$session

$session is a session object that manages arbitrary data during a session. The scope is the duration of the session. Arbitrary properties can be added and retrieved as well as parameters.

Note

• Cookies are required for session use. Please check your browser settings.
• Note that an error will occur if the memory limit in the action is reached when setting data in $session.
• When Buffer type data is set in $session, it is stored as JSON (text data) such as [{”data“:{”type“: ‘Buffer’, ‘data’:[0, 1, …]}, ‘filename’: ‘xxxxxx.xxx’, ‘filesize’:xxxxxx}].
  To treat the stored data as Buffer type data, the value of the data key must be obtained from $session and converted to Buffer.

Session Duration

For authentication applications
Session duration depends on whether "Remember Me" is checked or not.

If checked, the maximum session duration is 14 days.
If not checked, the maximum session duration is 8 hours.

Note

• Please note that if you sign in with a different browser than the one you are already signed in with, the session object of the browser you are already signed in with will be discarded.
• If a session object is defined before authentication, it can be inherited by the session object after authentication.

For unauthenticated applications
The duration of a session can be up to 24 hours from the time the application is displayed. However, even within the duration of the session, it becomes invalid when the browser is closed.
