What is auto logout?

The GAS supports an automatic timeout feature which can be configured to display a log out page after a specified time of user inactivity on an application is detected.

When the AUTO_LOGOUT is set, the DVM detects when an application has no user activity. It then waits the number of seconds specified by the TIMEOUT element before triggering an auto logout event and sending the application a log out message.

For Genero Browser Client (GBC) applications, you get a log out page.
For Genero Desktop Client (GDC) applications, you get a pop-up window.

By default the ending page or pop-up window shows the following message when auto logout occurs:

You have been logged out.
