setSessionTimeout(timeoutValue: Integer) updating;
The setSessionTimeout method of the Application class enables you to dynamically set the timeout period for all Web sessions that are subsequently created.
Use the timeoutValue parameter to specify in minutes the period at which the Web session ends if no requests have been received within that time. By default, Web sessions do not time out.
The maximum time out value is 1439, which corresponds to 23 hours and 59 minutes.
