Why are you using cookies? Try without and see if it works.

Cephers,
I try to use haproxy as a load balancer for my radosgw, but I always got 405 not allowed when I run s3cmd md s3://mys3 on my haproxy node. But it's ok on radosgw node. I think this is related to the DNS server, but I can't find any document to explain it. Please help.

haproxy.cfg
