18, 200711 0 0 0 Yesterday, I came up with https://blogs.msdn.microsoft.com/rahulso/2007/01/18/customize-errors-which-are-not-captured-by-customerrors-in-asp-net-2-0/ an interesting issue where a customer wanted to customize a 500 error message ("Internal Server Error"). Interestingly, customErrorsDID NOTseem to work for https://www.safaribooksonline.com/library/view/learning-aspnet-20/9780596513979/ch10s12.html StatusCode 500! We just wanted to verify if it works for 404,and it did… Ideally, this should have worked… but may be it didn't because some errors are not customizable… http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/80cb8d8d-8fd8-4af5-bb3b-4d11fff3ab9c.mspx?mfr=true Let us reproduce the error in just a few steps and then we will fix it by creating an HttpModule to handle our scenario. 1. error page in Create a new ASP.NET web service using VB.NET (or C#)2. Set Service.asmx as start page. 3. Browse to http://localhost/CustomError/Service.asmx?WSDL=> This should work4. Now, browse to http://localhost/CustomError/Service.asmx?WSDL=12=> This should fail with an error code 500 and description "Internal Server Error" So, now since we are able to repro this error pretty easily, we will start the next step of fixing this and ensure that whenever this happens, we are redirected appropriately to the ErrorPage.aspx. 1. Start by creating a custom page called ErrorPage.aspx under your project folder directly.2. Under the App_Code folder create a VB class file called ErrorModule.vb and paste the following code… Imports Microsoft.VisualBasicPublic Class ErrorModule Implements IHttpModule Public Sub Dispose() Implements System.Web.IHttpModule.Dispose ‘Hmmm… let it be! End Sub Public Sub Init(ByVal context As System.Web.HttpApplication) Implements System.Web.IHttpModule.Init AddHandler context.EndRequest, AddressOf ErrorRedirector End
