/**
 * A server that runs on an application that uses web launch, listening for commands from the web

 * it responds with a redirect command. This server can also be used to shut down the launched-web
 * app using a browser. In order for this to work, the application must implement Shutdownable and
 * must be passed into the static get(...) method.
