HTTP/2

This directory contains C++ code implementing the HTTP/2 protocol.

Much of this code was written originally as a collaboration between the Chromium networking and Google Front End teams while developing the experimental SPDY protocol. SPDY was later standardized as HTTP/2.

`http2/adapter/`

This subdirectory contains general purpose HTTP/2 protocol handling libraries. The oghttp2_adapter library can be used in combination with an event loop, a TLS library, and a socket library to make a complete HTTP/2 client or server.

`http2/core/`

This subdirectory contains core utilities, including constants, data structures, and some common entry points that can be used to parse and serialize HTTP/2 protocol elements.

`http2/decoder`

This subdirectory contains a decoder for the HTTP/2 wire format, written from scratch by James Synge. This decoder is used by Chromium-based browsers, the Google Front End reverse-proxy, and Envoy-based proxies.

`http2/hpack`

This subdirectory contains a decoder and encoder for the HPACK compression algorithm

`http2/test_tools`

This subdirectory contains test utilities that facilitate writing unit tests for code in the other subdirectories.
