An HTTP/2 implementation for GNU libmicrohttpd.
HTTP/2 is the lastest version of the HTTP protocol. Its main feature is the use of a single connection between a client and a server. Major changes have been introduced in HTTP/2, such as frames, multiplexing, flow control, prioritization and header compression, making it very different from its predecessor HTTP/1.
GNU libmicrohttpd (MHD) is a small and fast C library that implements HTTP server functionality. Some of its implementation characteristics include: different threading models, a reentrant API, fully HTTP/1.0 and HTTP/1.1 compliant.
MHD can be used in different platforms and in embedded systems without thread support, thanks to its small binary size and high performance.
The goal of this project is to add HTTP/2 support to MHD.
The HTTP/2 stack is already implemented by an existing library nghttp2, used by well-known projects such as curl. I will use this library for the low level protocol handling parts and write the functionality to handle the HTTP/2 connections.
MHD has a tightly coupled implementation of HTTP/1, so adding HTTP/2 support is not straightforward. I will create an interface between the TCP connection and the HTTP protocol, in order to have an easy and transparent way to switch between protocols (especially to support an HTTP/2 upgrade).
