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. http://benfoster.io/blog/aspnet-mvc-custom-error-pages Ideally (and I expect such is the case with some other frameworks/servers) http://stackoverflow.com/questions/10116804/how-to-return-own-404-custom-page we would just configure our custom error pages in one place and it would just work, no matter how/where the error was raised. Something like:
404 Page Not Found
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 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 Overflow is a community of 4.7 million programmers, just like you, helping each other.

Response.StatusCode = 404; } If I work on the localhost then together with 404 status returned for the page, page displays 'proper error description'. Once I published the same code to the internet all pages with errors are still displayed with 404 status code, but the don't have the content. Instead, they have the standard 404 error message: 404 - File or directory not found. if the line "Response.StatusCode = 404" commented out then the proper page is provided, but it has 200 status code. Question: how to return user-friendly error page that in the same time has 404 error status code? Any thoughts are welcome! Thanks a lot in advance! P.S. ASP.NET 4.0 asp.net http-status-code-404 share|improve this question asked Apr 12 '12 at 2:57 Budda 7,5312087156 I've always done custom 404 pages in the same way. 1) Transfer to error page 2) user friendly page copy and a 404 under the bonnet for robots. One site I'm trying to do this on now I'm having exactly the same problem - if I add "Response.Status" then a standard 404 is displayed - remove the response.status and the page copy appears but returns a 200. My uneducated guess is something changed in .NET4 framework... –Jag Apr 29 '13 at 10:50 add a comment| 5 Answers 5 active oldest votes up vote 8 down vote
