Конфигурация апстрима вот такая:
upstream my_backends {

server 1.2.3.6:80 backup;
server 1.2.3.7:80 backup;
server 1.2.3.8:80 backup;
}
Я правильно понимаю, что апстрим знает только про последний
запрошенный бэкенд и может отправлять один запрос по кругу даже на те
бэкенды, которые ранее на него вернули ошибку?
