 *  **The Apache HTTP client and HttpURLConnection APIs are deprecated.** They
    continue to work as they always have, but we're moving everything to the new
    OkHttp 3 API. The `okhttp-apache` and `okhttp-urlconnection` modules should
    be only be used to accelerate a transition to OkHttp's request/response API.
