Net Custom Error Pages
Contents |
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 asp.net mvc custom error page just configure our custom error pages in one place and it would just work, no matter asp.net custom error page how/where the error was raised. Something like:
Custom Error Page Template
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
I created a new ASP.NET MVC 5 application using the standard template in Visual Studio. If I run asp.net mvc error handling 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.

The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectE

For this example we will be using IIS 7.5 which shipped with Windows Server 2008 R2. If we configure .NET Error Pages at the site level, ASP.NET stores the settings in the site's web.config file. Since these settings are stored in the web.config file they are portable and can be easily moved to another server with the site's content. How to setup Custom Error Pages in IIS 7.5 Open Internet Information Services (IIS) Manager. Select your website. Note: This could also be set at the server level and applied to all sites on the server. DoubleClick on the ".NET Error Pages" icon. The .NET Error Pages features view will be displayed. Click the "Edit Feature Settings" link to enable this feature. The "Edit Error Page Settings" dialog box will appear. In order to change the default mode, we must also specify a "Default Page". This page will be used for all status codes that are not otherwise defined. In our example we are using a generic custom error page to trap all other errors. Once you enter the absolute URL for the default error page click OK. Note: It may be a good idea to use a static HTML page here just in case ASP.NET is not functioning properly. By default server errors are shown when logged on locally to the IIS server and custom errors will only be used from remote sessions. We will want to change this to "On" if we are logged on locally to the IIS server. Otherwise, it will display detailed server errors, and not our custom error pages. Next we will explicitly define the 404 Error code. To get the browser to throw a 404 error, we pointed it to a file on the test site that does not exist. As you can see in the following image the friendly HTTP 404 error page was shown in IE9. A friendly HTTP 404 Error in IE9: On the .NET Error Pages Actions menu click the Add link. The "Add Custom Error Page" dialog will appear. This is where we define individual error pages per status code. For our example we will add a custom page for the HTTP 404 Error. Now that we have turned on the feature and added a custom page for the 404 status code we can verify it is working. To verify visit a page that does not exist. In our example we will use http://mysite.com/deletedfile.aspx. You can see in the following im
