Set CNAME DNS Records
After adding a domain or a subdomain/hostname to a CacheFly service, you (or your hosting provider) must make changes to your DNS Zone File to point requests to your CacheFly service, usually using a CNAME record.
For example:
If your service name is mycompany, and you have added static.mydomain.com to your service, you can configure:
static.mydomain.com. 86400 CNAME mycompany.cachefly.net
in your DNS Zone File.
As a result, content previously available via static.mydomain.com will now be available from mycompany.cachefly.net.
For example, the asset http://static.mydomain.com/images/example.jpg will now be available at http://mycompany.cachefly.net/images/example.jpg.
