HTTP headers are the components of the header section of request and response messages that are transmitted over HTTP. HTTP headers define the resources being requested, the behavior of the client or server, and the parameters of an HTTP transaction. You can add or remove HTTP headers if you configure DCDN to communicate with the origin over HTTP.
