Anyone used WebCleaner? Looks like it's a standalone web proxy page ad/gif/popup blocker combined with a gzip compressor, and other nifty bits. I use squid + a banner blocker so I don't have need for this right now, but it looks interesting.
I've been using Privoxy which is pretty similiar.
Right now I have Mozilla->DansGuardian->Squid->Privoxy->WWW. (Well actually it's more complicated then that because of transproxy, redir etc)
man, that link looks so familair... *Duck*
