no-cache, no-cache Options

[t-a-g]

I have an asp page that MUST be reloaded from the server EVERY TIME.
The other pages in the website can be cached so I do not want to set any site wide settings.

I have added the following to the top of the page:
Response.ExpiresAbsolute = Now() - 1
Response.AddHeader "Cache-Control", "must-revalidate"
Response.AddHeader "Cache-Control", "no-cache"
Response.AddHeader "Pragma", "no-cache"
Response.Expires = -1

When I click away from the page and then click the "back" button, the page MUST reload from the server.
With IE6, IE7 the page reloads from the server.
With Firefox (Pc/MAC), and Safari the page does not reload.

Since I do not access to all of the users browsers, I can not change the settings on the browser.

What do I have to do to FOURCE the page to be reloaded from the SERVER EVERYTIME reguardless of the user's browser?

That's normal. You can't make it happen. IE is the only browser that doesn't maintain page state when pressing the back button, and they're probably going against a standard in doing so. AFAIK must-revalidate only works on HTTPS page.

Edit: see this post from an Opera developer

For starters, "force" doesn't work on the WWW.

Besides, even without the back button, I can open a link in a new window, and then switch back and forth between the two windows. What's the difference between that and using my brower's history to do the same thing?
