Question

Best way to abort/cancel action from ActionFilter

I\'ve got this ActionFilter, and it\'s suppose to end the connection immediately and return a 401 Unau

Answer 1

You probably want to make it an AuthorizeAttribute. That will set the result to be an UnAuthorizedResult automatically, plus it has the benefit of being run before any other filters. Alternatively you can set the Result to be a new HttpUnauthorizedResult

public class SignInRequiredAttribute : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        return !Acme.Web.CurrentUser != null;
    }
}
