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.

the external content filtering database the next time someone tries to access that web site. This
