The question is with traffic of tor should be blocked. Outgoing client traffic to the tor network or incoming httpd requests from tor exit nodes ?

Tor is speaking SOCKS5. You need Polipo to speak HTTP on the client side and SOCKS on the server side. I have actively tried to connect to 2 of our SOCKS5 machines (and Tor) via my Squid and I could not succeed. I have even tried Amos' custom squid with SOCKS support and still failed. Can someone explain to me as to how you are connecting to Tor with squid (and consequently having a need to block it)?
