  * Users will get this screen if the screen on their browser is in an
 31  
  * invalid state.  For example, if they hit "Back" or "Reload" and
 32  
  * then try to submit old form data.
 33  
  *
 34  
  * If you want one of your screens to check for invalid state
 35  
  * then add a hidden form field called "_session_access_counter"
 36  
  * with the value currently stored in the session.  The
 37  
  * SessionValidator action will check to see if it is an old
 38  
  * value and redirect you to this screen.
