The customErrors element can be defined at any level in the application file hierarchy. Copy Attributes and Elements The following sections describe attributes, child elements, and parent elements. Attributes Attribute Description defaultRedirect Optional attribute. Specifies the default URL to direct a browser to, if an error occurs. When this attribute is not specified, a generic error is displayed instead. The URL can be absolute (for example, www.contoso.com/ErrorPage.htm) or relative. A relative URL, such as /ErrorPage.htm, is relative to the Web.config file that specified the URL for this attribute, not to the Web page in which the error occurred. A URL starting
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 customerrors mode= off I expect such is the case with some other frameworks/servers) we would customerrors vs httperrors just configure our custom error pages in one place and it would just work, no matter how/where the error was customerrors mode= on not working raised. Something like: Custom 404 error pages When a resource does not exist (either static or dynamic) we should return a https://msdn.microsoft.com/en-us/library/h0hfz6fc(v=vs.85).aspx 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 http://benfoster.io/blog/aspnet-mvc-custom-error-pages 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
:
I've set mode="On" so we can view the custom errors pages locally. Generally you

(that works) If a user does something, that throws an error, he should see the Stacktrace and the real Errorpage. This is my current Web.config: with this configuration, customerrors mode= on a 404 will be redirected to the right site, but a HTTP 500 will be shown as following: Server Error in '/' Application Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web [.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". [...] But in this case i want to show the stacktrace. How can i do this?

When developing I use windows 7 and VS 2010 with IIS 7.5 as well. I've setup my web.config as such: And my Error404.aspx page has this in its code-behind: protected void Page_Load(object sender, EventArgs e) { Response.StatusCode = 404; } On my developer machine this works fine, I see my pretty errorpage in the browser, and using Fiddler I can confirm I only receive the 404 HTTP status. Now when I publish it to my server, it's a different story. Here I'll see the IIS' own 404 page ("C:\inetpub\custerr\en-US\404.htm") If I remove the Response.StatusCode in my code-behind, I get the errorpage fine on the server, albeit with a 200 HTTP status. What am I overlooking since this doesn't work ? asp.net c#-4.0 iis-7.5 share|improve this question asked Mar 10 '11 at 8:56 Steffen 6,10833257 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Does this article by Rick Strahl help?
