XMPP is connected to the server and authentication succeeds

* XMPP features, all requests are implemented by proxy
*
* Because XMPP is data traffic through a Web server, so all the requests are submitted to the server for processing
*
* Server processing is finished, and the agent tells the client to process the results
*
* Official recommendation Appdelegate handle all proxy responses from XMPP servers
