7. IANA Considerations

7.1. Header Field Registrations

HTTP header fields are registered within the "Message Headers" registry maintained at https://www.iana.org/assignments/message-headers/.

This document defines the following HTTP header fields, so their associated registry entries have been added according to the permanent registrations below (see [BCP90]):

Header Field NameProtocolStatusReference
Alt-SvchttpstandardSection 3
Alt-UsedhttpstandardSection 5

The change controller is: "IETF ([email protected]) -- Internet Engineering Task Force".

7.2. The ALTSVC HTTP/2 Frame Type

This document registers the ALTSVC frame type in the "HTTP/2 Frame Type" registry ([RFC7540], Section 11.2).

  • Frame Type: ALTSVC
  • Code: 0xa
  • Specification: Section 4 of this document

7.3. Alt-Svc Parameter Registry

The "Hypertext Transfer Protocol (HTTP) Alt-Svc Parameter Registry" defines the name space for parameters. It has been created and will be maintained at http://www.iana.org/assignments/http-alt-svc-parameters.

7.3.1. Procedure

A registration MUST include the following fields:

  • Parameter Name
  • Pointer to specification text

Values to be added to this name space require Expert Review (see [RFC5226], Section 4.1).

7.3.2. Registrations

The "Hypertext Transfer Protocol (HTTP) Alt-Svc Parameter Registry" has been populated with the registrations below:
