Overview
This middleware will attempt to return the contents of a file's body from disk in the response. If a file is not found on disk, the request will be delegated to the application stack. This middleware is commonly initialized to serve assets from a server's public/
directory.
This middleware verifies the path to ensure that only files living in the root directory can be rendered. A request cannot produce a directory traversal using this middleware. Only 'GET' and 'HEAD' requests will result in a file being returned.
