NOTES:
• The Keyword Filter is based on a DNS query. If a network client has
already accessed a website such as http://www.abcxxx.com, then
the website will not be blocked (a DNS cache in the system stores
previously visited websites). To resolve this issue, clear the DNS cache
before setting up the Keyword Filter.
• Web pages compressed using HTTP compression cannot be filtered.
HTTPS pages also cannot be blocked using a keyword filter.
