For non topology-based delivery services, headers can be added or altered at the mid layer of the CDN. You must tell us three things: the action, the header name, and the header value. 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. Mid header rewrite values will be added before we make a request further up the chain in the server hierarchy (ie. to the origin). Examples include:
- Action: Set
- Header Name: Host
- Header Value: code_abc123

Mid Header Rewrite Rules.
