Re: Preventing data from being reposted?

Cheers, yeah closing and opening the browser was something that I didn't work out straight away, that was frustrating, I'll check out your headers, thanks again for the help, Rory. Jochem Maas wrote:

I'm pretty sure I am looking at cached pages but the problem with this seems to be that some browsers support these header directives and others don't, i.e. Firefox. The following work in IE but not Firefox header("Cache-control: private"); header("Cache-Control: no-store, no-cache, must-revalidate");

I'd guess that should work but maybe the 'private' throws firefox a curveball, anyway here are the headers I use to 'privatise' logged in sessions:

        header("Expires: ".gmdate("D, d M Y H:i:s", strtotime('1-Jan-1980')) . " GMT");
        // always modified
        header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
        // HTTP/1.1
        header("Cache-Control: no-store, no-cache, must-revalidate");
        header("Cache-Control: post-check=0, pre-check=0", false);
        // HTTP/1.0
        header("Pragma: no-cache");
