Stream ssl_preread: $ssl_preread_protocol variable. The variable keeps the latest SSL protocol version supported by the client. The variable has the same format as $ssl_protocol. The version is read from the client_version field of ClientHello. If the supported_versions extension is present in the ClientHello, then the version is set to TLSv1.3.
