Keeping track of online users

[Anders Steinlein <an...@steinlein.no>]

Hi!

This might not be a stricly Struts-related question, but as my application
is using Struts and some of you might be interested, I decided to post
here.

I want to keep track of the number of online users in my application. I
know when a user signs in and out, but what about those numerous users who
doesn't explicitly sign out (leaving the session hanging until it
invalidates)? What is the normal way of dealing with this?

I'm running Tomcat 5.0.19 with container managed security (if that
matters) and Struts 1.1.

Thanks for any input.

Regards,
Anders Steinlein
