Question

Say I have a controller with an Index Method and a Update Method. After the Update is done I want to redirect to Index(). Should I use return RedirectToAction(‘Index’) or can I just call return Index()? Is there a difference?

public ActionResult Index() {   return View('Index', viewdata); }  public ActionResult Update() {   // do updates   return RedirectToAction('Index'); or   return Index(); } 

Answer 1

Use the redirect otherwise the URL on the client will remain the same as the posted URL instead of the URL that corresponds to the Index action.
