Get security protocol being used for a request
$Web_Protocol returns an indicator of the network security protocol, if any, being used for a connection. SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are the protocols supported by Janus. The SSLPROT parameter of the JANUS DEFINE command for this server stipulates the specific protocols available for this port. The server and its clients negotiate the security protocol that their connection will use.
%rc = $Web_Protocol
$Web_Protocol takes no arguments and returns a status code.
