Hi All,

I would like to know to invoke a function in JavaScript on closing the browser window.I am trying to

invalidate the user's session in JSP when the user unfortunately closes the browser window.

I have tried the following steps

function UnLoad() {
window.alert("on closing");

}

window.onunload=unLoad;

<body onUnload='javascript:UnLoad();'>


but its not working.

Please help me in this issue.

Regards,
Anand Sivathanu

This has been discussed many many times before in this forum. Please SearchFirst.

The result is always the same: you cannot be reliably informed when the browser is closed. You must rely upon the session timeout to allow orphaned sessions to be reclaimed.
