Internet-Draft          HTTP header registration               June 2002


1. Introduction

   This document defines IANA registration for a number of HTTP message
   header fields, per Registration procedures for message header fields
   [1].

   [[[The main body of this document is automatically generated.  Some
   sample HTML registry pages have been prepared from the same data, and
   can be found at  [3].]]]

1.1 Structure of this document

   Section Section 2 contains the submission for initial registration of
   HTTP related message headers fields.

1.2 Document terminology and conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [2].

      NOTE: indented comments like this provide additional nonessential
      information about the rationale behind this document.

   [[[Editorial comments and questions about outstanding issues are
   provided in triple brackets like this.  These working comments should
   be resolved and removed prior to final publication.]]]

2. Registration templates

   Header registry entries are summarized in tabular form for
   convenience of reference, and presented in full in the following
   sections.

3. IANA considerations

   This specification provides an initial registration of HTTP headers
   in the two registries defined by Registration procedures for message
   headers [1]:

   o  IANA registry for normative message headers, and

   o  IANA registry for provisional message headers.


4. Security considerations

   No security considerations are introduced by this specification
   beyond those already inherent in the use of message headers.

5. Acknowledgements

   The author gratefully acknowledges the contributions of: Graham
   Klyne, who provided the software and support to generate the
   registries; Jeff Mogul, for review of the earlier drafts; and Anja
   Feldman.
