Jabber presence server

I am working with some code that requires a URL for the jabber presence server… I am clueless as to what that means. Jabber is otherwise working for me, just in the dark as to how to implement a URL of the form mydomain.com/presence/plugin?

Managed to determine that presence plugin usage seems largely dependent on the flavor of jabber server implemented… ANyone have any ideas??

I don’t know if that exists here. All I see are regular Jabber settings:
username: myusername
server: mydomain.com
port: 5222
