here is the issue: very often people close the window/tab without
logging out. I need solution how to "recognize" when [x] is clicked
(or File >> Close) and kill the session before the window/tab is closed.

few years ago, before firefox and tabs, I solved this by javascript
and onClose() as a part of body tag. now, it doesn't work anymore.

any suggestion/opinion/experience?

That event should still fire regardless of whether it's a window, tab
or iframe. It refers to the page closing, not the window. However, any
event that fires when the user leaves a page (either by clicking on a
link or closing the window) is likely to be prevented by popup
blockers, so you can't rely on it working at all.

A sensible session timeout is the only real solution to this "issue",
possibly aided by a periodic keepalive request.

as you said, I was asked by pop-up blocker to allow this "event". I can
use it - in case there is no popup blocker but in general, as you said,
can't rely on this.

session timeout will do the jobe. not exactly the way I want but...

thanks.

You could set the timeout to a low value, and have the browser make AJAX
requests at an interval less than this. If you don't get your session
update request from the browser, you can deem it as crashed or closed.
