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.
