错误没有'Access-Control-Allow-Origin'标头出现在请求的资源上，同时重定向动作过滤器onActionExecuting

Question

I have an issue in redirecting to the external URL Requirement I want to redirect to an external URL whenever the session is expired.

I have a separate class in which I override the definition of onActionExecuting Action

Here is my Code:

public class SessionExpireAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
       // var redirectUrl = "http://www.google.com";
        var isAjaxRequest = filterContext.HttpContext.Request.IsAjaxRequest();

        if (isAjaxRequest)
        {
            filterContext.Result = new RedirectResult("http://www.google.com");
            return;
        }
        base.OnActionExecuting(filterContext);

    }
}

I Have try almost all the solution that I could find on Stack Over Flow but my problem is not still solved.

Is there is any issue related to pipeline execution of controller filters if so kindly guide me.

Note on console its shows this error

XMLHttpRequest cannot load http://www.google.com/ . No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost:49815 ' is therefore not allowed access.

Edited

 public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var redirectUrl = "http://www.google.com";
        var isAjaxRequest = filterContext.HttpContext.Request.IsAjaxRequest();

        if (isAjaxRequest)
        {
            filterContext.Result = new RedirectToRouteResult(
            new RouteValueDictionary { { "controller", "TestController" }, { "action", "Redirect" } });
            if (filterContext.Result!=null)
            return;
        }
        else
        {
            base.OnActionExecuting(filterContext);
        }

    }

And This is my Controller & Action

 public class TestController : Controller
{
    public ActionResult Redirect()
    {
        return Redirect("http://www.google.com");
    }
}

Thanks in advance.

The first thing you are doing an XMLHttpRequest to a different domain than your page is on. You are getting the error because of same origin for security reasons .

Consider using this Cross-Origin XMLHttpRequest

Also consider Using CORS

Cross-Origin Resource Sharing (CORS) is a W3C spec that allows cross-domain communication from the browser. By building on top of the XMLHttpRequest object, CORS allows developers to work with the same idioms as same-domain requests

EDIT:

As per OP's comment adding this. You redirect to controller action method like below :

filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary
                    {{"controller", "Home"}, {"action", "Index"}});
