php session variables problem in Firefox

Question

I set several php session variables in an initial php file. In all other ajax loaded php files the value of those session variables is updated only after refreshing the page. This happens only in Firefox. Does anyone know what may cause this to happen? In IE everything works fine.

Is there session_start() at the top of all your scripts, AJAX or conventional? — Bojangles

Probably the ajax requests are fired after the file has loaded? — hakre

I found a solution. There was a cache issue. Write:

header("Cache-Control: no-cache");
header("Pragma: no-cache");

after

session_start();

in all your conventional scripts.
