Friends,

In our Global.asax file we implement Session_End() which grabs our own
object and then calls our own logout() method to tidy things up.  Code is
below. (We wrap this in try/catch, but presently ignore exceptions, perhaps
we'll start logging something to help us figure this out.)

RSWeb.RSWebApp webAppInfo = RSWebApp.GetRSWebApp(Session);
webAppInfo.Logout();

But, it appears that our logout isn't reliably being called, and licenses
are being orphaned.  It appears that when a session times-out Session_End()
is not being called.  SO my question...

Is it a good idea for us to assume Session_End will always be called?  In
what situations might we expect it not to get called?  (Process or
application restarts, I would guess, which is fine for us.)

Any words on this will be very much appreciated.  Thank you very much for
anytime you spend on this.
