Dear all,
I have made 3 containers containing an API which has a delay page that simulates 25 seconds of delay and when I send a request in browser, I understand which container is going to reply in the logs and within that 25 seconds,I stop the destination container but nginx rotates the request to another healthy container and gives me the correct output after 25 seconds but how?
Is it just rever proxy that I have set or it is working by circuit hreaker?
It cannot be circuit breaker because I am using nginx not nginxplus and as far as I know, nginx does not support circuit breaker pattern and it is just available in nginx plus.
Please help me solve the doubt in my mind and let me know if I can have any control upon this functionality of nginx.

Thanks
