#395: Session resumption


Comment (by Hannes.Tschofenig@gmx.net):

 In http://www.ietf.org/mail-archive/web/core/current/msg06909.html Hannes
 assumed that the question was about TLS session resumption. Instead the
 question focused on TCP, as Klaus clarified in http://www.ietf.org/mail-
 archive/web/core/current/msg06948.html

 -------------------

 To clarify, the question is about sessions at the CoAP level, not at
 the DTLS/TLS level.

 Should it be possible to send a CoAP request, close the TCP
 connection, reconnect and receive the response?

 -------------

 Both Klaus and Carsten subsequently agree that there is no expectation
 that a re-connect from the client would allow it to retrieve (buffered)
 data. Instead the connection lifetime is bound to the TCP connection.
