An application does not always use dynamic code to handle requests and there are plenty ofimage static content to be served as-it-is. For example, flash animations, images and stylesheets etcetera are all served directly without any processing required.

Google' target='_blank'>App Engine does not provide any automatic way manage directory structure and it has to be specified in your app.yaml file. This is how it’s done:

Suppose your main app directory is helloworld and you have a stylesheet named style.css in helloworld/styles. This is how you edit your app.yaml file to map all requests to /styles to helloworld/styles directory. This is actually archived by URL re-writing.
