RE: How To Use Cookie-Free Domains in WordPress?
Use cookie-free domains in WordPress:
1.Create a subdomain such as static.example.com which is where you will deliver all your static files from.
2.Point your new subdomain to the /wp-content directory of your WordPress installation. For cPanel users, you will need to update the document root field from public_html/static to public_html/wp-content.
3.Edit wp-config.php file as below:
define("WP_CONTENT_URL", "http://static.example.com"); define("COOKIE_DOMAIN", "example.com");
4.Run the following command in your SQL database.
UPDATE wp_posts SET post_content = REPLACE(post_content,'example.com/wp-content/','static.example.com/')
Your cookie domain and static content subdomain are set.Now you can begin delivering static content without the server setting an unnecessary cookie for static assets.
