I've installed squid proxy server for a company and now they ask me to add blacklisting capabilities for squid.
The most obvious thing that comes to mind is just to find a huge blacklist file on the internet and hook it up to squid configuration as external file.
The other option is to use dedicated solution like squidguard.
I also want to include ability to edit and add entries to a black list through web interface. Although it's not strictly necessarily since I can write it myself with php.
I would welcome any suggestions. My main priority is performance and reliability and if possible I'd like to keep it simple.

It's been quite some time since I've done this. However I worked at a religious boarding school for a while, and they liked to block everything.
I've been looking for the same feed, however I can't seem to find it. The way I did it was to find a list that was maintained on the net, and I wrote a simple bash script to curl the list, echo it out into the appropriate list, and then restart squid.
Simple, I realize, and unless you're an employee there all the time, it might be untenable. Hope the idea helps, but I'm pretty sure you are on the right track.
