31.7 Content Filter Cache Screen

Click Anti-X > 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.

Please see Section 32.3 on page 556 for how to submit a web site that has been incorrectly categorized.
