   (url-parse "http://www.inria.fr/sophia/teams/indes/index.html")
   (list protocol uinfo host port abspath))
      ⇒ ("http" #f "www.inria.fr" 80 "/sophia/teams/indes/index.html'')
(multiple-value-bind (protocol uinfo host port abspath)
   (url-parse "https://foo:bar@www.inria.fr/sophia/teams/indes/index.html")
   (list protocol uinfo))
      ⇒ ("https" "foo@bar")
