url_param in configure file

Hi I am using haproxy with 2 web server .

when client send request each time he send query string with parametre username

example : http://192.168.2.106:8022/?username=guest

and my requirement is when I don't want to use cookies when same username come in query string it always sent to the same server .

as log as no server goes down other wise use rondrobin algorithm.

i use url_param in haproxy.conf file

below is my haproxy configuration file setting .

global

       log 127.0.0.1   local0 info
       maxconn 4096
       daemon

defaults
        log     global
        mode    http

        contimeout      5000
