Drugi argument określa czy response is a 302 (temporary) or 301 permanent redirection. Domyślnie jest to false
.
Druga metoda jest na Controller
i jest po prostu wygodną metodą. Ta metoda była już dostępna w wielu wersjach MVC (już od co najmniej 2), ale IIRC, dodanie części stałej do RedirectResult
wydaje mi się, że znalazłem się w MVC 4 (nie pamiętam, że widziałem to w MVC 3).

Po prostu tak, wiesz, stałe przekierowanie dla RedirectResult _is_ w MVC 3. – MiniRagnarok
