How to tell nginx that the robots.txt file is on another server?

Question

Nginx

Hi everyone, there is a site site.com moved all the statics to a separate site.info server,
but I can’t configure nginx to give the robots.txt file from the site.info site when requesting it to site.com/robots.txt.
Tried:

location /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
        alias http://site.info/robots/robots.txt;
 }

and

location /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
        return 301 http://site.info/robots/robots.txt$request_uri;
 }

It turned out like this, but it seems to me that this is not correct, it just happens to be thrown to another site

location /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
        return http://site.info/robots/robots.txt;
 }

Tell me, maybe there are some options to not just transfer to another site, but to make an alias?

Answer 1

alias - specify a different folder on this server.
either use return for a redirect or proxy_pass, then nginx will pull the file from another server and give it to the client
