This cannot be done reliably. Here's why:

*
The user may disable JavaScript so the log-out script will
never execute.

*
The user may not be on-line when they close your web page.

*
Javascript errors elsewhere in the page may prevent the script
executing.

*
The browser may not support the onunload event, or may not fire
it under certain circumstances, so the log-out function will
not execute.

Might it be worth adding "or fall asleep" and the corresponding answer?

And no logging out is necessary, if they leave my site .... alone.
