Scope:
Applies to Barracuda Web Security Flex Service.

Answer:
The Whitelist field on the rule configuration page provides a simple method for creating exceptions to your policy. Websites listed in the Whitelist will be allowed even if the category is selected to be blocked. Conversely, the Blacklist will block a webpage even if the rule would otherwise allow it. However, in order for these to work properly, administrators need to follow certain formatting rules, as described below:

  1. No http// in front.
  2. No www.
  3. No "/" at the end of the domain.
  4. No wildcards.
  5. No Regular Expressions.

Additional Notes:
In some rare circumstances, “www.” is required in the Whitelist/Blacklist entry. This includes situations where the category definitions have an entry for both the www.domain.com and domain.com form of the website. When an entry does not appear to be allowing or blocking properly, it may indicate that both formats are required.
