How to avoid “Web page has expired” in IE

问题

I have a page with a form. When I post the form, then I click the previous button in IE, I have an error : "The web page has expired"

As I seen it in this post, I tried :

<meta http-equiv="Cache-Control" content="no-store, no-cache, must-revalidate, post-check=0, pre-check=0">
<meta http-equiv="Pragma" content="no-cache">

Now, I don't have the expired message anymore, but the form just auto revalidate. When I click the previous button, I see I go back to my form page, then I just return to the result page.

Did I do something wrong? I don't understand much in Cache-Control and such.

This is just because of IE caching version. I also found this issue and find some relevant article on this. You can take a look on this - http://support.microsoft.com/kb/183763
