  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

  server {
      server_name  www.domain.net;
      location / {
          proxy_pass http://internal-www.domain.net;
      }
  }

  server {
      server_name  www.domain.com;
      location / {
          proxy_pass http://internal-com.domain.net;
      }
  }

  server {
      server_name  pub.domain.net;
      location /alias1/ {
          proxy_pass http://internal-pub.domain.net/;
      }
      location /alias2/ {
          proxy_pass http://internal-alias2.domain.net/;
      }
  }
