I would simply state that there is no guaranteed delivery status when
HTTP/UDP is used. Messages MAY be silently lost when using such
transport and it's up to to the application to handle it gracefully. How
is outside of the specification. There is also other very noticeable
limitations of HTTP/UDP such as maximum message size which is fairly
small. I.e. 64KB on a good day.

If reliable datagram transport is desired then use HTTP/SCTP. It's a
very real alternative in the environments and for the applications where
HTTP/UPD is interesting and provide much the same properties in
unordered (but well defined) delivery of interleaved messages and other
nice properties.

Henrik
