This flag specifies that Online Certificate Status of our own certificate must be checked and returned to the peer as OCSP staple when running as a server. When running as a client, it requests OCSP staple. Using this parameter requires LWP::UserAgent and HTTP::Request Perl modules.

Using TLS_OCSPStapling does not require that TSL_OCSPCheck is set, but the same requirements apply when you use only TLS_OCSPStapling. See the requirements list in Section 3.11.32. TLS_OCSPCheck.
