seems like a request could be pulled from a queue with HTTPS easily enough. and if I am misunderstanding what you're saying, I don't understand why a purely request-driven path is so vital; it's just a way to me ve data around.

seems like the queue could accept the request, keep the https connection open, wait for a response from whatever server accepts the request, and pass the response to the client upon receipt just fine.

I dunno. web stuff is poorly done imo. poorly designed.
