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.

Click a column's heading cell to sort the table entries by that column's criteria. Click the

heading cell again to reverse the sort order.

Select a keyword from the Blocked URL Keywords list, and then click

this button to delete it from that list.

Click OK to save your changes back to the ZyWALL.

Click Cancel to exit this screen without saving your changes.
