The exception info is lost. I would up storing it in the session in Application_Error() and pulling it back out in the Page_Load() handler of my error page. –BrianK Aug 7 '09 at 2:41 2 That should be the norm in all the documentation. This is so good I see no reason to support the old behaviour anymore. As long as the status code is correct there should be no issue with leaving the original request URL intact (not doing a browser redirect). In fact that is more correct according to HTTP because the response code relates to the reques
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 case with some other http://benfoster.io/blog/aspnet-mvc-custom-error-pages frameworks/servers) 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: Custom 404 error pages When a resource does not exist (either static or dynamic) we should return a 404 HTTP status code. Ideally we should return something a little friendlier to our site visitors than the error page error pages built in to ASP.NET/IIS, perhaps offering some advice on why the resource may not exist or providing an option to search the site. For the purposes of this blog post, my custom 404 page is very simple, but you can see some really nice examples here.
404 Page Not Found 404 Page Not Found
I created a new ASP.NET MVC 5 redirect to error 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 inside
:
I've set mode="On" so we can view the custom errors pages locally. Generally you would only want to display these in production so would set mode="RemoteOnly". Now if I navigate to /foo/bar once more I see my custom error page. However, the URL is not /foo/bar as I'd expect. Instead ASP.NET issued a redirect to /404.html?aspxerrorpath=/foo/bar. Also if I check the HTTP status code of the response, it's 200 (
