Nginx can not forward the request protocol correctly to upstream

Question

I have a website in rails 4 beta. It is running on Nginx + Unicorn. I want nginx to forward the request protocol ( \'http\' or \'https\' ) to unicorn so that I can work with

Answer 1

try:

proxy_set_header X-Forwarded-Proto $scheme;

OR

server {
    Listen 80
    ...
}
server {
    Listen 443
    ...
    location @unicorn {
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-Ssl on;
    }
}

Answer 2

You will need to configure two separate server blocks. One for HTTP and one for HTTPS. It will make configuring the two a whole lot easier. Parts that are identical you can include from a separate shared config file.
