The default values are no and fail_closed.

where:

•servicename—A configured ICAP service that supports response modification.

•fail_open —If the ProxySG cannot communicate with the ICAP service, the response may be delivered (subject to other policies).

•fail_closed —If the ProxySG cannot communicate with the ICAP service, the request is denied. This is the default and need not be specified to be in effect.
