HAProxy configuration - how to make a TCP connection sticky (Node.js, socket.io, websocket, FlashSocket)

Question

I have HAProxy installed for the EC2 server, where I run my nodejs two servers on ports 3005 and 3006. We installed this for our multi-player game. we used socket.io for our real-time event updates on the client side and server side. HAProxy works correctly with the "source of balance" (I added a working copy of my HAProxy configuration), the problem with the original balancer is that all events on the same server happen all the time. therefore, I have 40 computers on my network, so all 40 computer events go to port 3005. its not changing the port when I arrive the next day. I would like to configure the TCP connection sticky with TCP mode in haproxy. is there any way to balance rounding? Here I added my current settings files. we are also trying to use cookies,but it does not work in our case, because we used the mode as tcp.

We also have a flash game that was used to load flash policies from port 3843.

Here is my haproxy configuration added.
