Hello Geoff. Agreeing with Scott here about EHCache over a DB. We implemented what you describe with a single VIP to our (ACE) load balancer with two CAS servers behind the load balancer and with EHCache instead of a DB for the tickets cache. It's been in place since the first of the year with great response. I've been doing load testing on a new portal in our test environment (same as production with the load balancer and two CAS nodes behind) with 10K logins per hour and CAS response through the load balancer has remained very good. The setup behind the load balancer works very well for us.

We are using a Cisco ACE LB hardware for our setup (ehcache for tickets, json for service registry) that we are rolling into production currently.

While we were discussing it this morning, we stumbled on the question of whether or not CAS will have a problem with all of the connections having the same source IP (the balancer/proxy). Has anyone ever configured CAS like this... with a proxy/load balancer in front of two servers and a central database? Is this a terrible idea, fraught with peril and heartache? Is there a better way to ensure redundancy?
