Variable: CMCD_HEADER_MAP

const CMCD_HEADER_MAP: Record<CmcdRequestKey | "nrr", CmcdHeaderField>;

Defined in: CMCD_HEADER_MAP.ts:19

The map of CMCD keys to their appropriate header shard.

Event-only keys (e, ts, cen, h) and response-received keys (rc, ttfb, ttlb, url, and others) are intentionally absent. They are transmitted in the event-mode POST body, not HTTP headers.
