Real time messaging framework hub to intercept and retransmit messages for a messaging facility

摘要

Methods and systems are provided for communicating an event from a server to a set of applications via a real time messaging framework hub, which communicates with the applications on individual channels and with the server on a single channel. A polling message is sent to the server and a reply is received. From the reply, it is determined whether the event has occurred. A polling message is received from a client, and a reply is sent containing either the event, if it has occurred, or a null response is sent indicating that the event has not occurred. Limitation of server communication with the hub to a single open channel substantially reduces server overhead.
