I've read that HttpException is the cleanest way to accomplish this, but it's not http status 403 forbidden error when trying to access webservice working for me. I throw the exception from within a page like this: throw new HttpException(403,"You must be logged in to access this resource."); However, this will only give a standard ASP.Net stack trace(with 500 error) when CustomErrors is off. If CustomErrors is on, then this will not redirect to the page I have setup to be displayed when a 403 error occurs. Should I forget about HttpException and instead set all the HTTP codes myself? How do I fix this? The custom errors part of my Web.Config is this:

But when current client already authenticated but not authorized to run specific action - all I need is to just http://stackoverflow.com/questions/2578756/how-to-make-authorize-attribute-return-custom-403-error-page-instead-of-redirect display my general 403 page. Is it possible without moving authorization logic within controller's body? Update: The behavior I need in should be semantically equals to this sketch: public ActionResult DoWork() { if (!NotAuthorized()) { // this should be not redirect, but forwarding return RedirectToAction("403"); } return View(); } so - there should no any redirect and url should be stay the same, but contents of the page should be replaced with 403-page Update 2: I implemented sketch in this way: [HandleError] public class HomeController : Controller { public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View(); } [CustomActionFilter] public ActionResult About() { return View(); } public ActionResult Error_403() { return Content("403"); } } public class CustomActionFilter : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { filterContext.Result = new ContentResult { Content = "403" }; } } And can't get how to properly forward execution to HomeController.Action_403() so it display 403. Update 3: filterContext.Result = new ViewResult() { ViewName = "Error_403" }; so this is an answer on how to render specific view template... but still have no idea how to run another controller - anyway, it's enough good solution. c# .net asp.net-mvc security authorization share|improve this question edited Nov 7 '11 at 12:00 abatishchev 56.8k56214353 asked Apr 5 '10 at 14:04 zerkms
(Forbidden) status code. This usually indicates that the access to the requested resource is denied for some reason and the server cannot proceed. Unlike the 401 Unauthorized status, which http://thechefprogrammer.blogspot.com/2013/04/returning-http-403-forbidden-error-with.html means an unauthorized access, correct credentials will not allow you to view the page. To handle this scenario in ASP.NET MVC we can create a custom helper which must meet the following conditions: It must be http://www.benlesh.com/2012/08/aspnet-web-api-error-handling-http.html easy and straightforward to use It must return a 403 status code along with the Forbidden status It must not perform a redirect but the page URL should stay the same It must display a asp.net mvc custom view to the user My HttpForbiddenResult class inherits from the HttpStatusCodeResult class which already exists in ASP.NET MVC. In this way, the framework will automatically set the status code and the description. The complete code of the class is the following: public class HttpForbiddenResult : HttpStatusCodeResult { public override void ExecuteResult(ControllerContext context) { base.ExecuteResult(context); // creates the ViewResult adding ViewData and TempData parameters ViewResult result = new ViewResult { asp.net raise 403 ViewName = "AccessDenied", ViewData = context.Controller.ViewData, TempData = context.Controller.TempData }; result.ExecuteResult(context); } // calls the base constructor with 403 status code public HttpForbiddenResult() : base(HttpStatusCode.Forbidden, "Forbidden") { } } I have also created a view called AccessDenied within the Shared folder, which contains a custom message for the users who will view the page: @{ ViewBag.Title = "Access Denied"; }
Access Denied
Sorry, the access to this page is denied.
In order to use the helper you need just the following lines of code: public class HomeController : Controller { public ActionResult DoSomething(string taskName) { // access denied if taskName is empty if (string.IsNullOrEmpty(taskName)) return new HttpForbiddenResult(); return View(); } } If you visit the URL for the previous controller without the taskName parameter, you will see the following result: Of course, with little modifications you can create a custom helper for all the HTTP error codes!

EDIT: I actually recommend against a lot of what I'm saying here now. Web API endpoints shoudl always be returning HttpResponseMessage, and those messages could always be created by Request.CreateResponse(); I'll write more on this later. So it seems to me that not a lot of people have figured out what they should be doing when they want to throw an error from their Web API, but give something back to the client that contains some sort of information about what happened. If you're here you might be herebecauseyou've realized that simple throwing any old exception from your Web API results in a "500: Internal Server Error" with exactly nothing in the body of the response that might explain to the client what went wrong. There are a few things at play here. The quick and dirty version is you're probably throwing the wrong type of exception, and returning the wrong type of status code. Let me explain: You need to be throwing HttpResponseException When you throw just any old error, ASP.Net interprets that as an error in the operation of your web application. In other words, it thinks (and rightfully so) that you've experienced an "internal server error". As such, it just sends out a 500 error. You might think, "Well great, but why doesn't it send out the message in my exception? Why can't they do that for me? Shouldn't that be done for me?" Well, actually no, you don't want to send an explanation with a 500 error, but I'll get to that. If you throw an HttpResponseException, ASP.Net knows that you're attempting to throw an error that you'd like to communicate back to the client with specific information. This, however, does not mean that you should use a 500 error, or that there were all of a sudden be a body in with that 500 error. Because there shouldn't
