Rules let you monitor or control how clients interact with the web. You define rules indicating which sites are allowed or disallowed based on content or malware risk, then specify the response to user web requests violating the rule. For each rule, you can create enforcement schedules and throttle web use by limiting connections, bytes, or time. There are two types of rules:
- Global Only
- Group or User-based
Global rules apply one set of rules to everyone. Group or User-based rules apply to different groups of people or even to individual users. To configure Group or User-based rules, you need to configure authentication. Refer to How to Configure Authentication, or if you are deploying a Barracuda Web Security Service Connector, refer to Authentication with the Barracuda Web Security Service Connector.

After You Add or Change Rules
After you add or change rules, web browser cache and caching servers may have content stored locally that makes a rule appear to be working improperly. If this occurs, then the web browser cache should be cleared manually and the cache should be cleared on caching servers.
