467	Transfer-Encoding: chunked и proxy_pass	Александр Гурьянов		"Добрый день у меня есть приложение на java которое использует в качестве сервера Netty. Это приложение возвращает простой ответ в режиме Transfer-Encoding: chunked. Все прекрасно работает если я использую это приложение напрямую. Когда я ставлю перед ним nginx, то ответ nginx всегда пустой. Настройки nginx у меня такие (http://serverfault.com/questions/159313/enabling-nginx-chunked-transfer-encoding/187573#187573):

location / {
  chunked_transfer_encoding on;
  proxy_buffering off;
  proxy_pass http://127.0.0.1:8000;
}

Тест сервера напрямую:
{{{

Я прогнал все через wireshark, но там тоже информации не много.
