I sent a mail with a similar content to the list and discussed it on the dev list. The solution is to divide routing from load balancing. The following functionality would be easy:
> a) sends requests with a session cookie for an inactive worker to that > worker but b) sends requests with no session cookie to a local worker But for this you need an apache with tomcat on any node and a loadbalancer which knows what nodes are active. We do this with a simple protocol between loadbalancer and node. The 'local' worker is connected to tomcat on the same node. Is this a possible solution for you? I'm on the way to set up a test cluster and than I will try to patch the lb-worker of mod_jk and send this to tomcat-dev. May be it is valuable for others.
