}

How to do it?

Answer 1

The answer from nemesv is correct, but I just wanted to add an example using the ViewRenderer instead of the GenericFileResponse.

public class MyStatusHandler : IStatusCodeHandler
{
    private IViewRenderer viewRenderer;

    public MyStatusHandler(IViewRenderer viewRenderer)
    {
        this.viewRenderer = viewRenderer;
    }

    public bool HandlesStatusCode(HttpStatusCode statusCode,
                                  NancyContext context)
    {
        return statusCode == HttpStatusCode.NotFound;
    }

    public void Handle(HttpStatusCode statusCode, NancyContext context)
    {
        var response = viewRenderer.RenderView(context, "/status/404");
        response.StatusCode = statusCode;
        context.Response = response;
    }
}
