content-length header missing when using httpx, present when using curl

[mjuopperi]

Hello,

httpx.head("https://www.fuzzwork.co.uk/dump/postgres-schema-latest.dmp.bz2").headers.get("content-length")

returns None and looking at the headers it is not there.

If I do the same request with curl in terminal, I can see that the "content-length" header is there. What might be up?

curl -I https://www.fuzzwork.co.uk/dump/postgres-schema-latest.dmp.bz2
HTTP/2 200
...
content-length: 92616046
...

Turns out I have to set headers={"Accept-Encoding": "identity"} on the request or the server will not send that header.
