I wonder though, doesn't SSE technically violate a lot of HTTP's assumptions? From the point of view of a HTTP middlebox, a SSE response would basically be a single endless entity, transmitted at a very low bandwidth. I'm no expert at real-world deployment of SSE, but that they sounds to me like it could break a lot of proxies that don't have special handling for SSE. (Or at least cause unnecessary resource consumption for those proxies)

Also I wonder why there are not more websocket-based APIs. WS has the same widespread support and ready-made debug tools as HTTP and seemed to be designed exactly for push or non request/response use cases. So, out of couriosity, why would SSE be prepared over WS?

It looks like you accidentally duplicated your comment when you changed "prepared" to "preferred".

I'm sorry. That was my attempt at "editing" the post after the noprocrast mode kicked in - before an unintelligible post would sit there for ~3 hours...

If any mods could delete this, I'd be grateful.
