Tracking active sessions over a restart?

[Scott Ganyo]

I'm confused over the appropriate way to track user sessions across restarts
of the servlet engine.  I've been using SessionListeners and
AttributeListeners to track the status of user sessions in my application,
but I've found them to be unreliable when I restart Tomcat and persistent
sessions are enabled.  Is there a way to ensure that I can track the correct
list of active sessions regardless of restarts, etc?

Thanks,
Scott
