I need to logged out the user after the inactivity of 5 minutes. I tried using
and PageBase class like in this link http://ift.tt/1Dp6UDZ
But inheriting this PageBase class in every page is not possible in my big project. Is there any other method to do the logout after few minutes of inactivity? It should be applicable to whole big project other than writing the code inside each page or inheriting everypage from some base class?
