title: Back button giving error message on login page
body: <p>So I made a login page for our users to manage their accounts, and once logged in it takes them to a user control panel type page. Once they're on that page they can see all the other pages that are available to them. If they click on Page 2 for example, and then press the back button(which would bring them back to that user control panel) they get an error message saying:</p>
  
  <p>Firefox - Document Expired
            This document is no longer available.
  Chrome - Confirm Form Resubmission</p>
  
  <p>IE - Document Expired</p>
  
  <p>If however they go to page 2 and then from page 2 to page 3 and hit the back button, it will bring them back to page 2 without any issue. I hope this makes sense, and thank you for the help in advance.</p>
