I did some google search but not find any detail document described about
combination between HAProxy and Nodejs apps(use socketIO), something for me
to believe that it can work well.
I have another option is Nginx, but just want you guys help me to confirm
that is it possible to use HAproxy as load balancer for Nodejs server farm
(using SocketIO to transfer data)?
Thanks in advance.

I set up a proof of concept using haproxy a few months back. It worked
well. haproxy was listening on port 80 then directing socket traffic to
node and static resource requests to nginx.

For polling transports you can balance source or use cookie based
persistence. I would suggest you use cookie based persistence along with
balance source coz IP based balancing alone doesn't work well when clients
have dynamic address.

HAProxy - load Balancer. Can handle websockets. Basically, haproxy sends websocket traffic to 1 or more node servers. We didn't bother with node cluster. Static requests are forwarded to nginx.
Nginx - serve static assets. Nginx doesn't yet support web sockets. Varnish would be a viable option but nginx will support websocket in the near future.

Same can be achieved using stunnel for ssl termination (or AWS ELB's in
TCPssl mode)
Downside of all this is that you loose the Client IP. None of stud, stunnel
or ELB in TCPssl mode will set the X-Forwarded-For, which caused me to
fallback to xhr and jsonp polling transports and use regular HTTPS
termination sollution.
You also want to watch out if you need stickyness or not, when you need to
keep state in your Node.js server, and you have multiple of them. Keep some
kind of stickyness in sight, or you need to share state between your nodes.

Unfortunately all the work was done on a centos box that no longer exists.
I have a bunch old haproxy conf files hanging around on my desktop like
https://gist.github.com/3227797. I am not sure which conf was the final. I
kept changing the config because I ran into an issue like
https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-s... on
a WIN7 box, but did not recognize it. Below are couple links that I think I
used to get started.
