Can we delay responding to a XMPP presence subscription ?

Question

I am using a PacketListener to receive XMPP packets.

If I receive the following:

<presence from="[email protected]" to="[email protected]" type="subscribe"/>

is the XMPP server expecting me to respond immediately ?

• Motivation: I want to cache all these subscription requests and allow the recipient to selectively ACCEPT/DENY (à la facebook invitations).
• Is there an API in which I can request for all subscription requests from openfire ?

Answer 1

You do NOT need to reply immediately or even in a given session; the server stores the fact that you have a pending inbound subscription, and will re-inform you of the pending subscription every time you log in. Therefore, there should be no need to request the list either.
