Setup 2 webservers with ColdFusion in loadbalanced environment

Hello,

Can anyone give tips re the following:

I need to create a load balanced ColdFusion environment consisting of 2 servers each with a webserver that is connected to it's own CF10 server.

The traffic to the ip adress is encrypted via https.

The load balancer should be able to assign a client session to a specific server and keep it there during the duration of the session - so effectively making it sticky.

What would be the best setup here?

Do I need to create a cluster of 2 CF10 instances and assign the cluster to webserver 1 and webserver 2 so it is stcky? Or else, if I use 2 standalone ColdFusion instances, how can I make sure the sessions are replicated or sticky?

Thanks,

Marc
