ProxyClient Web Filtering licensing requires that a valid Blue Coat Web Filter (BCWF) database be installed on the Client Manager and a username and password are used to update the BCWF database categories at least once every 30 days. The BCWF license is available with trial and permanent licenses. Even if the Client Manager is being used as a forward proxy, you must download the BCWF database on the Client Manager for licensing purposes.
For ProxyClients to use Web filtering, the Client Manager must get the current BCWF categories at least once every 30 days. If the categories are not updated within 30 days since its last update, BCWF becomes unlicensed and all URL requests are either allowed or blocked, depending on the administrator’s choice for the On expiration option located on the Configuration > ProxyClient > Web Filtering > Policy tab page.
