I would like to configure CDP = https://crl.test.com/test.crl
But the warning message says https protocol is not supported.
How to force CDP to https?
If impossible, could you tell reason that it's impossible?

Hi,
Never use HTTPS protocol for crt or crl file retrieval, because Crypto API will permanently fails to fetch this URL because the client need to validate the certificate used for HTTPS protocol and to validate it the client needs to access to crl

I'm pretty sure you don't want that. You MUST NOT serve CDP/AIA/OCSP URLs over HTTPS, use plain HTTP only. Otherwise you will enter into a endless loop while accessing CDP, because SSL certificate must be validated. Many cryptographic libraries will fail URL fetching if it is served over SSL. Leave HTTP as is.
