We found this when building our IM client.

The PUT method documented assumes a persistent connection. Most HTTP Proxies
does not allow a persistent connection or block any request responses after
the first. The method actually works if you can get a persistent HTTP
connection.

MSN and Yahoo messengers support HTTP proxies and the way they do this is by
polling every few seconds using a cookie or session request identifier. Yes,
I know this is a horrible way, but try explaining that end-users who are
behind an HTTP proxy.

I don't know what the Jabber folks think of supporting this kind of polling,
but they need to do this if they want to compete with MSN and Yahoo IM
systems.
