   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.
