nginx и ntop

[Dmitry Ivanov <nginx-ru@xxxxxxxxxxxx>]

Здравствуйте, All.

Решил перед веб-интерфейсом ntop поставить nginx

nginx version: nginx/0.8.54

location /ntop    {
            proxy_pass    http://127.0.0.1:3000;
            proxy_set_header Host $http_host;
            proxy_intercept_errors on;
            chunked_transfer_encoding off;
        }

ntop, как известно, разговаривает на HTTP 1.0

В итоге получаю:

# wget --spider -S 127.0.0.1:3000
Spider mode enabled. Check if remote file exists.
--2011-04-08 13:52:50--  http://127.0.0.1:3000/

2011-04-08 13:52:56 (9.25 KB/s) - `index.html' saved [43200]

Тут wget, получив HTTP/1.0 501 Not Implemented, делает новый запрос
уже по 1.0 и все ОК.

Далее:

# wget --spider -S firma.ru/ntop
Spider mode enabled. Check if remote file exists.

  Connection: keep-alive
Remote file does not exist -- broken link!!!

Т.е. nginx возвращает 501 от бэкенда в HTTP 1.1, еще один запрос и в
логах

upstream prematurely closed connection while reading response header from 
upstream

Как подружить nginx и бэкенд, работающий только по HTTP 1.0?

Спасибо.
