RFC 9113: HTTP/2
Proposed Standard
M. Thomson
C. Benfield
June 2022
IETF publication
Web and Internet Transport
Abstract
This specification describes an optimized expression of the semantics of the Hypertext Transfer Protocol (HTTP), referred to as HTTP version 2 (HTTP/2). HTTP/2 enables a more efficient use of network resources and a reduced latency by introducing field compression and allowing multiple concurrent exchanges on the same connection.
This document obsoletes RFCs 7540 and 8740.

RFC 8740: Using TLS 1.3 with HTTP/2
Proposed Standard
D. Benjamin
February 2020
IETF publication
Web and Internet Transport
Abstract
This document updates RFC 7540 by forbidding TLS 1.3 post-handshake authentication, as an analog to the existing TLS 1.2 renegotiation restriction.

September 2018
IETF publication
Web and Internet Transport
Abstract
This document defines a mechanism for running the WebSocket Protocol (RFC 6455) over a single stream of an HTTP/2 connection.

RFC 8336: The ORIGIN HTTP/2 Frame
Proposed Standard
M. Nottingham
E. Nygren
March 2018
IETF publication
Web and Internet Transport
Abstract
This document specifies the ORIGIN frame for HTTP/2, to indicate what origins are available on a given connection.

RFC 8164: Opportunistic Security for HTTP/2
Historic
M. Nottingham
M. Thomson
May 2017
IETF publication
Web and Internet Transport
Abstract
This document describes how "http" URIs can be accessed using Transport Layer Security (TLS) and HTTP/2 to mitigate pervasive monitoring attacks. This mechanism not a replacement for "https" URIs; it is vulnerable to active attacks.

RFC 7540: Hypertext Transfer Protocol Version 2 (HTTP/2)
Proposed Standard
M. Belshe
R. Peon
M. Thomson
May 2015
IETF publication
Web and Internet Transport
Abstract
This specification describes an optimized expression of the semantics of the Hypertext Transfer Protocol (HTTP), referred to as HTTP version 2 (HTTP/2). HTTP/2 enables a more efficient use of network resources and a reduced perception of latency by introducing header field compression and allowing multiple concurrent exchanges on the same connection. It also introduces unsolicited push of representations from servers to clients.
This specification is an alternative to, but does not obsolete, the HTTP/1.1 message syntax. HTTP's existing semantics remain unchanged.

RFC 7541: HPACK: Header Compression for HTTP/2
Proposed Standard
R. Peon
H. Ruellan
May 2015
IETF publication

Abstract
This specification defines HPACK, a compression format for efficiently representing HTTP header fields, to be used in HTTP/2.
