I have a HttpModule that redirects certain URL:s in an ASP.NET WebForms application. It works on my machine with the ASP.NET Development Server. But when I upload it to our Win2k8 server with IIS7, it doesn't seem to react at all. I've put the <add name="Test.Web" type="Test.Web.Core.HttpModules.RedirectOldUrls, Test.Web" /> in the syste...
