 * A destination for those transports that are multiplex (e.g. HTTP/2).
 * Transports that negotiate the protocol, and therefore do not know in advance
 * whether they are duplex or multiplex, should use this class and when the
 * cardinality is known call {@link #setMaxRequestsPerConnection(int)} with
 * the proper cardinality.
 * If the cardinality is {@code 1}, the behavior of this class is similar
 * to that of {@link DuplexHttpDestination}.
