}

server {
    listen       80;
    server_name  www.mydomain.com;
    root         /usr/share/nginx/html;
    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;
    location / {
        proxy_set_header Host $host:$proxy_port;#proxy_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://myserver;
    }
    error_page 404 /404.html;
        location = /40x.html {
    }
    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
