  # > 1024 characters sent in POST data, additionally x-www-form-urlencoded
  # so it's only important that encoding method here return original values
  # correctly when CGI.unescape called against it (in compiler code)

  # finding facts and the 'rest' terminus for caching them.  Thus, we'll
  # compile them and then "cache" them on the server.
