django through lighttpd + mod_proxy + gunicorn: X-Sendfile returns empty responses
I'm using Django behind Gunicorn and lighttpd. As of Gunicorn documentation, I configured Lighttpd to act as reverse proxy towards Gunicorn:
$SERVER["socket"] == "0.0.0.0:80" {
server.document-root = "/home/user/app"
server.errorlog = "/var/log/lighttpd/app-error.log"
accesslog.filename = "/var/log/lighttpd/app-access.log"
$HTTP["url"] !~ "^/static/" {
proxy.server = (
"" => (
(
"host" => "127.0.0.1",
"port" => 8888,
"allow-x-send-file" => "enable"
)
)
)
}
}
So far so good, everything works and even static files are served correctly.
Now I'm trying to use the header X-Sendfile. In my Django code:
response['Content-Type'] = 'application/force-download'
response['Content-Disposition'] = f'attachment; filename={smart_str(send_name)}'
response['X-Sendfile'] = '/tmp/big-file.txt'
/tmp/big-file.txt exists and is accessible by the Lighttpd process.
Every time I try to serve a file this way, the browser gets an empty response; no payload and Content-Length: 0.
I find nowhere any error from Lighttpd (I think the Django + Gunicorn part is fine) about what's going wrong.
What can I do? Where's my mistake?

Check that your script did not already send response headers before you tried to set X-Sendfile.
You can use strace on the lighttpd process to see what is received from the backend, as well as to see if lighttpd is trying to open '/tmp/big-file.txt'
