network communication Xacute applets client -> Mii server

Hi all,

I have a rather technical question.

Does anybody know what goes on from a network communication point of view when an applet on a irpt-page gets executed and fetches data from the Mii server?

Do these applets use RMI or some other method?

It's because we might have network issues, and I would like to know how the applets work on network level.

Our architecture is as follows:

On the client an irpt page is displayed in a browser (MSIE). The irpt page contains applets generated by Xacute queries. We also rely a lot on JS.

The client application communicates with the Mii server over the WAN.

So if someone can tell me which ports are used by the applets, would be great!
