Why browser DOESN'T make the redirect though Fiddler shows the opposite

The 'Select' action is called by XmlHttpRequest.

$.ajax(
            {
                async: false,
                url: 'Project/Select/1'                    
            });

The 'Select' action makes redirect

[HttpPost]
    public ActionResult Select(core_User user)
    {
        int id = 0;
        if (int.TryParse(this.RouteData.Values["id"].ToString(), out id))
        {
            Project.Load(id);
            return Redirect("~/general-settings"));
        }
        return new EmptyResult();
    }

In Fiddler I see that redirect request is sent, BUT, the browser DOESN'T make the redirect. It stays on the previous page.

Here is the RAW of the REDIRECT request.

GET http://localhost:26838/general-settings HTTP/1.1

Connection: keep-alive

Where is the problem?

I suggest you follow this example on a similar Stackoverflow question.

It shows you how to use $.ajax in redirect situation. Mind the fact that it is better for you to use window.location.replace() instead of setting location directly.
