Hi,
i'm trying to setup two Nginx upstreams (one with HTTP and one with HTTPS) and
the proxy_pass module should decide which of the upstreams is serving "valid"
content.
The config should look like this:
upstream proxy_backend {
server xxx.xx.188.53;
server xxx.xx.188.53:443;
}
server {
listen 443 ssl;
...
location / {
proxy_pass http://proxy_backend;
#proxy_pass https://proxy_backend;
}
}
The Problem is that i don't know if the upstream is serving the content via
http or https. Is there any possibility to tell nginx to change the protocol
from the proxy_pass directive? Because if i set proxy_pass to https, i get an
error (502 / 400) if the upstream website is running on http and vice versa.
So i'm searching for a way to let Nginx decide if he should proxy_pass via http
or https. Can anybody help me with that configuration?
Thanks
