Mysterion,

# You should look at the following URL's in order to grasp a solid understanding

# Generally, you will want to move this file somewhere, and start with a clean

SagePtr, Nginx Unit

avp dnepr, 6 часов назад был добавлен коммит с недостающей переменной:
https://github.com/nginx/unit

SagePtr, Mysterion, спасибо большое. А как мне обновить пакет Nginx Unit через Git

SagePtr, Mysterion, также пожалуйста подскажите как сделать следующее в этом конфиге.
Чтоб скрипты шли через обработчик, а статика напрямую (без обработчика)

Почему то не хочет обрабатывать стили. Вероятно Nginx Unit не умеет правильно обработать стили.
Надо напрямую
