Content Filter Cache Screen
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.
You can remove individual entries from the cache. When you do this, the ZyWALL
queries the external content filtering database the next time someone tries to
access that web site. This allows you to check whether a web site’s category has
been changed.

filtering service identified as belonging to a category that was selected to
