Use this screen to view and configure your device’s URL caching. You can also configure how
long a categorized web site address remains in the cache as well as view those web site
addresses to which access has been allowed or blocked based on the responses from the
external content filtering server. The device only queries the external content filtering database
for sites not found in the cache.
You can remove individual entries from the cache. When you do this, the device queries the
external content filtering database the next time someone tries to access that web site. This
allows you to check whether a web site’s category has been changed.
Please see the device’s User’s Guide for how to submit a web site that has been incorrectly
categorized.
