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 mvc 4 custom error page IIS. Ideally (and I expect such is the case with some other frameworks/servers)

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 mvc redirect to error page 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 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 insidehere for a quick overview of the site Help Center Detailed answers to any questions you

Donate Log In ASP.NET MVC5 MVC 5 How To Show Custom Error Pages MVC 5 How To Show Custom Error Pages posted on 11/29/2014 8:13 AM by Eric Butler Tweet While working on Neptune http://www.neptunecentury.com/blogs/asp-net/mvc5/mvc-5-how-to-show-custom-error-pages Century's site redesign, I stumbled upon some issues trying to show custom error pages http://tech.trailmax.info/2013/08/error-handling-in-mvc-and-nice-error-pages/ for 404 and 500 errors. The 500 error is relatively easy to deal with, but 404 was a bit trickier... that is until I realized how to do it with MVC and IIS 8+.The first thing I tried was the ye old customErrors section in System.Web. It did what is was supposed to error page do, that is redirect the user to a friendly 404 error page, but the problem with that approach was that the response code was set to a 302 redirect. That is not a very good solution for SEO optimization. We want the page/url we request to be delivered as a 404 response, not a redirect. Here is an example of what I mean:As you can see in the custom error page image above, the customErrors section causes a 302 redirect. The actual page Error/NotFound contains the 404. This is not what we want! First off, we want the url in the browser to stay the same, but in this case, it changes to Error/NotFound?aspxerrorPath=/Home/FooBar. Ewwwww.In order for us to get a proper status code returned to the browser, and keep our original URL, we need to add a section to the web.config. I also commented outthe customErrors section.When adding this section to your site, keep in mind that if you want to show custom errors while you are developing, you need to set errorMode="Custom". This will allow you to test your error page. Set it to DetailedLocalOnly when you want to see the detailed errors on your development machine.Now, in our ErrorController, we define our actions:Make sure to set the Respone.StatusCode to 404 or the browser will get a 200 (success).One other thing to note; when I added the above to my web.config. At first it didn't work. I had to add the existingResponse="Replace" attribute. This replaces the default 404 / 500 response with your custom content.So, what does it look like now?And a quick check of the developer tools (F
30, 2013 by trailmax | 3 Replies It is vital for your application security not to show any internals when error happen. And you should be able to replace all internal error messages to nice user-friendly pages. It is a just nice for users - they are not getting splashes of oil, when engine is exploded, also another measure to improve site security. There are lot of articles about error handling in ASP.Net MVC, but most of them do not cover the whole range. There is a very good resource on this, and I do recommend reading and understanding that first. With error handling there are a lot of edge cases, and for every single one of them you need to provide a solution, otherwise your error messages will talk too loud about your implementation and that can lead to security vulnerability. Upd 18/03/2016 There are a ton of similar articles on this topic. Here are some nice ones: Ben Foster - probably this one is the most comprehensive and worth reading first. Mahesh Sabnis Milevis Here is the list of edge cases I came up with: Exception thrown in controller Controller or controller action is not found Page not found, but outside of the MVC pipeline Exception in IIS pipeline Cases when IIS can't handle the request all together. Exception thrown in controller. When exceptions are thrown in your code, most of the time they will be thrown in MVC pipeline and handled by MVC error handling mechanisms. First of all you need enable CustomErrors in web.config:
