9 * This demonstrates a minimal http server with a second mount that
10 * is protected using a password file and basic auth.
11 *
12 * To keep it simple, it serves the static stuff from the subdirectory
13 * "./mount-origin" of the directory it was started in.
14 *
15 * You can change that by changing mount.origin below.
