You never notice your ISPs forward CDN because it follows standards. A reverse CDN like MaxCDN would also work transparently if it followed standards. Because it doesn't, they provide instructions for modifying your site to work around the most obvious problems. The less obvious issues are up to you to figure out after you notice them.
