Hello,
i'm running a nginx (version: nginx/1.13.1) with two vhosts with exact the same
configuration. The only difference is the upstream section: each vhosts points
to a different upstream server / ip.
My configuration looks like this:
###
...
location / {
proxy_pass http://IP_ADDRESS;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $proxy_protocol_addr;
proxy_set_header X-Forwarded-For $proxy_protocol_addr;
}
...
###
vhost_1 works without any problem and i can see both proxy_headers in the
tcpdump and in my upstream-apache access-logs.
vhost_2 doesn't show me any x-forwarded headers, whether in the upstream-apache
nor in the tcpdump (which is running locally on my nignx host). So it looks
like when apache doesn't attach the upstream_headers to the HTTP request.
Additionally i can see via tcpdump that HTTP protocol (get request) to vhost_2
(borken) is 1.0 and to vhost_1 (working) is 1.1; However, both responses are
1.1 so both upstream-apaches are capable of HTTP 1.1.
Does somebody know why my nginx is sending its HTTP request to vhost_2 via HTTP
1.0 and not 1.1? And if, could that be that HTTP 1.0 is not working with
proxy_set_header?
Thats the only difference im seeing in my setup / tcpdump ... could there be
any other difference why nginx is not attaching the upstream headers to my
vhost_2?
Thanks
Greets
