Headers can be added or altered at each layer of the CDN. You must tell us four things: the action, the header name, the header value, and the direction to apply. The action will tell us whether we are adding, removing, or replacing headers. The header name and header value will determine the full header text. The direction will determine whether we add it before we respond to a request or before we make a request further up the chain in the server hierarchy. Examples include:
- Action: Set
- Header Name: Host
- Header Value: code_abc123
- Direction: Mid Request to Origin
