A single Java Server Page, AppController.do, is responsible for rendering the Cúram client on the browser. This application controller JSP is why the URL in the browser is always AppController.do and does not change as the user navigates between separate pages within the Cúram application. As a result of this, the back button of the browser is not supported.
It is still possible to request the URL of a specific page in the browser. In this scenario, on receipt of the request, the browser will be automatically redirected to AppController.do which loads the requested page. See Direct Browsing for details.
