Enabling nginx Chunked Transfer Encoding

It looks like nginx 0.8.35 may support chunked transfer encoding:

Changes with nginx 0.8.35 01 Apr 2010

*) Change: now the charset filter runs before the SSI filter.

*) Feature: the "chunked_transfer_encoding" directive.

This is great, because I'm trying to get push git changes through an nginx reverse proxy to a git-http-backend process. Git HTTP takes advantage of chunked transfer encoding for client-side efficiency reasons.

However, I can't get it to work. I'm using nginx 0.8.44 on Debian Lenny with the following configure invocation:

./configure \
--sbin-path=/usr/sbin \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--user=www-data \
--group=www-data \
--p开发者_StackOverflow中文版id-path=/var/run/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--with-http_ssl_module \
--with-http_gzip_static_module \
--with-http_realip_module

And the following conf file:

server {
    server_name example.com;
    location / {
        proxy_pass  http://192.168.0.10;
        include     /etc/nginx/proxy.conf;
        chunked_transfer_encoding on;
    }
}

And my proxy.conf looks like this:

proxy_redirect          off;
proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size    100M;
client_body_buffer_size 128k;
proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffer_size       4k;
proxy_buffers           4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

I asked the same question on ServerFault and got this answer:

I believe chunked_transfer_encoding is on by default. The configuration flag works properly when added to the server{} scope and is not valid when placed in the location{} scope.
