Hi Trustin,
Yes i did try to follow the Thread model tutorial. As is evident, its not
clear to me :)
I seem to have missed to understand, One Connector tied with one I/O
handler. Thanks for clearing that up for me.
now, for every session that is created by calling connector.connect(), i
need to attach some application specific data.
Would it be ok to wait on the ConnectFuture object to join() and then add
the data to the session attachment ?
(i ask because, connection setup may take a while and in the meantime i
would have received more requests to forward)
I can imagine its not easy to put up with silly questions :)
appreciate your patience.
