getSessionTimeout(): Integer;
The getSessionTimeout method of the Application class returns the Web session timeout value specified for the application.
By default, Web sessions do not time out; that is, the default value of zero (0) indicates infinity.
The Web Options sheet of the Define Application dialog provides the Session Timeout text box, which enables you to specify in minutes the period at which the Web session terminates if no requests have been received within that time.
