What is “origin policy”?

When there is a request for information through our CDN server, if CDN edge servers do not have the requested content, or the content has expired, the CDN edge servers will retrieve contents from the origin server. The communication method between the edge server and origin server is the “origin policy”

There are two options for Origin Policy:
HTTP – data transferred from the origin server to the edge server will not be encrypted.
HTTPS – data transferred from the origin server to the edge server will always be encrypted.
