Acknowledgements ...............................................49 6. Informative References .........................................49 1. Introduction HTTP/1.0 [3] and HTTP/1.1 [11] define protocol constructs (respectively, the HTTP-header and message-header BNF rules) that are used as message headers. These specifications also define a number of HTTP headers themselves, and they provide for extension through the use of new field-names. This document defines the initial contents of an IANA registry that catalogs permanent HTTP header field-names, and of an IANA repository that catalogs provisional HTTP header field-names. Both are operated according to Registration Procedures for Message Header Fields [1]. Note that neither tracks the syntax or semantics of field-values. Also, while some HTTP headers have different semantics depending on their context (e.g., Cache-Control in requests and responses), both registries consider the HTTP header field-name name space singular. Also, some contact details listed may no longer be correct. 2. Registration Templates Header field entries are summarized in tabular form for convenience of reference and presented in full in the following sections. Nottingham & Mogul Informational [Page 4]

RFC 4229 HTTP Header Fields December 2005 3. IANA Considerations This specification provides initial registrations of HTTP header fields in the "Permanent Message Header Field Registry", defined by Registration Procedures for Message Header Fields [1]. It also provides initial submissions of HTTP header fields in the "Provisional Message Header Field Repository", defined by the same document. 4. Security Considerations No security considerations are introduced by this document beyond those already inherent in use of the HTTP header fields referenced. 5. Acknowledgements The authors would like to thank Graham Klyne for his work in defining the message header registries, his input and help in preparing this document, and the registry generation software. 6.
