*  Change custom header prefix:

    ```
    X-Android-Sent-Millis is now OkHttp-Sent-Millis
    X-Android-Received-Millis is now OkHttp-Received-Millis
    X-Android-Response-Source is now OkHttp-Response-Source
    X-Android-Selected-Transport is now OkHttp-Selected-Transport
    ```
 *  Improve cache invalidation for POST-like requests.
 *  Bring MockWebServer into OkHttp and teach it SPDY.

try (Response response = client.newCall(request).execute()) {
  // Consume and discard the response body.
  response.body().source().readByteString();
}

System.out.println("REQUEST 2 (pooled connection)");
try (Response response = client.newCall(request).execute()) {
  // Consume and discard the response body.
  response.body().source().readByteString();
}
```

And the listener prints the corresponding events:

```

labels.profile.placeholder_new_password= Nuova password
labels.profile.placeholder_confirm_new_password= Conferma nuova password
labels.top.search=Cerca
labels.index_title=Fess
labels.index_form_search_btn=Cerca
labels.index_osdd_title=Cerca
labels.index_form_option_btn=Opzioni
labels.index_help=Aiuto
labels.search_options=Opzioni di ricerca
labels.search_options_close=Chiudi

        return "related_content";
    }
