Some portal requests are connected to each other and need to be used in sequence. The pattern used in such cases is a Session object. Just like Requests, sessions are represented by an object path, that is returned by the initial CreateSession call of the respective portal. Subsequent calls take the object path of the session they operate on as an argument.

Sessions can be ended from the application side by calling the Close() method on the session. They can also be closed from the service side, in which case the ::Closed signal is emitted on the Session object to inform the application.
