URL This is a web site's address that the ZyWALL previously checked with the external content filtering database. Remaining Time This is the number of minutes left before the URL entry is discarded (minutes) 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. Apply Reset 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 return the screen to its last-saved settings. 202 ZyWALL USG 50 User's Guide
