Pragma No Cache. Expiring page. Any alternative?

[rudy23]

Dunno if this the Right palce to post this question but here goes.

I have these two tags in all my pages

<HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"> 

and

"Cache-control: no-store"

The problem is that any page with Post data gets expired. Hence if the user goes to a different page and clicks back he gets a Warning Page Expired.

Is there any workaround to this. All I want to do is for the browser not to store the page in the temp internet files folder and for the Back Button to work on all pages.

Any Help appreciated.
