URL rewriting issue through Route.Config - asp.net-mvc

Question

I am able to do the URL rewriting of my MVC Application by using a Route.Config file as below:
//Offline Consult Route
routes.MapRoute(
name: "WrittenStep2",
url: "written/step2/{id}",
defaults: new { controller = "Offline", action = "Step2", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Written",
url: "written",
defaults: new { controller = "Offline", action = "Index" }
);
In the above code, I have Controller as "Offline" and have some actions.
I am able to change the route:
TO: www.abc.com/written
FROM www.abc.com/Offline
My problem is that I am still able to access the URL: www.abc.com/Offline. How can I resolve this issue?
I have tried to deny access of this URL to the users by using the Begin_Request method of Global.asax file.
But after doing that I won't be able to access my methods which I am calling using jQuery Ajax.
$.ajax({
type: "POST",
url: "/Offline/HelloWorld",
data: jsonString,
contentType: "application/json",
...
Is there any way to restrict users from using the same URL?

Answer 1

Try this, it might be helpful for you
...
for the given example, if you want to restrict or navigate users for a specific URL, you can try:
1- include a route for Offline with custom route handler
routes.MapRoute(
"OfflineWithoutParameterRoute",
"Offline"
).RouteHandler = new NewUrlRouteHandler();
routes.MapRoute(
name: "WrittenStep2",
url: "written/step2/{id}",
defaults: new { controller = "Offline", action = "Step2", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Written",
url: "written",
defaults: new { controller = "Offline", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
2- Create your MvcRouteHandler as
public class NewUrlRouteHandler : System.Web.Mvc.MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(System.Web.Routing.RequestContext requestContext)
{
//restrict or navigate to any destination
requestContext.RouteData.Values["controller"] = "Home";
requestContext.RouteData.Values["action"] = "index";
return base.GetHttpHandler(requestContext);
}
}
which you can maintain any approach
so any hit for www.abc.com/Offline will hit to custom handler and any route for www.abc.com/Offline/prm will follow the default route.
I have tried with controller/action you given as an example and it should be helpful for you.
public class OfflineController : Controller
{
// GET: Offline
public ActionResult Index()
{
return View();
}
public ActionResult Step2(int id)
{
return View();
}
public ActionResult HelloWorld(int id)
{
return View();
}
}
