Hi Francis, Thanks for the reply.

My file is like this.

upstream webgateway {
   keepalive 10;

server {
   listen 9191;
   server_name proxy.lab.local;

   location / {

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Request-URI $request_uri;
        proxy_redirect off;

        proxy_pass http://webgateway;

I'm able to open HTTP requests in the client's browser.
The problem is being the HTTPS requests.
Is there any way for NGINX to receive the traffic and forward it (balanced)
to the proxy servers?
A simpler way. That way I could include the Web Gateway certificate in the
Windows client.

Thank You!
