CSS files, JavaScript files, as well as images do not change once your application is started, so they are usually referred to as static assets. The most convenient way to serve them is to map a URL path to a directory of your filesystem. Play comes with an Assets controller that does just this. Consider the following route definition:

GET   /assets/*file = "/public",   file)

This route maps the public directory of your application to the assets path of your HTTP layer. This means that, for example, a public/stylesheets/shop.css file is served under the /assets/stylesheets/shop.css URL.
