Using in Staging/Testing sites
If your domain matches any of the following patterns, it will not be counted towards the number of sites in a license.
For example, if you've bought the personal plan (single site), it can be activated in "example.com" and "staging.example.com"
Note: FlyingCDN subscription is tied to the URL you've set as origin. Using it in another domain (even a staging site) will result in a 404.
