View Full Version : Session Timeout

11-24-2005, 01:37 AM
Hi all,

I have a login script in ASP and would like to have a JS message box popup when the users session is about to time out.

So if i have a fixed session of 20min I would like to warn them when there is only 2 mins left before the session times out.

Can this be done?

OK here is what i ended up with

<script language="javascript" type="text/javascript">

var lTime=29*60;
function LogoutTimer() {


var lMins=(lTime-(lTime%60))/60;
var lSecs=lTime%60;

window.status="Auto Logout: " + lMins + " Min " + lSecs + " Sec" ;

//5 min warning
if (lMins==5 & lSecs==0) {
alert('You will be automatilly logged out in 5 minutes. Please save you work now to ensure no work is lost.');

//timeout warning
if (lMins==0 & lSecs==0) {
alert('You session has timed out. You will need to login again. Please make a copy of your work before you do anything else as it may be lost.');
