X-Gateway-Request-ID

The unofficial X-Gateway-Request-ID response header tags each response passing a hosting-side gateway with an opaque identifier. The header belongs to a four-header family beside X-Gateway-Cache-Status, X-Gateway-Cache-Key, and X-Gateway-Skip-Cache on WordPress hosting behind Cloudflare.

Usage

The identifier serves the same role as X-Request-ID elsewhere: quoting the value to the hosting provider's support locates the exact request in platform logs. Repeated values in crawl data appear on cache hits, where the stored response replays the identifier assigned at storage time rather than minting a fresh one per delivery.

Values

A 32-character lowercase hexadecimal string on every observed response, matching an MD5-length opaque token.

Example

X-Gateway-Request-ID: 47acfd8ba589f3dba85311a1e4e59c9f
