by #body decoded as the format specified by the that built the response.

Keep in mind that using this `HttpResponse` impose to fully buffer the response body and should be used for payload that can fit in memory.
