At the time I last looked into this, the only reliable way was to have an
applet on the client; JavaScript didn't reliably know when the browser was
closed (it could know when somebody moved off the page, but not when the
window or app itself was closed), whereas applets were guaranteed to have
their stop() methods invoked when the page was closed for any reason.
JavaScript may have changed this in a later release (I last looked into this
about two years ago), but I still wouldn't rely on it too much.
