Wt

Hi,

I have a problem to get all my sessions destroyed for any wt app. The problem is reproducible in Chrome/Chromium, not in Iceweasel. I tried this using Wt 3.2.1 and 3.2.3.

If I open up a browser (creates session A), refresh it by pressing control-R (creates session B) and then close it right away before the session timeout of A (deletes session B), session A doesn't get destroyed until I open a third browser (create session C, kills session A).

Is there a way to make sure that session A is killed? It looks like expireSessions() in web/WebController.cpp is only called while there is at least one browser connected, that is why A isn't deleted for me untill session C comes into play (the diff value for A is negative then).

My logs show this:
