-//
-// Note: If the provided domain is considered invalid by url.Parse or otherwise
-// returns an empty scheme or host, clients are not re-directed.
-//
-// Example:
-//
-// r := mux.NewRouter()
-// canonical := handlers.CanonicalHost("http://www.gorillatoolkit.org", 302)
-// r.HandleFunc("/route", YourHandler)
-//
-// log.Fatal(http.ListenAndServe(":7000", canonical(r)))
