Overriding the URL categories in the Core server only mode
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.
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.
To override the URL categories in the Core server only mode
Use the -o and -i commands to override the URL categorizations by adding URLs to the allow categories list using the XMLModifier tool.
