Custom 403;4 error

[GabeC]

We are using Windows 2003, IIS 6.0

We would like to use a custom 403;4 error page that is a .asp page.

If someone types in

http://www.mydomain.com/default.asp

we want the 403;4 page to redirect to

https://whatever_they_entered

We can use the .asp extension for the 404 custom error but it doesn't work with the 403;4. We have tried the type as File and URL.

Does anyone know how to make .asp pages work with the 403;4 customer error page?

Thanks for your help and suggestions

Thanks,

Gabe
