Depends on the message and application. The point here is that there is no reason to confine HTTP to TCP. You obviously only use the UDP transport when you know the network is in a good shape and when loosing a message here and there is not a big deal, and there is several such applications. And DTLS is not by definition unreliable. It may be used alike over unreliable transports such as UDP or over reliable message transports such as SCTP. The reliability of the delivery in DTLS is a property of it's underlying transport, not the DTLS protocol as such. HTTP is a request/response message exchange protocol. At the high level message level it's pretty ignorant about the transport. Regards Henrik
