CDNs and domains
- by Martind
Hi all!
A lot of big websites (facebook etc) are settings up CDN's for their content. Now I notice, that these CDN's are not always on the original domain.
Example: Facebook pictures are on "photos-a.ak.fbcdn.net"
Why is that? Is there a performance-gain in not having lots of subdomains on the "primary" domain (facebook.com)
