Clearing cache after variables have been passed.

[vcherubini]

Hello:

I am working on a forum and I am having an annoying problem.

Whenever you go to a page, the PHP scripts pass session management variables around along. I also have back and foward form buttons on my page that use the POST method to go back and foward.

When you use the browser buttons to go back and foward, on most pages, you get a Page Has Expired.

I have the following code in my common_header() function, which is called on every page:

[tt]
header ("Cache-Control: no-cache, must-revalidate"
[/tt]

Is that how you do it? I need it so that it clears the cache so that when you go back with the browser buttons, it doesn't try to send variables so that I don't get a Page Has Expired.

I have seen this on other forums, so I know it works.

Any help is always appreciated.

Thanks,
