The Filter Processing Sequence

To understand appliance filtering behavior, you need to know the order in which filtering processes are applied.

1. First, the appliance checks the Bypass list. Requests from IP addresses in the list are always serviced without filtering.
2. Next, the appliance processes the Override list. URLs covered by the IP address masks in the Override list are either always vended or never vended, as specified. They are not affected by other filtering.
3. Finally, the appliance processes the enabled filter services.

For details on how the appliance processes filter categories, see The Categories List.
