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.

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.
