Redirect to external URI from ASP.NET MVC controller
If you're talking about ASP.NET MVC then you should have a controller method that returns the following:
return Redirect("http://www.google.com");
Otherwise we need more info on the error you're getting in the redirect. I'd step through to make sure the url isn't empty.
Using JavaScript
public ActionResult Index()
{
return Content("<script>window.location = 'http://www.example.com';</script>");
}
Note: As @Jeremy Ray Brown said , This is not the best option but you might find useful in some situations.
Hope this helps.
