title: Show Login after User Logsout and Press Back button
body: <p>It's quite common that when User is logged out and pressing back button may land into LoggedIn user pages [last page], though they will not be able to do anything from there.
  But certainly it can be seen as Logged in User page.</p>
  
  <p>One way is to ensure that browsers don't cache the page, setting up header parameters.
  But it can work or can't work depending on browser.</p>
  
  <p>When I have seen Facebook, somehow they implemented this feature that once user is logged out, back button will always asks for login.</p>
  
  <p>How do we achieve this using Javascript/jQuery?</p>
