nginx/1.26.1 as a reverse proxy strips the Content-Length field from response, no matter what I do

[Tobias Damisch]

I am awfully sorry for spamming this list.

I just found out nextcloud starts sending the file several times,
sometimes containing "Content-Length" and sometimes not. The one time it
actually serves the full download, this is the header:

------------------------------------------------------------------------
HTTP/1.1 200 OK^M
Content-Disposition: attachment;
filename*=UTF-8''debian-12.6.0-amd64-netinst.iso;
filename="debian-12.6.0-amd64-netinst.iso"^M
Content-Security-Policy: default-src 'none';^M
Content-Type: application/octet-stream^M

X-Frame-Options: SAMEORIGIN^M
X-Permitted-Cross-Domain-Policies: none^M
X-Request-Id: <censored>^M
X-Robots-Tag: noindex, nofollow^M
X-Xss-Protection: 1; mode=block^M

-------------------------------------------------------------------------

So I am back to the problem being in nextcloud aio /and not nginx/.

As far as I can see nginx serves Content-Length correctly /if it gets it
served itself/ *sigh*

Sorry again!

Tobias
