For example, you might want to customize each of the error message pages for your Web site to have the same look asp net ascx and feel as the rest of your site. The element contains a collection of elements, each of which defines an error message that IIS uses to respond to specific HTTP errors. You can add custom error messages to IIS by adding an element to the element in the Web.config file for your site, application, or URL. Each element uses asp net html the responseMode attribute to specify whether IIS serves static content, dynamic content, or redirects to a separate URL in response to an error. You can use the element to remove a specific error message from the collection of error messages your site or application inherits from a higher level in the IIS configuration hierarchy. Also, you can use the element to remove all HTTP error messages from the collection of HTTP error messages that your site or application inherits. The element also contains attributes that configure IIS 7 to process requests that cause errors. The existingResponse attribute defines what IIS 7 does to an existing response when the server returns an HTTP error status code. The defaultPath attribute defines the path to a customer error page if you choose specify File for the responseMode attribute in an element. The detailedMoreInformationLink attribute specifies a link to more information about a particular error. The element also can contain an errorMode attribute that you can use to control the level of detail that IIS returns to a browser when an HTTP error occurs. You can set the errorM

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 Pu
we use for custom 404 and other error pages for ASP.NET websites running on IIS 7+. 12 May 2011 0 Share it: We want custom 404 and other https://tedgustaf.com/blog/2011/custom-404-and-error-pages-for-asp-net-and-static-files/ error pages I post this to remind myself how we got this working http://benfoster.io/blog/aspnet-mvc-custom-error-pages for both ASP.NET and static files, both for remote and local requests on IIS 7 and IIS 7.5. over in web.config is a construct for specifying custom error pages for requests handled by ASP.NET. In other words, static files such as HTML files or directory (“friendly”) URLs are not handled. asp net configures error pages in IIS itself, outside the web application. This handles all requests, whether they’re in fact handled by ASP.NET or IIS natively. We ignore customErrors altogether and only use httpErrors. Displaying a static HTML file This is useful for error codes such as 500 where the ASP.NET web application in itself may suffer problems: Displaying an ASP.NET page asp net http This displays an ASP.NET page when a 404 error occurs, without rewriting the URL (the visitor will still see the requested URL in the address bar): Note that we skip the element and simply remove the standard 404 handling (in order to avoid an exception caused by duplicate elements for the 404 status code). Redirecting to another URL ExecuteURL can only be used to execute an ASP.NET file within the same application. If we want to redirect to another application, or possibly an entirely different external URL, we use the Rewrite response mode with an absolute URL: Make sure HTTP errors is enabled in IIS For this to work you have to make sure the HTTP Errors feature is installed for IIS, otherwise you’ll just get an empty 404 response: More on httpErrors You can find more information on IIS.net or on MSDN.

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: 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 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 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
