I am trying to use NGINX as reverse proxy for streaming using QuickTime
and rtsp over http.
QuicKTime send an http GET to my reverse proxy in a public zone, then my
reverse proxy send the request to my video server in a private zone.
What I can see is that the http GET request is received by NGINX on the
reverse proxy, then by my video server, which responds immediately with
a 200 OK.
This response is received by the reverse proxy, but it seems that NGINX
block the response. (see log file attached).

Other http traffic is executed without any problem, problems occurs only
with rtsp over http.

The http headers of the http GET send by QuickTime are:
User-Agent: QuickTime/7.7 (qtver=7.7;os=Windows NT 5.1Service Pack 3)
x-sessioncookie: 4qqv28gOAABf4EQBBoAAAA
Accept: application/x-rtsp-tunnelled
Pragma: no-cache
Cache-Control: no-cache

Here is my NGINX configuration:

------- /etc/nginx/nginx.conf BEGIN -------
worker_processes  1;
error_log       /var/log/nginx/error.log ;

pid    /var/run/nginx/nginx.pid;

events {
    worker_connections  1024;

http {
    include       mime.types;
    default_type  application/octet-stream;
    access_log  /var/log/nginx/access.log;
    sendfile        on;

    keepalive_timeout  65;

    gzip            on;
    #gzip            off;
    gzip_min_length  1000;
    #gzip_buffers     4 8k;
    #gzip_http_version 1.0;
    gzip_comp_level 3;
    gzip_proxied any;
    #gzip_types      text/plain application/xml;
    gzip_types  text/plain text/css application/json
application/x-javascript text/xml application/xml application/xml+rss
    gzip_vary         on;

   include /etc/nginx/sites-enabled/*;
   include /etc/nginx/proxy.conf;
------- /etc/nginx/nginx.conf END  -------

------- /etc/nginx/proxy.conf BEGIN  -------
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    10m;
client_body_buffer_size 128k;
proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffers           32 4k;
------- /etc/nginx/proxy.conf END  -------

------- /etc/nginx/sites-enabled/video.conf BEGIN  -------
upstream video
    server_name <public-ip>;
    location /
         proxy_pass http://video;
        error_log /var/log/nginx/errori debug;
------- /etc/nginx/sites-enabled/video.conf END  -------

Thank's for your help...
