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 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:
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 matchwe use for custom 404 and other error pages for ASP.NET websites running on IIS 7+. 12 https://tedgustaf.com/blog/2011/custom-404-and-error-pages-for-asp-net-and-static-files/ May 2011 0 Share it: We want custom 404 and other error pages I post this to remind myself how we got this working for both ASP.NET and static http://www.andornot.com/blog/post/Handling-404-errors-with-ASPNET.aspx files, both for remote and local requests on IIS 7 and IIS 7.5.
October 02, 2009 3:21 PM As mentioned at the end of my previous post on handling errors with ASP.NET, handling "404 Not Found" errors are particularly problematic (if you haven't read it yet, please do so). And looking around, the vast majority of information out there on it is not complete, misinformed, or flat-out wrong (but I greatly appreciate all efforts!). And I would argue that this is because ASP.NET implementation of 404 error handling is flat-out-wrong. So with my super hero cape on, here I come to wobbly save the day! The typical ASP.NET way to handle 404 errors is to put something like the following in your Web.config:
