Answer 1

web.config Turn off custom errors in system.web configure http errors in system.webServer Create simple error controller to handle those requests ErrorContoller.cs [AllowAnonymous] public class ErrorController : Controller { // GET: Error public ActionResult NotFound() { var statusCode = (int)System.Net.HttpStatusCode.NotFound; Response.StatusCode = statusCode; Response.TrySkipIisCustomErrors = true; HttpContext.Response.StatusCode = statusCode; HttpContext.Response.TrySkipIisCustomErrors = true; return View(); } public ActionResult Error() { Response.StatusCode = (int)System.Net.HttpStatusCode.InternalServerError; Response.TrySkipIisCustomErrors = true; return View(); } } configure routes RouteConfig.cs public static void RegisterRoutes(RouteCollection routes) { //...other routes routes.MapRoute( name: "404-NotFound", url: "NotFound", defaults: new { controller = "Error", action = "NotFound" } ); routes.MapRoute( name: "500-Error", url: "Error", defaults: new { controller = "Error", action = "Error" } ); //..other routes //I also put a catch all mapping as last route //Catch All InValid (NotFound) Routes routes.MapRoute( name: "NotFound", url: "{*url}", defaults: new { controller = "Error", action = "NotFound" } ); } And finally make sure you have views for the controller actions Views/Shared/NotFound.cshtml Views/Shared/Error.cshtml If there are any additional error you want to handle you can follow that pattern and add as needed. This will avoid redirects and maintain the original http error status that was raised.
