Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. 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 DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a

Here's how it looks: Global.asax: protected void Application_Error(object sender, EventArgs e) { Exception ex = Server.GetLastError(); string path = "N/A"; if (sender is HttpApplication) path = ((HttpApplication) sender).Request.Url.PathAndQuery; string args = string.Format("Path: {0}", path); // Custom code that generates an HTML-formatted exception dump string message = Email.GenerateExceptionMessage(ex, args); // Custom code that sends an email to the dev team. Email.SendUnexpectedErrorMessage("Some App", message); } One "minor" problem, though - when I intentionally have a part of the code throw an exception in order to test this mechanism... public static void GetMuffinsByTopping(string topping) { throw new Exception("Test Exception!", new Exception("Test Inner Exception!!!")); // Actual repository code is unreachable while this test code is there } The front-end JavaScript is immediately intercepting an HTTP 500 request, but the global.asax.cs code noted above is not being reached (I set a breakpoint on the first executing line of the method.) Question: In what way can I get the "old" Application_Error handler to dispatch error emails, so that our team's developers can more easily debug our application? c# asp.net-web-api error-reporting share|improve this question asked Feb 27 '15

I don't want anything pertaining to custom error in the web.config because my plan is to add code to the global.asax file to log the exceptions. Is there a way to handle custom error with just the global.asax file? Thanks. c# asp.net share|improve this question edited Aug 15 '14 at 6:21 asked Aug 15 '14 at 5:48 frenchie 14.3k64185349 Are you using Cassini, or IISExpress? Which version of .NET? –Tieson T.

As we discussed in the Core Differences Between IIS and the ASP.NET Development Server tutorial , the web server may handle certain requests itself. By default, the IIS web server processes requests for static content like images and HTML files without invoking the ASP.NET engine. Consequently, if the user requests a non-existent image file they will get back IIS's default 404 error message rather than ASP.NET's configured error page. I've emphasized the first line. I tested this out in the default
