This may have been discussed before and if so please direct me.
I am currently running a Xenforo System over 2 EC2 instances in Amazons AWS. Both instances are located in the same zone and are load balanced with "sticky sessions".
(This prevent's the problem of being logged out by going to a different server in the network. It does this by ensuring you consistently go to the same server past the Load Balancer via a cookie)
Problem: If that zone goes down; our site is down.
I am trying to develop a more redundant and fault tolerant system.
Problem: in a multi zone installation the "sticky session" option in the load balancer does not work.. It is hidden in the background that each zone will have a load balancer that is subsequently Load Balanced which messes up the sticky sessions.
Is there a way with-in Xenforo to Manage Session affinity for multi server installations?
