Abstract
Enforcing a policy based at least in part on URL information is disclosed. A uniform resource locator (URL) is received. A portion of the URL, or a transformation thereof, is matched against a bloom filter. Based on a result of the match, a first query is performed. A policy is enforced based at least in part on a category received as a result of a second query. In some cases, the first and second query are the same.
