Nginx, turn off cache for a specific file

Question

location /static {
    alias /home/ubuntu/Documents/zibann/momsite/momsite/static; # your Django project's static files - amend as required
    if ($uri ~* ".*config.js") {
       expires off;
    }

    if ($uri ~* ".*\.(js|css|png|jpg|jpeg|gif|swf|svg)" ) {
       access_log off;
       expires 365d;
       add_header Cache-Control public;
    }

}

Hoping config.js would not get cached, but it does.
How can I exclude one file from being cached?

Answer 1

Make a separate location block for config.js above the others.

location ~ config\.js {
    alias xyz;
    expires off;
}

location static etc
