Asp.net MVC Controller Index method doesn't fire on Redirect from another controller

Question

public ActionResult Index()
    {

        var tickets =
            DependencyContainer.DomainController.ShowTickets();
        if(tickets==null)
        {
            ViewData.Add("Error","Associate not found");
            return RedirectToAction("Index", "Home");//Doesn't fire the index?
        }
        return View();

Home controller method is as follows and only fires on the debugger startup, and after the redirect IF I hit F5.

    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to Home Loans and Insuring Technology Ticketing";
        //if (TempData.ContainsKey(ErrorKey))
        //{
        //    ViewData[ErrorKey] = TempData[ErrorKey];
        //    TempData.Remove(ErrorKey);
        //}
        return View();
    }

Redirect doesn't fire the controller?

Answer 1

1. You must use TempData when redirecting. ViewData will not work when set before a redirect.
2. Do you cache the site index? Does the browser cache it? Look at the request and response with Firebug or Fiddler.
