According to documentation (http://nginx.org/en/docs/http/ngx_http_addition_module.html) add_before_body/add_after_body does a subrequest.

So something like that might work (I don't have an nginx instance with particular module compiled so you'll have to test yourself) - eg have a (internal) named location with a proxy_pass to the remote url:


location @beforebody {
    proxy_pass http://externalserver/somefile.txt;
}

location / {
        try_files $uri $uri/ =404;
        add_before_body @beforebody;
}
