It's interesting to know that ELB-based sticky sessions works for WO. Without session persistence, though, isn't auto-scaling going to be a bit rough? If my session is stuck to an instance that auto-scaling is about to kill, my session is going to disappear, isn't it? Do you handle (or intend to handle) that in some way? Also, are the EC2 instances you're talking about here each running a single servlet app instance, or do you have some other setup for this? > It's easy to get started with a WAR deployment - the only thing you have to > do that isn't built-in is to put your web service resources in the > WEB-INF/static folder and set the base url for them.

Interested parties (like me) could then just grab that file. Thanks for discussing what you're doing here, very interesting. -- Paul Hoadley http://logicsquad.net/
