Hi, Can you please tell me why do you want to do that? If the user has already been logged out then he/she can never be able to edit the content of the page, because session has got killed on logout. User can only edit the content if he/she is still logged in. In that case why do you want to redirect the user to login page in spite of knowing that he/she is a valid user? Hope it'll help you. Regards Ajatshatru

Hi, Okay, in that case you can do this with a trick from server side. Though you can find numerous examples on related issue with JavaScript, but you can never be sure with them. Trying to track the back button click of browser is never being a good idea. So what you can do is – On page load of every page create a session object and save anything like page name or any such thing and execute any post back request after validation that session object. `Session[“PageName”] = “some value”;` Now whenever you are redirecting the user to a different page destroy that session object. This way if user visits the page by clicking back button of the browser, you can easily redirect them to login page, after checking session object for null. Hope it'll help you. Regards Ajatshatru
