On a server I have access to I can successfully set a cookie using PHP however when trying to read the cookie back, the server plays dumb and acts like there is no cookie. I have tested my code (very basic) on two other servers and it works as expected. While I have access to this server with the problem I didn't configure it nor am I the administrator although I can see the Apache and PHP configuration files. Is there any way a firewall (non-personal) could block the cookies from being read by the server? I've tried my test code using Firefox, IE and Opera on windows, and Firefox on Linux and its the same every time. Any thoughts?
