Hi, I guess I found what cause the polipo to fail on cnn live video.
See the tcpdump below, there is two identical GET (in red) in a pipelined request for the same URL. Beats me why MS Mediaplayer do this. It got two identical replies from the polipo.Tthe first is chunked and the second is not, but otherwise identical. connection trace between polipo and windows xp.

To me, it might be legal for the media player to FIN as a way to say: "I have nothing more to send, but still happy to receive". >From a direct connection to cnn, bypass the polipo, cnn gives two different reply to the two pipelined windows request, the first is hundreds of bytes and the second is 4 bytes. The polipo gives the 4 bytes answer to both of the client request. This could be significant in failing the media player.
