getSession

Returns the TLS session data or undefined if no session was negotiated. On the client, the data can be provided to the session option of {@link connect} to resume the connection. On the server, it may be useful for debugging.

See Session Resumption for more information.

Note: getSession() works only for TLSv1.2 and below. For TLSv1.3, applications must use the 'session' event (it also works for TLSv1.2 and below).
