Coordinate Agent Key Management and Session Timeouts

You must coordinate the updating of agent keys and session timeouts or you may invalidate cookies that contain session information. This coordination is critical because the person designing policies in your organization may be different than the person configuring dynamic key rollover.

Session timeouts should be less than or equal to two times the interval configured between Agent key rollovers. If an administrator configures an agent key rollover to occur two times before a session expires, cookies written by the Web Agent before the first key rollover will no longer be valid and users will be re-challenged for their identification before their session terminates.

For example, if you configure key rollover to occur every three hours, you should to set the Maximum Session timeout to six hours or less to ensure that multiple key rollovers do not invalidate the session cookie.
