Question

User1697794668 posted

Hi there,

I am using NTLM basic authentication.
When accessing an invalid page such it will got to 401, how do I redirect it to a custom error page.'

The same question when you do for a bad request 400.
As far as I know, it is not possible to redirect the request to a custom error page.
Is it possible to append the request to a load balancer.

Hi,

401 should tell the browser authentication is required. IMO you dont't need a custom page for this one.

You could try https://www.tutorialsteacher.com/articles/display-custom-error-page-with-error-code-in-aspnet-mvc or you could customize the IIS default error pages found at %SystemRoot%\Help\IisHelp\Common

Hi alvinoo,

According to your description, if you want to redirect the url to a custom error page when the user request is not authorized, have you tried a similar solution in this case?

ASP.NET WindowsAuthentication custom 401 Unauthorized error page
