copied!<p>I have a C# solution, I hope it helps. I plagiarized some of this code, though for the life of me, I cannot find where I got it from. If anyone know, please let me know so I can add it to my comments. </p> <p>This solution does not use reflection, but it looks at all the application errors (exceptions) and checks to see if it's a 404 error. If it is, then it just routes the current request to a different controller. Though I am not an expert in any way, I think this solution might be faster than reflection. Anyway, here's the solution and it goes into your Global.asax.cs,</p> <pre><code> protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); // A good location for any error logging, otherwise, do it inside of the error controller. Response.Clear(); HttpException httpException = exception as HttpException; RouteData routeData = new RouteData(); routeData.Values.Add("controller", "YourErrorController"); if (httpException != null) { if (httpException.GetHttpCode() == 404) { routeData.Values.Add("action", "YourErrorAction"); // We can pass the exception to the Action as well, something like // routeData.Values.Add("error", exception); // Clear the error, otherwise, we will always get the default error page. Server.ClearError(); // Call the controller with the route IController errorController = new ApplicationName.Controllers.YourErrorController(); errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData)); } } } </code></pre> <p>So the controller would be,</p> <pre><code>public class YourErrorController : Controller { public ActionResult YourErrorAction() { return View(); } } </code></pre>
