In the sample example I will have various methods to perform redirects from main page to “About” page of a simple MVC site. In my opinion, there are only 3 cases – 2 goods and one bad – to perform redirection with or without Ajax.


First case:  A sample redirect and a sample link:

The action is

 public ActionResult RedirectToAboutNoAjax()
            return RedirectToAction("About");

and in the View I call in a simple <a href, generated by :

@Html.ActionLink("Redirect no ajax to about", "RedirectToAboutNoAjax", "Home")

When you click the link, the following happens : a 302 Found answer is send to the browser with the new Location. The browser goes to the page requested.

Second case( not good ajax): Call same action from ajax – in hope that ajax will do the redirect alone, without coding further.Modified only the code that calls the action, transforming to ajax.

<a href="javascript:AjaxNotGoodForRedirect('@Url.Action("RedirectToAboutNoAjax", "Home")')">Redirect not good with ajax - returns the page</a>

 What it happens is the same: the ajax code calls the RedirectToAboutNoAjax , that redirects to about – and the result is the page. It is no redirect performed to the page itself – rather, on the ajax itself!And , to proof it, I will show the message of html returned in an message:image

Third case( good with ajax): Call a action that returns the new url as a json data parameter and make javascript know that.The action:

        public ActionResult RedirectToAboutWithAjax()
                //in a real world, here will be multiple database calls - or others
                return Json(new { ok = true, newurl = Url.Action("About") });
            catch (Exception ex)
                //TODO: log
                return Json(new { ok = false, message = ex.Message });

The javascript:

function AjaxGoodRedirect(urlAction) {
            type: "POST", // see
            url: urlAction,
            data: {}, //to send data see more at
            datatype: "JSON",
            contentType: "application/json; charset=utf-8",
            success: function (returndata) {
                if (returndata.ok)
                    window.location = returndata.newurl;


Note: You can combine the returning the RedirectToAction with Json by checking Request.IsAjaxRequest value and returning either FirstCase, either ThirdCase.
