    I have been trying to set this up on my website https://focoseo.com and can not seem to get this to work.

    I created static.focoseo.com and set the document root to /public_html/wp-content

    I then added the following to my wp-config.php file:
    define(“WP_CONTENT_URL”, “https://static.focoseo.com”);
    define(“COOKIE_DOMAIN”, “www.focoseo.com”);

    I have tried several different variations and it’s still not showing me anything different when I run a site speed check.

    Any help would be greatly appreciated!

    Can you also give the same tips for Secure Site. Because it does not work for my site (https://www.hewata.com).

    My site use Let’s Encrypt SSL included in my cPanel which cover hewata.com http://www.hewata.com mail.hewata.com

    When I create static.hewata.com which is non secure site, it is not included in the certificate.

    Hope you can help.

    Hello Suanlian,
    I am not using wordpress. Can you show me what step to follow after creating the Subdomain?

    Thank you very much!

    Hi Suanlian!

    Finally a step by step guide! 😉

    But I need one more information: if I have more domains on my cpanel what I have to write on step d?

    public_html/wp-content or public_html/example.com/wp-content?

    Thank’s so much!

      Hi Enrico,

      Both works, it depends on the website root.

      For Eg, If your website root is wp-content you can used public_html/wp-content. But if your website is locate in wp-content/example.com you have to used public_html/example.com/wp-content
