2.13.3. Authentication Session Control

Fig. 91. Authentication session control settings.

Authentication session control settings are for controlling the lifetimes of user authentication sessions. The Idle timeout setting specifies how long a user can be idle without generating any traffic before being terminated. The Session timeout setting specifies the maximum session lifetime. A zero value in the Idle timeout, Session timeout, or Keep alive interval setting disables the corresponding func- tionality effectively.

In addition, the Router provides a mechanism for detecting whether a user has left unexpectedly by handshaking between JavaScript code in the log-offauthentication page and the Router. The log-offpage notifies the Router periodically to announce user existence. When this mechanism for user exis- tence detection is enabled (Keep alive functionality), the Router will terminate a user if no notifica- tion is received from the log-offpage on the user’s computer within the number of minutes specified by the Keep alive interval setting.

NOTE:

The Log-Offwindow cannot not be shown on a Windows CE-based Pocket PC, it is due to different JavaScript behavior of Pocket Explorer. To support Windows CE-based cli- ents, you have to disable the keep-alive mechanism; otherwise the clients will be termi- nated unexpectedly.

2.13.4.1.Log-On, Log-Off, Authentication Success, and Authentication Failure Pages

Log-on, log-off, authentication success, and authentication failure authentication pages can be cus- tomized in a similar way. You can specify the Text alignment style, page title (HTML title) and the Contents. The Contents setting accepts HTML tagging. Clicking the Preview link shows a test page for you to see the results.
