How do you use custom errors and save the response code?

Question

in my hit web.config you can see redirectMode = "ResponseRewrite". I read that I need to save a status code. Unfortunately, as soon as I have, I get:

"An exception occurred while processing your request. In addition, another exception occurred while executing a custom error page for the first exception. The request was completed.

Omitting this variable successfully redirects me to ~ / Error / Index.cshtml, but has an answer of 200. doh. Any direction would be greatly appreciated, thanks.

<system.web> <compilation debug="true" targetFramework="4.5" /> <customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="~/Error/Index"> <error statusCode="404" redirect="~/Error/Index"/> <error statusCode="500" redirect="~/Error/Index"/> </customErrors> <httpRuntime targetFramework="4.5" /> </system.web> <system.webServer> <httpErrors errorMode="Custom" existingResponse="Auto" defaultResponseMode="ExecuteURL"> <remove statusCode="403"/> <remove statusCode="404"/> <remove statusCode="500"/> <error statusCode="403" path="~/Error/Index" responseMode="File"/> <error statusCode="404" path="~/Error/Index" responseMode="File"/> <error statusCode="500" path="~/Error/Index" responseMode="File"/> </httpErrors> </system.webServer> 

In my filterconfig.cs file:

 public class FilterConfig { public static void RegisterGlobalFilters(GlobalFilterCollection filters) { // does this conflict? filters.Add(new HandleErrorAttribute()); } }

I don’t remember where I saw this code or what I changed, but it works fine in my MVC web application.

Web.config

 <system.web> <compilation debug="true" targetFramework="4.5.1" /> <httpRuntime targetFramework="4.5.1" /> <customErrors mode="Off" /> </system.web> 

Global.aspx

 protected void Application_EndRequest(Object sender, EventArgs e) { ErrorConfig.Handle(Context); } 

ErrorConfig.cs

 namespace Web.UI.Models.Errors { public static class ErrorConfig { public static void Handle(HttpContext context) { switch (context.Response.StatusCode) { case 401: Show(context, 401); break; case 404: Show(context, 404); break; case 500: Show(context, 500); break; } } //TODO uncomment 500 error static void Show(HttpContext context, Int32 code) { context.Response.Clear(); var w = new HttpContextWrapper(context); var c = new ErrorController() as IController; var rd = new RouteData(); rd.Values["controller"] = "Error"; rd.Values["action"] = "Index"; rd.Values["id"] = code.ToString(CultureInfo.InvariantCulture); c.Execute(new RequestContext(w, rd)); } } } 

ErrorController

 public class ErrorController : Controller { // GET: Error [HttpGet] public ViewResult Index(Int32? id) { var statusCode = id.HasValue ? id.Value : 500; var error = new HandleErrorInfo(new Exception("An exception with error " + statusCode + " occurred!"), "Error", "Index"); int errorCode = statusCode; ViewBag.error = errorCode; return View("Error"); } } 

ErrorsViewModel

 namespace Web.UI.Models.Errors { public class ErrorViewModel { public string DisplayErrorMessage { get; set; } public string DisplayErrorPageTitle { get; set; } } } 

Then on the page with the message about the shared folder, add

 @model Web.UI.Models.Errors.ErrorViewModel @{ int errorCode = Convert.ToInt32(@ViewBag.error); switch (errorCode) { case 404: ViewBag.Title = "404 Page Not Found"; Html.RenderPartial("~/Views/Shared/ErrorPages/HttpError404.cshtml"); break; case 500: ViewBag.Title = "Error Occurred"; Html.RenderPartial("~/Views/Shared/_Error.cshtml"); break; default: ViewBag.Title = @Model.DisplayErrorPageTitle; Html.RenderPartial("~/Views/Shared/ErrorPages/HttpNoResultsFound.cshtml"); break; } } 

The above returns status 404 for the page not found and 500 for the error, I hope that it helps
