5 and when you search for advice you will find a dozen different StackOverflow threads, each suggesting a different implementation. Overview What is the goal? Typically good error handling consists of: Human friendly error application_error mvc pages Custom error page per error code (e.g.: 404, 403, 500, etc.) Preserving the HTTP error code in the response to avoid search engine indexing Global error logging for unhandled exceptions Error pages and logging in ASP.NET MVC 5 There are many ways of implementing error handling in ASP.NET MVC 5. Usually you will find solutions which involve at least one or a combination of these methods: HandleErrorAttribute Controller.OnException mvc error page Method Application_Error event customErrors element in web.config httpErrors element in web.config Custom HttpModule All these methods have a historical reason and a justifyable use case. There is no golden solution which works for every application. It is good to know the differences in order to better understand which one is applied best. Before going through each method in more detail I would like to explain some basic fundamentals which will hopefully help in understanding the topic a lot easier. ASP.NET MVC Fundamentals The MVC framework is only a HttpHandler plugged into the ASP.NET pipeline. The easiest way to illustrate this is by opening the Global.asax.cs: public class MvcApplication : System.Web.HttpApplication Navigating to the implementation of HttpApplication will reveal the underlying IHttpHandler and IHttpAsyncHandler interfaces: public class HttpApplication : IComponent, IDisposable, IHttpAsyncHandler, IHttpHandler ASP.NET itself is a larger framework to process incoming requests. Even though it could handle incoming requests from different sources, it is almost exclusively used with IIS. It can be extended with HttpModules and HttpHandlers. HttpModules are plugged into the pipeline to process a request at any point of the ASP.NET life cycle. A HttpHandler is responsible for producing a response/output for a request. IIS (Microsoft's web server technology) will create an incom

Years ago, ASP.NET's error handling was one of the major things that made me wonder if ASP.NET MVC could give me something that ASP.NET Web Forms couldn't. Web Forms is based on https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging pages; so if something goes wrong, all that you can do is to redirect the user to another page and explain what the error was or just be generically sorry. ASP.NET Web Forms allow you to map an error page for each possible HTTP status code. You control the mapping through the

Currently in my project I have a controller called Error with action methods HTTPError404(), HTTPError500(), and General(). They all accept a string parameter error. Using handling error asp.net or modifying the code below. What is the best/proper way to pass the data to the Error controller for processing? I would like to have a robust solution as possible. protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); Response.Clear(); HttpException httpException = exception as HttpException; if (httpException != null) { RouteData routeData = new RouteData(); routeData.Values.Add("controller", "Error"); switch (httpException.GetHttpCode()) { case 404: // page not found routeData.Values.Add("action", "HttpError404"); break; case 500: // server error routeData.Values.Add("action", "HttpError500"); break; default: routeData.Values.Add("action", "General"); break; } routeData.Values.Add("error", exception); // clear error on server Server.ClearError(); // at this point how to properly pass route data to error controller? } } c# asp.net asp.net-mvc error-handling user-experience share|improve this question edited Sep 10 '14 at 17:54 Oualid KTATA 52138 asked Jul 23 '09 at 11:07 aherrick 7,7081772115 add a comment| 9 Answers 9 active oldest votes up vote 80 down vote accepted Instead of creating a new route for that, you could just redirect to your controller/action and pass the information via querystring.
