I needed clarification on the following. Here is a scenario:
Initially, AOL user has me in his/her roster. I send the SUBSCRIBED packet and he/she sees me online. Now:
AOL User adds goes offline
AOL User Comes back online
How should we handle it? i.e. on receiving a Presence packet from the AOL user, should we also send back a presence pkt? If yes, what type? Should I check for Presence.TYPE or Presence.MODE as being AVAILABLE when the user comes back online?
Also, what is the difference b/w Presence.TYPE or Presence.MODE?
