Tomcat Clustering

[Peter Giesin]

Scott,

I have a couple followup questions:

1. Is a load balancer set to use sticky-sesssion enough to meet this  
requirement or do I actually need to cluster the tomcat instances  
which host CAS?
2. Is the Ticket Registry part of CAS or part of the application that  
is being secured? Also if I wanted to add a suffix to the ticket were  
would this be done?

Thanks,
Pete
