HTTP/1.1 Client Library
Overview

HTTP Client library

This HTTP Client library implements a subset of the HTTP/1.1 protocol. Features of this library include:

  • Fully synchronous API, to allow applications to completely manage their concurrency and multi-threading.
  • Operations on user supplied buffers, so that applications have complete control of their memory allocation strategy.
  • Integration with http-parser to handle chunked encoding.

Feature of HTTP/1.1 not supported in this library:

  • Streaming uploads and downloads. Range requests for partial content responses are highly encouraged with this API.
  • Pipelining requests. There may be only one request outgoing and one response incoming, at a time, on a connection.
  • Automatic redirection. The user application owns their connection and must handle redirection status codes.
