cancel the 'unload' action in 'onbeforeunload' event

[Marcia Gulesian]

What code can I put in the 'onbeforeunload ' event to cancel the 'unload'
action (when user closes browser) and then present the user with an
alert saying that he/she must use the logout button.

....Bwa! Ha Haaaa Ha Haaa... good one!
What? ..You're *serious*?

What happens when the user presses these keys?

...and do they mention exactly how, as opposed
to vaguely waving hands about and espousing how
it *should* be possible? You're the one with
the book Marcia, what does it say?

I would be especially interested to hear how
they propose preventing the user from disconnecting
the cable that connects them to the internet,
or turning the computer off at the wall.

OTOH, I thought the c.l.js FAQ might mention
something about it.. ahh yes,
<http://www.jibbering.c om/faq/#FAQ4_29>
and.. back to where I started. 'No'.

Really?
Post the source that gave you the impression that it could be done
*reliably*.

There's a very big difference between "can be done" and "can be done
reliably".

I can do a lot of things that only work in IE6 with javascript enabled
on a windows box with low security settings. Those things are generally
used in an HTA and are useless for much else. This group assumes cross-
browser internet use unless otherwise specified.
