Did you set jmvRoute in server.xml?

I'm trying to use jk1.2.20 mod_jk with Apache 1.3 for load balancing two
tomcat services and sticky sessions aren't working.
My application requires authentication, and displays a login on a new
session. When I kill one of the tomcats, the application works fine
(i.e., the authenticated session is retained and used for each
subsequent request). But if both workers are running, mod_jk ping-pongs
between them (which results in new sessions being created on each request).
The thing I think is most revealing is that when I run with only one
worker alive (so the application works), mod_jk is still trying to
round-robin the two workers.
Here's are some excerpts from mod_jk.log that clearly show mod_jk trying
to use both tomcat1 and tomcat2 for the same session. (is "partial
sessionid" a clue??)
What's going on, and how do I fix this?
