title: Deleting History pages in ASP.net
body: <p>How to delete the history pages in ASP.net?
  In my application when the user logs out, i delete the session variables and expire the cookie(aspxauth and asp_net_sessionId) but however when user clicks on the back button of the browser, user could still see the pages with all the user information on it. However the page cannot interact the server as sessions are not available but expired pages contain demographic information which is an harmful scenario for Security issues.
  Any help appreciated. </p>
