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 nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name extensions to ASP.NET.

So I am thinking changing the code below to write text log instead email, then on sql error, write text log. void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs string testEnvironment = ConfigurationSettings.AppSettings["isTestEnvironment"]; if (testEnvironment == "0") { Exception ex = Server.GetLastError(); if (ex is HttpException && ex.InnerException is ViewStateException) { Response.Redirect(Request.Url.AbsoluteUri) return } StringBuilder theBody = new StringBuilder(); theBody.Append("URL: " + Request.Url + "\n"); theBody.Append("Referer: " + Request.ServerVariables["HTTP_REFERER"] + "\n"); theBody.Append("IP: " + Request.ServerVariables["REMOTE_HOST"] + "\n"); theBody.Append("Error Message: " + ex.ToString() + "\n"); if (User.Identity.IsAuthenticated) theBody.Append("User: " + User.Identity.Name + "\n"); else theBody.Append("User is not logged in." + "\n"); theBody.Append("Form Values: " + "\n"); foreach (string s in Request.Form.AllKeys) { if (s != "__VIEWSTATE") theBody.Append(s + ":" + Request.Form[s] + "\n"); } theBody.Append("Session Values: " + "\n"); foreach (string s in Session.Keys) theBody.Append(s + ":" + Session[s] + "\n"); System.Net.Mail.MailMessage email = new System.Net.Mail.MailMessage(); email.IsBodyHtml = false; email.From = new System.Net.Mail.MailAddress("errors@karpach.com", "ErrorManager"); email.To.Add(new System.Net.Mail.MailAddress("errornotification@karpach.c
