Category

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. 

URL

This is a web site’s address that the ZyWALL previously checked with 
the external content filtering database.

Remaining Time 
(minutes)

This is the number of minutes left before the URL entry is discarded 
from the cache.

URL Cache 
Setup
Maximum TTL

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.

Apply

Click Apply to save your changes back to the ZyWALL.
