ssl_c_version <integer>
Returns true when the incoming connection was made over an SSL/TLS transport
layer, and the version of the certificate presented by the client matches
the value.
ssl_f_serial <hexa>
Returns true when the incoming connection was made over an SSL/TLS transport
layer, and the serial of the certificate presented by the frontend matches
the value written in hexa.
ssl_f_version <integer>
Returns true when the incoming connection was made over an SSL/TLS transport
layer, and the version of the certificate presented by the frontend matches
the value.
ssl_fc
Returns true when the front connection was made via an SSL/TLS transport
layer and is locally deciphered. This means it has matched a socket declared

ssl_c_version
Returns the version of the certificate presented by the client

ssl_f_serial Returns the serial of the certificate presented by the frontend
when the incoming connection was made over an SSL/TLS transport

ssl_f_version
Returns the version of the certificate presented by the frontend

ssl_fc This checks the transport layer used on the front connection,
and returns 1 if it was made via an SSL/TLS transport layer,
otherwise zero.
