URL filtering can focus on all or part of a fully qualified domain name (FQDN), specific path names, specific filenames, specific fi le extensions, or entire specific URLs. Many URL-filtering tools can obtain updated master URL block lists from vendors as well as allow administrators to add or remove URLs from a custom list.
