If you are SSL on the frontend (server directive) why would you want to proxy between ssl/non-ssl on the upstreams? Can they not be the same? I don't get what you are trying to solve?

Subject: Nginx multiple upstream with different protocols
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_backendhttps://urldefense.proofpoint.com/v2/url?u=http-3A__proxy-5Fbackend&d=DwMFAw&c=WUZzGzAb7_N4DvMsVhUlFrsw4WYzLoMP5bgx2U7ydPE&r=20GRp3QiDlDBgTH4mxQcOIMPCXcNvWGMx5Y0qmfF8VE&m=ggR0dMpbDQRqzdhj1Aoq_FUpo8iYplzYiTPyRlQMs9Y&s=wcDWb0xGOKhBVtan1kM5-AVvxNT0ZMnUT9r-yLbyjAQ&e=;
#proxy_pass https://proxy_backendhttps://urldefense.proofpoint.com/v2/url?u=https-3A__proxy-5Fbackend&d=DwMFAw&c=WUZzGzAb7_N4DvMsVhUlFrsw4WYzLoMP5bgx2U7ydPE&r=20GRp3QiDlDBgTH4mxQcOIMPCXcNvWGMx5Y0qmfF8VE&m=ggR0dMpbDQRqzdhj1Aoq_FUpo8iYplzYiTPyRlQMs9Y&s=ztdy1u_d7Ag0QPBnpk1R-LazdfexcrTnljKLZet4VFA&e=;
}
}
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
