How to implement node.js to be able to handle 250k connections as comet server (client side we use socket.io)?

Would the use of nginx as proxy/loadbalancer be the right solution? Or will HA-Proxy be the better way? Has anyone real world experience with 100k+ connections and can share his setup? Would a setup like this be the right one (Quad core CPU per server -> start 4 Instances of node.js per Server?):

  nginx (as proxy / load balancing server)
        /               |          \
       /                |           \
      /                 |            \
     /                  |             \
node server #1  node server #2  node server #3
4 instances     4 instances     4 instances

GeoIP and Nginx

I have a nginx with geoip, but it is not working rightly. The issue is the next: Nginx are getting geodata from $_SERVER['REMOTE_ADDR'] instead of $_SERVER['HTTP_X_HAPROXY_IP'], which have the real client ip. So, the reported geodata belongs to my server ip instead of client ip. Does anybody where… >>> More
