[Help Me] Convert htaccess to nginx

I want to convert this to nginx rules

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?domain.com [NC]
RewriteRule .(jpg|jpeg|png|gif)$ - [NC,F,L]

I’ve tried to put this on the web but I can not even open.

if ($http_referer !~ "^$"){
set $rule_0 1$rule_0;
}
if ($http_referer !~* "^http(s)?://(www.)?domain.com"){
set $rule_0 2$rule_0;
}
if ($rule_0 = "21"){
return 403;
break;
}

Hi!

I’m guessing these rules are there to stop people from hotlinking images hosted on your site? In some cases, writing the rules with nginx in mind is better than converting already-written htaccess/Apache rules.

Luckily, nginx supports referrer whitelisting by default. Use the following code:

location ~ .(gif|png|jpe?g)$ {
     valid_referers none blocked domain.com www.domain.com;
     if ($invalid_referer) {
        return 403;
    }
}

Make sure to restart nginx so that the changes take effect:

sudo service nginx restart
