You can override the categorization of a URL in a predefined URL category by adding the URL to the URL List Override. URLs that are contained in the URL List Override are always permitted.
When a URL request is submitted, Symantec Protection Engine checks the URL List Override before it checks the categories in the Deny Access list. If it finds a match in the URL List Override, it does not check the Deny Access list categories. The URL List Override functions in the same manner for both audit and filtering mode.
Add only the URLs to the URL List Override that you know contain acceptable material. When you place a URL in the URL List Override, you permit unconditional access to the URL.
You cannot allow or deny access to a URL based on Internet protocol (for example, HTTP, FTP, and HTTPS). When a URL is contained in a local category that is in the Deny Access list, all connections are uniformly blocked.
