HAProxy Configuration - How to make TCP connection sticky (Node.js, socket.io, websocket, FlashSocket)

I have setup HAProxy for EC2 server where i'm running my nodejs two server on port 3005 and 3006. we have setup this for our multiplayer game. we have used socket.io for our realtime event update on client side and server side. HAProxy is working correctly with "balance source" (I have added working copy of my HAProxy Configuration), in source balancer problem is that its goes all event on same server each and ever time. so i have 40 computer setup in my network so all 40 computer event goes to 3005 port. its not changing port when i'm coming next day. I would like to setup TCP connection sticky with TCP mode in haproxy. is there any way to do with balance roundrobin? I have added my current setting files here. we also trying to used cookie but its not working in our case because we have used mode as tcp.

Also we have flash game which used to load flash policy from port 3843.

Here added my haproxy configuration.
