Setting filter rules

The appliance uses filter rules to deny or allow particular URL requests and keep or strip header information. When a URL request is allowed, the appliance will cache and serve the requested document. When a request is denied, the client receives an access denied message.

You can add, delete, and view filter rules.

3 Select filter, and press Enter.

4 Select add rules, and press Enter.

5 Enter a filter rule, and press Enter.

Each rule must have the following format:
