Submitted, because I just found out that even after 28 years, the definition of "upstream" and "downstream" is still heavily contested.

- dilyevsky 2mo agoThe posters interpretation of why Envoy is using downstream on listener side and upstream on backend side is wrong. There's a formal definition in RFC 2616: upstream/downstream Upstream and downstream describe the flow of a message: all messages flow from upstream to downstream. Now HTTP is obviously bi-directional but since for most reverse proxy usecases responses far outweigh the requests upstream means "the backend"
