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");
I put that lot together from trial and error more than anything,
if it sucks then somebody please say something!
1 piece of advice when debugging stuff to do with sessions:
everytime you test whatever it is your doing close all you browser windows (kill the app)
first then open a new browser and then perform the actions you want to test.
and just to be absolutely sure first clear the browser cache.
maybe you are looking at cached pages in your browser?
if 'session_variable=="yes"' equates to true then you should send out
headers that tell the browser not to cache the output (or make it
private/force-revalidation)

google it? Anyway I'll take a look.
