Re: Polipo web proxy (was Re: Tor and Google Image search)

7) The definition of parent proxy is different between Polipo and
Privoxy. It turns out Privoxy has teh awesoma poweru of being able to
have an HTTP proxy after Tor. This is useful for sites that block Tor,
such as slashdot & wikipedia (for posting), craigslist, IRC, etc etc
etc. I was unable to find a way for Polipo to do this. It made me
sad. Course it aint exactly convenient for Privoxy, but at least it's
there when you absolutely need to start some flame wars on /. ;)
