Running a page in a different port in web server in Grails

I am running the grails application in a port 9200 and I have a healthcheck url and the link is http://myapp:9200/healthcheck. I want to run the healthcheck alone in a different port number, for example http://myapp:9300/healthcheck, is there a way to do in grails ? The reason is I want to abstract the health check URL from users.
