This document describes a scheme that allows an HTTP client to
communicate its preferences for how the upstream server prioritizes
responses to its requests, and also allows a server to hint to a
downstream intermediary how its responses should be prioritized when
they are forwarded. This document defines the Priority header field
for communicating the initial priority in an HTTP version-independent
manner, as well as HTTP/2 and HTTP/3 frames for reprioritizing
responses. These share a common format structure that is designed to
provide future extensibility.
This document is a product of the HTTP Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
