DESCRIPTION
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.
