Any way to Expire pages in Netscape?

I am creating a web application and the requirements state that a couple of the JSP's are to expire and not be cached. I have added in the code that sets the Cache-Control, Pragma, Expires in the response, as well as adding in META tags to the HEAD section at the bottom to expire the page as well.

This all works in IE, when I press the back button it shows the page as being expired. But in Netscape I get a popup stating: 'The page you are trying to view contains POSTDATA that has expired from cache. If you resend the data, any action the form carried out (such as a search or online purchase) will be repeated. To resend the data, click OK. Otherwise, click Cancel.'

If the user presses the OK button, then they will see the page that I want to be expired.

Is there anyway to avoid this popup and just show that the page has been expired in Netscape?

Thanks in advance.

I don't think this is possible. I think this just may be one of the differences between the Mozilla Gecko engine, which is what Netscape 6+ uses, and the IE/Win engine.
