handshaking between JavaScript code in the log-off authentication page and the gateway. The log-off
page notifies the gateway periodically to announce user existence. When this mechanism for user ex-
istence detection is enabled (
Keep alive functionality ), the gateway will terminate a user if no notifi-
cation is received from the log-off page on the user’s computer within the number of minutes speci-
fied by the Keep alive interval setting.
NOTE:
A zero value in the Idle timeout , Session timeout , or Keep alive interval setting disables
the corresponding functionality effectively.
NOTE:
The Log-Off window cannot not be shown on a Windows CE-based Pocket PC due to dif-
ferent JavaScript behavior of Pocket Explorer. To support Windows CE-based clients, you have to
disable the keep-alive mechanism; otherwise the clients will be terminated unexpectedly.
