register_globals set to be off when use the back button ...

When use the back button back to a post form submit page, there will be the warning like this.

Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

To resubmit your information and view this Web page, click the Refresh button.

In some of my old web site, when use the back button, I didn't see the warning message like the above. And I am sure the method was "post" too.

And the page expires features was set up no difference.

My Questions is:

Such as the post form page is a search results list. And I want people to be able to back button to this list without the warning on the way. How can I do it?

Thanks!

OK, I found out the problem. click back button to the post form submit page, I have the warning message due to in that page, I have some codes used session set up or check out.

The one without warning message I don't have the session set up codes.

So the session set up codes caused the page to expire, so the warning message shows.

How can I solve this problem? I have to use the session.
