When you set a cookie in a certain directory, it's not available to directories above it. Therefore, when you start a session in a subdirectory and then redirect to a directory above it, the session cookie is not going to be valid, so neither is the session. However, you could probably use the session functions to set the domain of the cookie to '/' which will make it valid for the entire site. Also, you should use a complete URL in your header() function: Header('Location: http://www.yourdomain.com/file.php'); ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals.
