5. IANA Considerations
IANA has created the "HTTP Cache-Status" registry at <https://www.iana.org/assignments/http-cache-status> and populated it with the types defined in Section 2; see Section 4 for its associated procedures.
IANA has added the following entry in the "Hypertext Transfer Protocol (HTTP) Field Name Registry" defined in [HTTP], Section 18.4:
Field name: Cache-Status
Status: permanent
