MVC controller supporting AJAX redirection function

Hi, I am learning Ajax + MVC. I figured it would be nice if the controller automatically handles ajax-aware Redirect (). After some digging, I found the code from this one. The code below is completely transparent to the user, the user can simply call Redirect (someUrlString) without worrying about the difference between normal / ajax calls. Makes it very neat and cool.

public abstract class BaseController : System.Web.Mvc.Controller {
    //turn into ajax aware redirect
    protected override RedirectResult Redirect(string url) {
        return new AjaxAwareRedirectResult(url);
    }
}

and...

public class AjaxAwareRedirectResult : RedirectResult {
    public AjaxAwareRedirectResult(string url) : base(url) { }
    public override void ExecuteResult(ControllerContext context) {
        if (context.RequestContext.HttpContext.Request.IsAjaxRequest()) {
            string desturl = UrlHelper.GenerateContentUrl(Url, context.HttpContext);
            JavaScriptResult result = new JavaScriptResult() { 
                                      Script = "window.location='" + desturl + "';" };
            result.ExecuteResult(context);
        }
        else { base.ExecuteResult(context); }
    }
}

However, it is not complete. Task:

RedirectToRouteResult (result of ActionResult) RedirectToAction

not yet (very convenient for T4MVC).
