The ProxySG sends to the ICAP server to retrieve the ICAP server's default configuration settings
You can trigger the OPTIONS message either by clicking Sense-Settings button on the Edit ICAP Service Dialog in Configuration > External Services > ICAP of the ProxySG's Managment Console.
Or by executing the sense-settings command from the ProxySG's command line interface (CLI).
