OCSP stapling) TLS extension. 21 22If this option is enabled and the DoH server sends an invalid (e.g. expired) 23response, if the response suggests that the server certificate has been 24revoked, or no response at all is received, the verification fails. 25 26This support is currently only implemented in the OpenSSL and GnuTLS backends. 27
