DESCRIPTION
This field shows whether access to the web site's URL was blocked or
allowed.
Click the column heading to sort the entries. Point the triangle up to
display the blocked URLs before the URLs to which access was allowed.
Point the triangle down to display the URLs to which access was allowed
before the blocked URLs.
This is a web site's address that the ZyWALL previously checked with
the external content filtering database.
This is the number of minutes left before the URL entry is discarded
from the cache.
Type the maximum time to live (TTL) (1 to 720 hours). This sets how
long the ZyWALL is to keep an entry in the URL cache before discarding
it.
The external content filtering database frequently adds previously un-
categorized web sites and sometimes changes a web site's category.
Setting this limit higher will speed up the processing of web access
requests but will also make it take longer for the ZyWALL to reflect
changes in the external content filtering database.
Click Apply to save your changes back to the ZyWALL.
Click Reset to return the screen to its last-saved settings.
