In order to minimise the window of opportunity to steal a session, automatically rotate it onto a new session on a frequent basis. This makes a session cookie older than the automatic rollover time less likely to grant access and more likely to be detected. Should a stolen session cookie get rotated while the attacker is using it, the user will be notificed that their session has been taken the next time they open the app if the user re-visits the website before the session is discarded.
