title: ADFS session expires and causes error
body: <p>We use ADFS for our internal applications - users are basically logged in transparently anytime they go to one of our apps.  However, if a user leaves a page open for over an hour then tries to do something on that page (other than navigate to another page), they get an error:</p>
  
  <blockquote>
    <p>This page is accessing information that is not under its control. This poses a security risk. Do you want to continue?</p>
  </blockquote>
  
  <p>It seems like the page is trying to redirect that request to the ADFS server and that is being prevented by the browser.</p>
  
  <p>My question is thus:  How do I catch this situation and get the user to the ADFS server to reauthenticate?</p>
  
  <p>I haven't had any luck finding anything on Google regarding this.</p>
