HTTP/1.0 [<a href="#ref-3" title=""Hypertext Transfer Protocol -- HTTP/1.0"">3</a>] and HTTP/1.1 [<a href="#ref-11" title=""Hypertext Transfer Protocol -- HTTP/1.1"">11</a>] 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 [<a href="#ref-1" title=""Registration Procedures for Message Header Fields"">1</a>].
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.

<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>. IANA Considerations</span>
This specification provides initial registrations of HTTP header
fields in the "Permanent Message Header Field Registry", defined by
Registration Procedures for Message Header Fields [<a href="#ref-1" title=""Registration Procedures for Message Header Fields"">1</a>].
It also provides initial submissions of HTTP header fields in the
"Provisional Message Header Field Repository", defined by the same
document.
<span class="h2"><a class="selflink" id="section-4" href="#section-4">4</a>. Security Considerations</span>
No security considerations are introduced by this document beyond
those already inherent in use of the HTTP header fields referenced.
<span class="h2"><a class="selflink" id="section-5" href="#section-5">5</a>. Acknowledgements</span>
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.
