Axel Boldt <boldt @

CERN server called Webfilter which extends the CERN (now distributed
by W3C) server to have the filtering capability you are looking for.
You can find links to the WebFilter web page via the URLs:

Alternatively you can use the just alpha released 'wwwblock 1.2' URL
http filtering proxy agent that I wrote to front-end the CERN server
(web browser clients are configured to talk to the wwwblock proxy &
it talks to a proxying Web server such as CERN which has connectivity
to the Internet).
You can find the wwwblock 1.2 README file at URLs:
