IIRC, draft-75 was the non-working one (the one with data emitted in the payload without being advertised). I'll have to recheck. I believe that -76 was the first http-compliant one. You should try to add "option http-pretend-keep-alive", it will not touch the Connection header. Also, could you please send me a tcpdump capture of the connection from the client to haproxy and one from haproxy to the server ? Please capture full packets using tcpdump -s0! If you can do that for both working and non-working versions, that would be great ! Willy
