If you configure CDN to use HTTP to communicate with your origin, you can add or remove HTTP header fields.

Background information

HTTP headers are the header component in the request and response messages sent over Hypertext Transfer Protocol (HTTP). HTTP header fields describe the requested resources, the information of the client or server, and the parameters of an HTTP transaction.

HTTP headers include general headers, request headers, and response headers.
