In .NET MVC, is there an easy way to check if I'm on the home page?

Question

I need to take a particular action if a user logs in from the home page. In my LogOnModel, I have a hidden field:

@Html.Hidden(\"returnUrl\", Request.Url.Absolut

You can get the current URL via

string controller = (string)ViewContext.RouteData.Values["controller"];
string action = (string)ViewContext.RouteData.Values["action"];
string url = Url.Action(action, controller);

You can do this in an HtmlHelper or in the controller that renders the login view.

Store url in a hidden field as you did, then in your post action:

[HttpPost]
public ActionResult LogOnInt(LogOnModel model)
{
   // Create your home URL
   string homeUrl = Url.Action("Index", "Home");
   if (model.referrer == homeUrl)
   {
      return Json(new { redirectToUrl = @Url.Action("Index","Home")});
   }
 }

The benefit of using Url.Action is that it will use your route table to generate the URL, meaning if your routes ever change, you won't have to change this code.
