USER-SPECIFIC CACHE FOR URL FILTERING

Cache storage area for caching data for URL filtering is reserved for each user in a multi-user computing environment. The cache storage area may include a user-specific cache with user cache areas allocated for each particular user. The user cache areas may include entries for data pertaining to URL filtering. For example, the entries may include URL filtering results or references to URL filtering results stored in a general cache. Cache data may include a reference count to indicate the number of users for which the data is being cached. The reference count may be taken into account in the maintenance of the general and user-specific cache areas.
