General Setup; Url Content Filter - Draytek Vigor 2200VG User Manual

URL content filter systems are seen as tools that would provide the
cyberspace equivalent of the physical separations that are used to limit
access to some particular materials. In rating a site as objectionable, and
refusing to display it on the user's computer screen, URL content filtering
facilities can be used to prevent children from seeing material that their
parents find objectionable. In preventing access, the URL content filtering
facility acts as an automated version of the convenience-store clerk who
refuses to sell adult magazines to high-school students. The URL content
filtering facilities are also used by businesses to prevent employees from
accessing Internet resources that are either not work related or otherwise
deemed inappropriate.
The name of the URL content filtering comes from checking the content of
the URL strings. Traditional firewall inspects packets based on the fields of
TCP/IP headers, while the URL content filtering checks the URL strings or
the payload of TCP/IP packets. In the Vigor routers, the URL content
filtering facility inspects the URL string and some of HTTP data hiding in the
payload of TCP packets.
