Sorry, I'm not sure I follow you here. JkMount is used to map a path onto a particular worker. Let's say a request comes in for "/your-app" and you have "JkMount /your-app worker1" in your HTTPD configuration. That would instruct mod_jk to take the request and send it to worker1. If a request came in for "/some-other-app", then mod_jk would do nothing because it does not match with what is configured by JkMount. If you have not done so already, I would suggest you go through the docs and setup a playground environment. I think this is a good place to start. https://tomcat.apache.org/connectors-doc/generic_howto/quick.html Hope that helps.
