Configuration - Flask-Session 0.8.0 documentation

In the case of non-permanent server-side sessions, the server has no way to know when the browser is closed and it’s session cookie removed as a result, so it cannot confidently know when to delete the stored session data linked to that browser. This can lead to a large number of stale sessions being stored on the server. To mitigate this somewhat, Flask-Session always sets server-side expiration time using PERMANENT_SESSION_LIFETIME.
