how to redirect to external url from c# controller

Question

I'm using a c# controller as web-service.

In it I want to redirect the user to an external url.

How do I do it?

Tried:

System.Web.HttpContext.Current.Response.Redirect

but it didn't work.

I don't think you can do that - it's a cross-domain security violation. — Brian Driscoll

Define "as web-service." How is the controller action being accessed? You can send a redirect response, but if that response isn't going to a standard web browser request then it'll probably be ignored. — David

@EladBenda: I'm not sure what a 324 error actually means. I suspect that a JavaScript redirect should also contain the http:// segment of the URL, though. — David

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

I was happy too soon. still doesn't work. I'm calling it from ajax POST.

jrummell Over a year ago

Are you trying to redirect the entire page or just the ajax response?

Elad Benda Over a year ago

is there really a way to create anonymus type like you did? (new {url: "example.com"})

jrummell Over a year ago

Wrong syntax, sorry. It should be new {url = "example.com"}.

@dipievil the javascript should be placed in your view.

If you are using MVC then it would be more appropriate to use RedirectResult instead of using Response.Redirect.

public ActionResult Index() {
        return new RedirectResult("http://www.website.com");
    }

Perfect - beats RedirectToPage

Try this:

return Redirect("http://www.website.com");

note, you cannot use "www.website.com" - you must provide the http:// or https:// syntax

Thank you @markthewizard1234 among all the answers ive browsed, your note was the one thing that set it straight for me. I did not give it a thought as i was using a dynamic redirect to intranet sites.
