[jdev] Opensource Jabber HTTP polling servers?

[lightdee at netscape.net]

I am looking into developing an application based on the jabber protocol, and specifically one that pierces firewalls.  After reading JEP-0025, I still have some questions about how it all works:

- I assume jabber clients which implements JEP-0025 send a heartbeat packet every so often.  Are these HTTP connections typically (re)opened for each heartbeat?  I am looking to scale my application to 10K+ users, so would it be better to reopen the socket for a heartbeat or to keep a HTTP 1.1 persistent connection open?

- If i'm running a jabber client over HTTP (instead of socket 5522/tcp)
how often should the client send a heartbeat, since there isn't any way for the jabber server "push" a message to me from another peer in-between sends/heartbeat packets.

- I looked at the list of servers and code libraries at jabber.org, but it
doesn't look like any of the open source ones implement JEP-0025 or any sort of firewall-piercing technology.  Could someone confirm this?  If there are any, I'd like to get ahold of the code and see how they do it.
