// The file server is clean, but you can still add middleware to that by wrapping its "assetHandler".

// With this method, unlike StaticWeb("/" , "./public") which is not working by-design anymore,
// all custom http errors and all routes are working fine with a file server that is registered
// to the root path of the server.
