But you're aware that what you're asking for is a direct violation of
basic HTTP messaging rules stating that no agent may depend on chunk
delivery due to anything along the chain possibly having to buffer some
of the data for analysis or transformation. I just found it now, it's
RFC9110#7.6:
https://www.rfc-editor.org/rfc/rfc9110
An HTTP message can be parsed as a stream for incremental processing or
forwarding downstream. However, senders and recipients cannot rely on
incremental delivery of partial messages, since some implementations will
buffer or delay message forwarding for the sake of network efficiency,
security checks, or content transformations.
Note: this text was already in RFC7230 9 years ago so it's not something
new.
It's interesting to note that this would also mean that "Server-sent events"
https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events
that are an "official" feature of web browsers / the JavaScript API
would be in violation of the HTTP semantics.
