[jdev] processing iq stanza

[Matus Zamborsky]

Hi,
I am reading through rfc 3920 and i am not quite sure about the routing 
of IQ stanzas. I will show what I mean on example:

userA has jid userA at domainA.org
userB has jid userB at domainB.org

if userA sends  iq stanza with my own extension, is it possible for 
server domainA.org to do some useful work(store it in database for 
example) before routing it to server domainB.org?
