cookie setting in configuration and HTTP/1.1 400 Bad Request

Hi, I have Ecommerce type of web server with dynamic pages that establish session cookie.

If I use the following HAProxy configuration, then the client gets "HTTP/1.1 400 Bad Request " and "Your browser sent a request that this server could not understand." Listen proxy1 200.200.1.16:80

            Mode http
            cookie SERVERID insert indirect
            balance roundrobin
            stats enable
            log 127.0.0.1 local0
            timeout client 30s
            timeout server 30s
            timeout connect 5s
            option tcpka
            server webA 200.200.2.18:80 cookie A

However, if I use the following configuration, it works fine. Listen proxy1 200.200.1.16:80

            Mode http
            balance roundrobin
            stats enable
            log 127.0.0.1 local0
            timeout client 30s
            timeout server 30s
            timeout connect 5s
            option tcpka
            server webA 200.200.2.18:80

However, when I have multiple servers, I do want to use cookie in configuration to look for a particular cookie which will contain a server identifier which should handle the connection. Can any one suggest the correct cookie setting in configuration file? Thanks,
