Special headers and X-Accel-Redirect

Hi guys,
I have small problem with file download using X-Accel-Redirect. I am
using Nginx as proxy before some REST API application, some of the
requests are for big files which are located at other host - so I am
using X-Accel-Redirect to download them. But I have also some metadata
connected with file which I want to return in X-metadata header from
REST API.
So, here is my config:
server {
listen 80;
listen 443 ssl;
server_name some-service.pl;
ssl_certificate /etc/ssl/certs/some-service.pl.pem;
ssl_certificate_key /etc/ssl/private/some-service.pl.key;
client_max_body_size 100M;
client_body_buffer_size 128k;
location / {
if ($http_x_user = "") {
return 502;
}
proxy_pass http://api;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for; # client, proxy1, proxy2, ...
}
location /files {
internal;
rewrite ^/files(.*)$ $1 break;
proxy_pass http://filestore;
proxy_hide_header Content-Type;
proxy_hide_header Content-Disposition;
set $x_metadata $upstream_http_x_metadata;
add_header X-metadata $x_metadata;
}
}
I am using this trick with set to temporary variable and add_header
with this variable (which I've found somewhere on this list), but this
is not working. Even simple:
set $x_std "testest";
add_header X-metadata $x_std;
does not work for me.
Could please somebody tell me what could be wrong?
Thanks,
