H2H2 is a high-performance, memory-efficient, and scalable HTTP/2 implementation for OCaml. It is based on the concepts in http/af, and therefore uses the Angstrom and Faraday libraries to implement the parsing and serialization layers of the HTTP/2 standard. It also preserves the same API as http/af wherever possible.
HttpafHttp/af is a high-performance, memory-efficient, and scalable web server for OCaml. It implements the HTTP 1.1 specification with respect to parsing, serialization, and connection pipelining. For compatibility, http/af respects the imperatives of the Server_connection header when handling HTTP 1.0 connections.
