Forcing page refresh on click of back button

Question

I've 2 asp.net pages..page A and page B. On clicking a link on page A, user gets redirected to page B.When on page B, if user clicks browser's back button,I need to forcefully invoke page refresh of page A. How do i achieve this functionality? Note:Code needs to be compatible across different browsers...ie IE, firefox, opera, etc

Thanks for reading.

Answer 1

You could set a session variable on page B and check to see if that session variable exists on page A and handle it accordingly.

Answer 2

I'd say the best way to do it is telling the browser not to cache the page.

<%    Page.Response.Expires = 0;   %>

If that doesn't work to your needs, you'd need javascript to force the refresh.

Psuedo code:

if (cookie does not exist)
  set cookie with 10 second expiration
else if cookie exists {
  is cookie expired? {
     set new cookie
     refresh page
   }
}

Answer 3

There is some button property like Autopostback, you can try it and see if ti helps!
