Subject RE: How to keep track of sessions
Date Mon, 02 Sep 2002 16:16:49 GMT
Hi, Mark.

To give my own 2 cents, I use a session listener for exactly the same issue:
Get information how many sessions are active, who is logged on etc.
Currently my application struggles with a memory leak, and I suspect the
vector not being cleaned up thoroughly (my problem :-( ).
