How to solve [Serve the following static resources from a domain that doesn't set cookies]

Question

I'm struggling in something i don't know at all. When the time i ping my website, i got this result: [Serve the following static resources from a domain that doesn't set cookies:]. And, this result caused from the images which i used for background images. I tried to google about this topic but all the answers seem to be difficult to understand of. Does anyone here knows about it and any simple solution to fix it up?

Answer 1

Generally, when you are serving content such as images, JavaScript, CSS, there is no reason for a HTTP cookie to accompany it, as it creates additional overhead. That is why a lot of tools report this. Here are two quick and easy options:

Option 1 - Use a CDN

Use a CDN to host your images which has the ability to ignore cookies as well as strip cookies which will completely prevent the client from receiving the Set-Cookie response header. Note: You can't disable cookies on Cloudflare.

Option 2 - Point Static Assets to New Domain

This is an example with WordPress.

1. First, create a subdomain such as static.domain.com. This is where you will deliver all your files from.
2. Point your subdomain to your /wp-content directory with a CNAME.
3. Edit your wp-config.php file to reflect the following:

define("WP_CONTENT_URL", "http://static.domain.com"); 
define("COOKIE_DOMAIN", "domain.com");
