DESCRIPTION
This is the number of the page of entries currently displayed and the total number
of pages of entries. Type a page number to go to or use the arrows to navigate the
pages of entries.
This is the index number of a categorized web site address record.
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.
Click the Delete icon to remove the URL entry 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 uncategorized
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 begin configuring this screen afresh.
