        # Alternative: With specific weights (higher weight = more traffic):
        # server 192.168.1.101 weight=2;  # This server will get more traffic
        # server 192.168.1.102;
        # server 192.168.1.103;

        # You can also configure additional settings like max_fails and fail_timeout:
        # server 192.168.1.101 max_fails=3 fail_timeout=10s;
        # server 192.168.1.102;
