 * This demonstrates a minimal http server with a second mount that
 * is protected using a password file and basic auth.
 *
 * To keep it simple, it serves the static stuff from the subdirectory
 * "./mount-origin" of the directory it was started in.
 *
 * You can change that by changing mount.origin below.
