Yes, this is a known bug with Polipo 1.0.4 and 126.96.36.199. I believe that it is fixed in the Git trunk, which is unfortunately not ready to be released (and might never be unless a maintainer is found). At any rate, I do not recommend running Polipo as a publicly accessible proxy. While I have made reasonable efforts to ensure that this is safe, Polipo was not designed for that. Regards, -- Juliusz
