   2 (HTTP/2), and an associated error code for handling invalid
   encoding.

1.  Introduction

   This document introduces a mechanism for applying gzip encoding
   [RFC1952] to data transported between two endpoints in the Hypertext
   Transfer Protocol Version 2 (HTTP/2) [RFC7540], analogous to
   Transfer-Encoding in HTTP/1.1 [RFC7230].

1.1.  Notational Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this

2.  Additions to HTTP/2

   This document introduces a new HTTP/2 frame type ([RFC7540],
   Section 11.2), a new HTTP/2 setting ([RFC7540], Section 11.3), and a
   new HTTP/2 error code ([RFC7540], Section 7), to allow the
   compression of data.
