I run a odoo 12 environment and have a tool installed to make sure that a session expires after a preset time has passed.

However, a page in the browser will remain visible, even when the session has expired.

This is normal behavior, because the browser is not sending/receiving information to the odoo server, when nothing is refreshed in the browser.

Is there some code available to make sure that a page/browser is sent to the login form, when a session expires?
