When you click on the Run button in DrRacket, your Web application is launched in the Web server.
The application is available at http://localhost:8000/servlets/standalone.rkt.
The Web Application Scheme language will automatically load this URL in your Web browser.
You may use no-web-browser to prevent the browser from being launched and static-files-path to serve additional static files.
