Sessions allow you to temporarily store data for the current user so that it can be accessed in later page requests. (e.g. multi-page forms, shopping carts, etc.)
A single secure session cookie is used. The data itself is stored on the server, using PHP's built-in session system.
Sessions will expire when the user closes their browser (deleting the cookie), or 2 hours after their last request.
This can be configured with
sessionDurationMins in your App Settings.
