The response answers the request with a code (like 200 for success or 404 for not found), headers, and its own optional body.

## Rewriting Requests

When you provide OkHttp with an HTTP request, you’re describing the request at a high-level: _“fetch me this URL with these headers.”_ For correctness and efficiency, OkHttp rewrites your request before transmitting it.

 *
 * @param <REQ> The type of the request
 * @param <REP> The type of the response, which must extend {@code Result<REQ>}
 * @param request The original request that was processed
 * @param result The result of the request, if successful; may be null if an error occurred
 * @param error Any error that occurred during processing; null if the request was successful
 * @since 4.0.0
