Re: cache control at client

Alf I had a similar problem trying to expire pages so that the user received a "Page Expired" message when they clicked on the back button. I discovered that if you set Cache-control to no-cache then Firefox/IE ignore the expires date. The solution that I got working on IE7 was to set Cache-control to must-revalidate and Expires to 1 second into the future. Firefox still didn't do what I wanted and I didn't test IE6. Rich PS: I was doing this through HTTP headers.
