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,
