To set the session timeouts in the Management Console:
Modify the session.timeout and session.cookie_expires entries in the [app:main] section of the configuration file. The session.timeout value defines the number of seconds before an idle session is timed out. The session.cookie_expires is the maximum length that any session can be active before being timed out. All values are in seconds:
session.timeout=1800
session.cookie_expires=43200
