My Web pages causes following error on the browser's Back Button, It works fine for firefox but not on IE,
IE Says,
Most likely cause: •The local copy of this webpage is out of date, and the website requires that you download it again.
What you can try: Click on the Refresh button on the toolbar to reload the page. After refreshing, you might need to navigate to the specific webpage again, or re-enter information.
what should be the cause ?
I'm using Django + mod_python + apache as production environment.
how can I eliminate this error or how to trace any help would be appreciated.
