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.
