you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are handled by ASP.NET and others by IIS. Ideally (and I expect such is the asp.net mvc error handling case with some other frameworks/servers) we would just configure our custom error pages

I created a new ASP.NET MVC 5 application using the standard template in Visual Studio. If I run the site and try to navigate to a resource that does not exist e.g. /foo/bar, I'll get the standard ASP.NET 404 page with the following information: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /foo/bar Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.33440 Not exactly friendly, is it? In this case the error was raised by ASP.NET MVC because it could not find a matching controller and/or action that matched the specified URL. In order to set up a custom 404 error page add the following to web.config insidehere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more http://stackoverflow.com/questions/2480006/what-is-the-difference-between-customerrors-and-httperrors about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging Overflow is a community of 4.7 million programmers, just like you, helping each other.

But would love to know more... –Sunny Mar 19 '10 at 19:51 add a comment| 4 Answers 4 active oldest votes up vote 61 down vote accepted Disclaimer: This is from my experience and not proven fact. Both are used to define error handling for a website, but different software refers to different config elements. customErrors are a legacy (backwards compatable) element, used by Visual Studio Development Server (aka. VSDS or Cassini). httpErrors are the new element which is only used by IIS7. This highlights the possible problem when developing ASP.NET websites while using VSDS instead of the local IIS. Also, refer to this post by myself about how to handle error messages with IIS7, if you wish to have full control of the error output. Summary: Developing in VSDS - use customErrors Publishing the site to IIS6 - use customErrors Publishing the site to IIS7 - use httpErrors. and if you develop with VSDS but publish to IIS7, then i guess u'll need both. share|improve this answer edited Feb 15 '13 at 16:33 Paul DelRe 3,20611322 answered Mar 19 '10 at 23:08 Pure.Krome 37.3k69262457 21 customErrors are for asp.net. httpErrors are for IIS7, and so
it as part of our official documentation for implementing custom error pages, we've decided to sponsor it. Visit elmah.io - Error Management for .NET web applications using ELMAH, powerful search, integrations with Slack and HipChat, Visual Studio integration, API and much more. Custom error pages and global error logging are two elementary and yet very confusing topics in ASP.NET MVC 5. There are numerous ways of implementing error pages in ASP.NET MVC 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 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 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 r
