I've got 2 nginx EC2 instances pointing to 2 Unicorn EC2 instances in a round robin load balanced configuration. The two nginx instances are being the Elastic Load Balancer.

Both Unicorn instances have a Redis session_store configured which is in a master/slave configuration with an Elastic IP attached to the master.

I've tried configuring the session stickiness on the load balancer, but sessions are lost on each page refresh.

I'm using the redis-store gem for the session_store configuration and redis support.

Anyone have any ideas as to why this is not working?

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
