I don't get it, your configuration is 100% standard. And the fact that the request is considered invalid should have nothing to do with setting a cookie. What client are you using ? Could you get a tcpdump capture of the exchange between the client and haproxy when the problem happens ? Please use : tcpdump -s0 -npi eth0 host 200.200.1.16 and tcp port 80 -w bug.cap on the haproxy machine, and send me bug.cap after a complete exchange. Also, don't forget to restart your browser in order to ensure it did not maintain any previous cookie. Regards, Willy
