Linux Web Filtering with DansGuardian and ClamAV
12 Aug 2004: A web filter is software that can filter the type of content a Web browser
displays. The filter checks the content of a Web page against a set of rules
and replaces any unwanted content with an alternative Web page, usually an “Access
Denied” page. The type of content to be filtered is usually controlled
by a systems administrator. Web filters are used in schools, libraries, homes,
and companies to safeguard personnel from obscene content on the Internet.
