How can firewall settings, like Norton, affect PHP session functionality?

Firewall settings, like Norton, can potentially block the communication between the PHP server and the client, causing issues with PHP session functionality. To solve this issue, you can try adding an exception in the firewall settings to allow communication on the port used for PHP sessions (usually port 80 or 443). 

// Add this line to your PHP code to set the session save path to a custom directory
session_save_path('/path/to/custom/session/directory');
