You're thinking of this RFC5077 or its predecessor RFC4507, which only became implemented in OpenSSL 0.9.9 (http://rt.openssl.org/Ticket/Display.html?id=1574). The usual way to achieve session resumption before that was to keep around (cache) symmetric key data for a predefined period of time. Trouble is that many unixoid OS distributions still ship with a system OpenSSL version < 0.9.9.
