Parent Elements Element Description configuration Specifies the required root element in every configuration file that is used by the common language runtime and the .NET Framework applications. system.web Specifies the root element for the ASP.NET configuration section. customErrors Provides information about custom error messages for an ASP.NET application. It can be defined at any level in the application file hierarchy. Example The following configuration code example specifies the error handling pages to use for an ASP.NET application. The custom errors are only issued for the elements that are handled by ASP.NET. For example, if you refer to a non-existing .htm page, Microsoft Internet Information Services (IIS) issues the standard 404 error. If you refer instead to a non-existing .aspx page, ASP.NET issues the custom 404 error, if you configured the error. Copy

Sure, your users see httperrors web.config example a pretty error page just fine, but your users aren’t always flesh and blood. responsemode= executeurl Search engine crawlers are also your users (in a sense), and they don’t care about the pretty pictures and funny

one-liners on your error pages; they care about the HTTP status codes returned. For example, if a request for a page that was removed consistently returns a 404 status code, a search engine will https://msdn.microsoft.com/en-us/library/s2f4e3e7(v=vs.85).aspx remove it from its index. However, if it doesn’t and instead returns the wrong error code, the search engine may leave the page in its index. This is what happens if your non-existent pages don't return the correct status code! Unfortunately, ASP.NET custom error pages don’t return the correct error codes. Here’s your typical ASP.NET custom error page configuration that goes into the Web.config:
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) http://benfoster.io/blog/aspnet-mvc-custom-error-pages 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 custom error page 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 insideKeep ASP.NET error pages out of search engines Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest In a production environment, users should not be presented the default ASP.NET error pages. Instead they should be offered clean, understandable error pages giving them a sensible explanation of the error, along with suggestions to continue their journey on the website. Besides usability concerns, it's also an important security practice to not leak details about application details to those who might tinker with your application! In ASP.NET, thecustomErrors configuration element is used to handle error situations. However, the behaviour of the custom errors is somewhat counterintuitive, as you might end up with your error pages indexed by search engines. How customErrors work First a quick example of how a customError section might look like in a web.config file (this belongs under system.web):
