Chris -
I wanted to come back to this case. 
Why is the above "expected behavior"?
The client is connecting directly as "https://hostname/APP2" and never going directly to the
ROOT app, yet gets both JSESSIONIDs from Tomcat on first connection.  To me, this seems like
a bug.
Only being an admin, I've not fully read the spec, so not sure if the above is really expected
behavior.
Now, it's been doing this since at least Tomcat 6, I have one running now, and I've never
had a problem with it using direct connections.  But now we are front-ending with HaProxy
and going to two backend tomcats, and using the JSESSIONID to support sticky-sessions.  I'm
afraid the multiple cookies is confusing HaProxy. (Yes, I'm going to ask that user community.)
