To block hotlink protection or bandwidth stealing, you can add the following to the server configuration of your website.
valid_referers yourdomain.tld www.yourdomain.tld;
if ($invalid_referer) {
return 403;
}
If you need to allow hotlinks from a specific domain, you can edit the valid_referers line and add the URL. For allowing access without any referral, you can use “none” instead of the domain name. For example
valid_referers none yourdomain.tld www.yourdomain.tld;
If you only want to limit access to images and videos, you can put the above code in a location block like
location ~* \.(mp4|gif|png|jpg|jpeg|css|ico)$ {
valid_referers yourdomain.tld www.yourdomain.tld;
if ($invalid_referer) {
return 403;
}
}
