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 llhttp 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.
