for a web to DNS proxy to decide to send a reply back, it would need to
consider it complete?
Or are you proposing that the http server would start streaming back the
payload as it received the (possibly out of order) replies?
I was thinking that the proxy would get all the queries from the DNS
request, deal with them however it wants, maybe stuff them to a nearby DNS
cache with TCP if it pipelines properly, or split them up into separate
requests if it doesn't, then collect the responses and send them back when
it has them, which I guess would constitute streaming. RFC 7766 says that
out-of-order is fine.
I suppose with http/2 we get two-way streaming more or less for free.
