How to detect when the user closes the browser

Hi,

Does anyone know of a way to detect when the user closes their browser (And only when they close their browser).

The only way I've discovered to do it, is to tie some code to the 'onUnload' event of the HTML body, but of course that gets triggered whenever the page gets unloaded, i.e. on refresh, back, etc, and not just when the user closes the browser.

Any ideas?

Is there some way I could use ASP to my advantage?

Many thanks,

Rob

Try This


<SCRIPT LANGUAGE="JavaScript">
<!--
function RorC() {

var top=self.screenTop;
if (top>9000)
{alert('window was closed')}
else
{alert('window was Refreshed')}
}

//-->
</SCRIPT>

</HEAD>
<BODY BGCOLOR="#FFFFFF" onunload="javascript:if (document.all){RorC()} else {var top=window.outerWidth;if
(top==0) {opener.alert('window was closed')} else {opener.alert('window was Refreshed')}}">

Fortunately that's not a concern for me in this particular instance. But if you do get a chance to try it, please let me know!
