The Server URL configuration option specifies the first part of an absolute URL that Profound UI will use for making AJAX requests from the client-side Profound UI framework to the server-side Profound UI components. This is useful when packaging your applications as a native mobile app using a tool like Apache Cordova. If not specified, relative URL's are used.
pui.serverURL = "http://myapplication.com:8080";
