custom-errors

I am using a custom authorize attribute in a ASP.NET MVC 5 application like following: public class CustomAuthorizeAttribute : AuthorizeAttribute { protected override void HandleUnauthorizedRequest(AuthorizationContext context) { if (context.HttpContext.Request.IsAuthenticated) { context.Result = new System.Web.Mvc.HttpStatusCodeResult((int)System.Net.HttpStatusCode.Forbidden); } else { base.HandleUnauthorizedRequest(context); } } } In system.web section of my web.config I mentioned error paths like: <system.web> <customErrors mode="On" defaultRedirect="/Error/Error"> <error statusCode="403"

While this is more of a written language issue than a coding one, it is something that programmers must do in circumstances where copy is not provided by a client or someone else. Any examples of error messages, good or bad, are welcome to make the point. I briefly searched and could not find a dupe thread. Ok, have at it. Thanks, all. Apologise. Say what went wrong. Say how to resolve it. Be polite. The message should be worded so that the application accepts responsibility for the problem. Never blame or criticize the user or make them think it's their fault. Example: "Sorry, the file could

How do I create a custom validator in grails and make it pass a custom string back to the view and an error message?

The page works locally with no errors or warnings. Also if I upload the page as a .html file, I can view it fine remotely. I have seen a lot of other people with this error, but the 'solutions' just say to change the customErrors tag to 'Off', which I have done and does not work, do you know is there an issue with the webserver or what could be the problem here? Here is the error page: Server Error in '/'

I like to give helpful errors / messages, and I also want to do so for my static_assert s. The problem is, that they depend on template parameters. Normally, those parameters will get displayed on way or an other due to the error raised, but they are either obscure or not grouped so they make sense.
