Why in Nginx the limit_rate parameter may not work for http requests?

Question

Nginx

Good afternoon.
I limited the speed for the /uploads/ folder by adding a parameter to the Nginx config limit_rate 350k;
When uploading a file using the https protocol https://mysite.ru/download.php?file=some_file.zip, the restriction works correctly, everything is fine, but if you try to upload via http, that is http://mysite.ru/download.php?file=some_file.zip, there is no restriction anymore and the file is downloaded at maximum speed.
Please advise why this is happening and how it can be fixed?

    location @fallback {

    location ~ /\.ht    {return 404;}
    location ~ /\.svn/  {return 404;}
    location ~ /\.git/  {return 404;}
    location ~ /\.hg/   {return 404;}
    location ~ /\.bzr/  {return 404;}

    include /home/admin/conf/web/nginx.mysite.ru.conf*;
}

You have a directive in the location /uploads/, under which the download url does not fall. Take it higher or to the correct location.
