The connection:close header is used to say that once the request is
done, and to avoid attempting to reuse it as keep-alive for a follow-up
request. There's nothing bad about it, and it is not relevant to the
fact you are streaming. The streaming is part of chunked encoding (which
has no content length known ahead of time, and is self-delimiting),
related to the body, not the connection.

That's because you need to use `--raw` in curl to avoid seeing the
content body already decoded. `-v` will decode chunked content and
display it as it comes. You can also try a tcpdump to see the raw data.

Don't. Nothing you specified there is actually a problem unless they
advertise keep-alive connections forever.
