ASP.NET MVC: Redirecting to an Action on a different application.

I have a copule of MVC apps. I'd like to be able to redirect from one to another? Do I just post to the specific app I'm trying to hit? Is there a way to Html.RedirectToAction on a different app?

From stackoverflow

• you can use RedirectResult:

  public ActionResult SomeAction()
  {
      // do stuff...
      return Redirect("http://myurl.com");
  }
  

• What's stopping you from doing the following inside your action?

  return Redirect("http://www.otherapp.com/product/category");
  

  If you don't want to hard code the http://www.otherapp.com then you could put a configuration setting inside your web.config file for it...?
