I'm using Nginx as reverse proxy with SSL termination. The J2EE application that is behind it sometimes uses host information to create URLs for popup windows. Right now it inserts name of my upstream into URL and popup windows are not launched (obviously). I understand that i have to fill 'Host' header with appropriate value. So I tried to use
proxy_set_header Host $host;
inside my 'location' block. It works perfectly when I'm connecting over http. By when I'm connection over https it doesn't work (even more - all pages are not available).
My configuration:
upstream BE {
ip_hash;
server ... max_fails=1 fail_timeout=300s;
server ... max_fails=1 fail_timeout=300s;
}

server {
listen 443 ssl;
server_name localhost;

location / {
proxy_pass http://BE;
# proxy_redirect off;

#proxy_set_header X-Forwarded-Proto https;
#proxy_set_header X-Real-IP $remote_addr;
#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# proxy_set_header Host $host;
}

I found this post

but it is not resolved.
