There are two ways to manage custom content filtering categories that contain lists of manually added URLs:
- The Visual Policy Manager (VPM): Create an Add Request URL object and enter the lists.
- Use a local database.
Both methods are effectively equivalent for URL lists of typical size. When deciding which solution best suits your environment, consider the following:
- A large list of locally-categorized URLs is more easily managed in a local database, which is a separate file from policy. Managing more than a few hundred URLs in the VPM can become cumbersome. For extremely large lists (more than 100,000 URLs total), the local database performs more efficiently.
- If separation of responsibilities and privileges is required, local database updates can be managed by a user who does not have access to the ProxySG appliance. The installation of the updated database can then be done by a ProxySG appliance administrator. Updates to categories in policy must be performed by a ProxySG appliance administrator.
- Because defined categories must fit into memory, a high-end limit exists. Technically, a local database is limited on by disk space; however, lists reaching up into the millions might cause performance issues.
- Managing a local database requires a Web server to host the database file. If this is not a preferred deployment scenario, use the VPM.
