Download limits on Nginx frontends

Browse Source 
Nginx frontend proxy servers by default limit the download size to 1 GB because of the default values of proxy_buffering and proxy_max_temp_file_size. These need to be either disabled via headers on the backend or the configuration on the frontend.

performance, place these on a separate hard drive that is dedicated to
swap and temp storage.
In case your site is behind a Nginx frontend (for example a loadbalancer):
By default, downloads will be limited to 1GB due to ``proxy_buffering`` and ``proxy_max_temp_file_size`` on the frontend.
* If you can access the frontend's configuration, disable `proxy_buffering <http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering>`_ or increase `proxy_max_temp_file_size <http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_max_temp_file_size>`_ from the default 1GB.
* If you do not have have access to the frontend, set the `X-Accel-Buffering <http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering>`_ header to ``add_header X-Accel-Buffering no;`` on your backend server.
