TLS 1.3 supports client-side OCSP stapling when a server places the status_request in a CertificateRequest message it sends to the client.  This feature would implement the client-side ability to staple OCSP responses and send them to a server.  It also implements the server-side support for asserting the status_request extension in TLS 1.3 CertificateRequest messages and the proper evaluation of stapled OCSP responses when provided by the client.
