You can also redirect to the controller's action method when an exception occurred. The following setting will redirect to the Index action method of the ErrorController in MVC application.
Depending on your type of application, there are potentially multiple ways to do this. If your application has a Global.asax file, you can subscribe to unhandled exceptions as shown below and then log them with log4net, NLog, Serilog, or some other logging framework.
Part of that includes collecting all application exceptions. Retrace can collect unhandled exceptions, exception s explicitly logged to it, or every single exception ever is thrown ( first chance exceptions ). To make the most of your application errors, you should use an error monitoring service, like Retrace.
In general, watch out for config transforms (e.g. Web.Debug.config which could change that value), and watch out for duplicate definitions of that section/property in the file (clearly wasn't the issue in this case)
This seems to be a default setting in .NET 4.0 - I had the same trouble figuring it out. Agree that it's a good setting to use in a production environment, but seeing the REAL error is very important when debugging.
I also had this problem, but when using Apache and mod_mono. For anyone else in that situation, you need to restart Apache after changing web.config to force the new version to be read.
So try not to use notepad to inspect web.config on a remote server.
Actually, what I figured out while hosting my web app is the the code you developed on your local Machine is of higher version than the hosting company offers you. If you have admin privileges you may be able to change the Microsoft ASP.NET version support under web hosting setting
Set the redirectMode attribute to ResponseRewrite. This will keep the original URL but still display a custom page. Note that ResponseRewrite is only applicable for .aspx, or .html files, but not for action methods. If you want to set action methods for different status codes, keep the ResponseRedirect value.
RemoteOnly: Specifies that custom errors are shown only to remote clients, and ASP.NET errors are shown to the localhost. This is the default.
Use the defaultRedirect to specify where an http request should be redirect by default if an error occurs. You can specify the name of a webform, an HTML, or an action method. This will redirect to this page on any error code, not just 500.
ASP.NET MVC application displays the flowing screen (Yellow Screen of Death) by default when an exception occurs that shows the error information if you are running it from the localhost.
Create 500.html, 404.html, and 400.html files at the root of the application. The above settings will keep the original URL without a query string while showing the inner content of an HTML page with the response status code 200 OK.
You can also set different action methods or pages for different error codes using child <error> elements. The following sets different action methods for different error codes.
The <customErrors> configuration will always return a response with 200 status code. This is not a good SEO practice for websites. Learn How to display a custom error page and return error code using httpErrors in ASP.NET MVC .
