  <p>I have to create a login and logout page with sessions. Now I have to invalidate the session after a certain interval of time and after clicking logout button. After session expiry time and logout action no one should be access previous pages by clicking back button of browser without again logging.</p>
  
  <p>How can I achieve this?</p>
