Suppose there is a servlet running on a cloudlet. The IP of the cloudlet's host machine is 172.26.85.53. I redirected host port 8088 to VM port 8080 using -redir parameter mentioned in https://github.com/cmusatyalab/elijah-provisioning in order to forward post requests to servlet, but it didn't work. The request url is http://172.26.85.53:8088/app/coreServlet. What is the right url?
