Minimal valid tls session?

[Christophe Lohr <christophe.lohr@xxxxxxxxxxx>]

    Hello,
      what could be the minimal, but valid, tls session?
    (with the minimum number of bytes on the wires, but without causing
    an error on the client side)
    
    I mean, just similar to the plain old Discard service, but for tls
    ;-)
    
    Could this be at the step of the Server Hello
    Response, or later?
    
    Well, this is probably stupid, but I'm curious...
    
    Regards
    Christophe
