SSL: client certificate validation with OCSP (ticket #1534). OCSP validation for client certificates is enabled by the "ssl_ocsp" directive. OCSP responder can be optionally specified by "ssl_ocsp_responder". When session is reused, peer chain is not available for validation. If the verified chain contains certificates from the peer chain not available at the server, validation will fail.
