--doh-cert-status

Same as --cert-status but used for DoH (DNS-over-HTTPS).

Verifies the status of the DoH servers' certificate by using the Certificate Status Request (aka. OCSP stapling) TLS extension.

If this option is enabled and the DoH server sends an invalid (e.g. expired) response, if the response suggests that the server certificate has been revoked, or no response at all is received, the verification fails.

This support is currently only implemented in the OpenSSL and GnuTLS backends.
