Hi,

I am actually trying to get sticky session load-balancing with IIS &
tomcat (not apache webserver, client's requirement).

My worker.properties:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
worker.list=3Dtomcat1,tomcat2

worker.tomcat1.type=3Dajp13
worker.tomcat1.host=3Dlocalhost
worker.tomcat1.port=3D8009
worker.tomcat1.lbfactor=3D1
worker.tomcat1.socket_timeout=3D5
worker.tomcat1.recycle_timeout=3D10

worker.tomcat2.type=3Dajp13
worker.tomcat2.host=3Dlocalhost
worker.tomcat2.port=3D8209
worker.tomcat2.lbfactor=3D1
worker.tomcat2.socket_timeout=3D5
worker.tomcat2.recycle_timeout=3D10

worker.loadbalancer.type=3Dlb
worker.loadbalancer.balanced_workers=3Dtomcat1


My uriworkermap.properties:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D
default.worker=3Dtomcat1

/webapp/*.jsp=3D$(default.worker)
/webapp/*.do=3D$(default.worker)


"tomcat1" seems to be hardcoded to be the default worker. So how should
I configure, so that tomcat2 will be used for the load-balancing
redirection too?

Also tomcat1 is specified as a load-balancer worker, does that mean that
if tomcat1 goes down, then load-balancing will cease too?

Session route *must* consists only of alphanumeric characters.
See the:
http://jakarta.apache.org/tomcat/connectors-doc/config/workers.html

Later mod_jk releases will have that as prerequisite so that we
don't need to url encode session routes.

This is not quite correct, although it will work.
You should set worker.list only for workers that
have JkMount directive registered.
Also workers that are member of load balancer
*should* not be listed within worker.list

Mladen.
