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

(minutes)

from the 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.

 

 

Reset

Click Reset to return the screen to its last-saved settings.
