ocspCustomCname
By default, Amazon Web Services Private CA injects an Amazon Web Services domain into certificates being validated by the Online Certificate Status Protocol (OCSP). A customer can alternatively use this object to define a CNAME specifying a customized OCSP domain.
The content of a Canonical Name (CNAME) record must conform to RFC2396 restrictions on the use of special characters in URIs. Additionally, the value of the CNAME must not include a protocol prefix such as "http://" or "https://".
