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 Name | Protocol | Status | Reference |
|---|---|---|---|
| Alt-Svc | http | standard | Section 3 |
| Alt-Used | http | standard | Section 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:
| Alt-Svc Parameter | Reference |
|---|---|
| ma | Section 3.1 |
| persist | Section 3.1 |
