Click Monitor > Anti-X Statistics > Content Filter > Cache to display the 
Content Filter Cache screen. Use this screen to view and configure your 
ZyWALL’s URL caching. You can also configure how long a categorized web site 
address remains in the cache as well as view those web site addresses to which 
access has been allowed or blocked based on the responses from the external 
content filtering server. The ZyWALL only queries the external content filtering 
database for sites not found in the cache.
