prestashop 1.7 on nginx behind HAproxy with SSL termination

[lukaszte]

Hi.
How to configure prestashop 1.7 on nginx behind HAproxy with SSL termination?
I have redirects loop http->https->http->... - when enabled http-request add-header X-Forwarded-Proto https if { ssl_fc }
or I have mixed content (CSS and JS on http) - when disabled http-request add-header X-Forwarded-Proto https if { ssl_fc }
At this moment prestashop have disabled SSL.
It looks like Presta doesn't know that it work via https, is there any header I can set on HAProxy when is terminating https to inform Prestashop that HTTPS is used?

Nginx configuration:  

server {

    listen 80;
    root /var/www/multistore;


    # Add index.php to the list if you are using PHP
    index index.html index.php index.htm index.nginx-debian.html;

    server_name mysite.tld;



    # Redirect 404 errors to prestashop
    error_page 404 /index.php?controller=404;

    # Gzip Settings, convert all types.
    gzip on;
    gzip_vary on;

HAProxy configuration:

frontend http_front
   bind :80
   bind :443 ssl crt /etc/pki/tls/certs/  
   mode http
   http-request add-header X-CLIENT-IP %[src]
   http-request add-header X-REAL-IP %[src]
   http-request add-header X-Forwarded-Host %[req.hdr(host)]
   http-request add-header X-Forwarded-Server %[req.hdr(host)]
   http-request redirect scheme https code 301 unless { ssl_fc }
   default_backend http_back

backend http_back
   balance roundrobin
   option httpclose
   redirect scheme https if !{ ssl_fc }
   http-request set-header X-Forwarded-Port %[dst_port]
   http-request add-header X-Forwarded-Proto https if { ssl_fc }
   http-request set-header Strict-Transport-Security \ max-age=31536000;\ includeSubDomains;\ preload
   server backend1 192.168.0.1:80 check
   server backend2 192.168.0.2:80 check

And solved, the solution is to add this header in frontend section on haproxy:

http-request add-header SSL on if { ssl_fc }

So now section is looking like:

frontend http_front
   bind :80
   bind :443 ssl crt /etc/pki/tls/certs/  
   mode http
   http-request add-header X-CLIENT-IP %[src]
   http-request add-header X-REAL-IP %[src]
   http-request add-header X-Forwarded-Host %[req.hdr(host)]
   http-request add-header X-Forwarded-Server %[req.hdr(host)]
   http-request redirect scheme https code 301 unless { ssl_fc }
   http-request add-header SSL on if { ssl_fc }
   default_backend http_back
