This page states:
" long as you have the strip cookies option enabled, even if you receive this warning it will be incorrect. YSlow does not take into consideration that the CDN actually strips the cookie and therefore may continue to throw the error. However, if you run a cURL command on the asset or check it within the Chrome Dev tools Network tab, you won’t see any Set-Cookie headers. Therefore this YSlow warning can be safely ignored."

Does anyone know anything about my point#2?
What if I just want a cookie-free domain to point to a subfolder in my main domain? Can we easily do this in Virtualmin?
