Idle Notification is an add-on that notifies the user before their session is about to expire. It enables the following features: - specify a message to be displayed to the user (which may include a count-down timer) before their session expires - set the number of seconds before session termination, at which point the notification is displayed. - add a button to the notification that enables the user to poke the server, thereby extending the session. - add a button to the notification that allow the user to immediately redirect to a different URL (e.g. a logout URL) - add a close button, allowing the user to close the notification without taking any action - specify a different message to be displayed to the user once their session has been terminated - determine whether an outside click when the notification is opened would extend the session - specify a URL to which the page would be automatically redirected upon session termination ### Sponsored development Major pieces of development of this add-on has been sponsored by multiple customers of Vaadin.
