session time out....

[eluser]gulan[/eluser]
Sorry it not working....
I am using extJs frame work, so I got some other command to get the Id,
but i have to check id of each window and some toolbars inside that window.

Now i come to know we can do it with http session, check the following code.

HTTP_Session:tart();
HTTP_Session:etExpire(time() + 60 * 60); // expires in one hour
HTTP_Session:etIdle(10 * 60); // idles in ten minutes
if (HTTP_Session::isExpired()) {
// expired
echo('Your session is expired!');
HTTP_Session::destroy();
}
if (HTTP_Session::isIdle()) {
// idle
echo('You've been idle for too long!');
HTTP_Session::destroy();
}
HTTP_Session::updateIdle();




will it work in codeigniter??? what are the changes required????
