Hello Kyle!
[https://datatracker.ietf.org/doc/html/rfc2616#section-4.4 RFC 2616] is
obsoleted by [https://datatracker.ietf.org/doc/html/rfc7230 RFC 7230]
which in turn is obsoleted by RFC 9110 and RFC 9112, and as far as I read
in [https://datatracker.ietf.org/doc/html/rfc9112#message.body RFC 9112],
both headers could co-exist (but `Content-Length` should be ignored if
`Transfer-Encoding` is sent):
> Early implementations of Transfer-Encoding would occasionally send both
a chunked transfer coding for message framing and an estimated Content-
Length header field for use by progress bars. This is why Transfer-
Encoding is defined as overriding Content-Length, as opposed to them being
mutually incompatible.
But, at the same time, I found an analogous issue for
[https://github.com/django/daphne/issues/371 Daphne], and I see that you
have just commented on the other referenced Daphne issue, so this may be a
valid issue. I will cc/Carlton to confirm before fully triaging.
