Important note

The EdgeRules feature is available only on Enterprise plans.

As an additional security measure, you may want to restrict access to wp-admin locations. You can do this through custom path or IP address and reject access to the same locations through CDN:

<43>Nginx configuration block

location / {
        if ($request_uri ~ \/(wp-admin)\/.*) {                                  
            return 403;
        }
…
}

CURL to non-wp-admin location

curl -I http://cdn.domain.com/
