automatic logout from website after some idle time

I have a web application that is automatic logout after 2 to 2:30 hrs of inactivity , i already created MY_Session library to not update existing session while ajax call also set session_update_time to '0' and session_expiration to zero but not working for me.

Please help me from out this issue.

Thankyou

You can use the CodeIgniter is_ajax_request();

To check to see if the request is from Ajax.

You also need to clear the session array.

Make sure that the web page is not being cached.
