Re: Web filtering

Hi,

I-Gear from URLabs (http://www.urlabs.com/public/) will do exactly what you
want, but it's quite expensive. We looked at it as an ISP but they wanted
silly money for the number of concurrent sessions we have. In a campus
environment it might be more affordable.

Squid has no API that will give you access to the data stream so it's not
possible to write a content filter without hacking the code. I get the
impression that the developers are focussed on the caching performance and
there are no plans to implement such an API.

I believe that the Peregrine team are looking at content filtering
(http://www.cs.wisc.edu/~cao/peregrine.html). My understanding is that
either Peregrine will do the filtering based on a list of words and phrases
you supply, or else the content will be presented in a buffer for third
party filters to use.

Regards,
Simon.
