Strophe.ping.js is a plugin to provide XMPP Ping ( XEP-0199 ).

Usage

After you connected sucessfully to the XMPP server you can send a ping to a XMPP client or server:

connection.ping.ping( "[email protected]", success, error, timeout );

You can also add a ping handler to receive pings:

handler = function( ping ){
  ...
  connection.ping.pong( ping );
  ...
  return true;
