will be true, when verify failed but tls_try_verify_hosts allowed the
connection (under OpenSSL)
$tls_{in,out}_cipher will have values different to the original (under GnuTLS)
- $tls_{in,out}_ocsp will be "not requested" or "no response"
+ $tls_{in,out}_ocsp will be "not requested" or "no response", and
+ hosts_require_ocsp will fail
