Hi, all, I am relatively new to XMPP world, and have a real problem to be addressed. The problem is, user subscribes to a particular event, when the event happens, system delivers an event notification to the interested users as soon as possible. This is a classical PUB/SUB system. One thing we need to consider is that the user may not stay connected all the time, for example he steps out of wireless coverage. We need to hold the event notification, and when the user becomes connected again, system delivers the event notification to the user. Base on my understanding, PUB/SUB does not define how to process off-line event notification, is there any extension covering this scenario? Any pointer is appreciated.
Thanks for help, /Kaiduan
