karanmalhi / worker.properties
Created December 6, 2011 21:18
Used to configure workers
#The list of workers
worker.list=balancer,stats
#The template contains default values. Each worker will inherit
#these values and override the port
# the worker type
worker.template.type=ajp13
#This could also be an IP address. Since all Tomcat instances
#and IIS are installed on the same host, hence "localhost"
