Async Http Client
This is a non-blocking network client for Java applications that provides asynchronous HTTP request capabilities and bidirectional WebSocket connectivity. It leverages a Netty-based architecture to handle high volumes of network input and output.
The library utilizes native transport abstractions such as Epoll, KQueue, and io_uring to reduce system latency. It supports HTTP/2 multiplexing to run multiple concurrent request-response streams over a single connection and provides automatic response body decompression for various formats.
Core capabilities cover the management of complex network tasks, including multipart data uploads, request body streaming, and resumable downloads. The project also includes utilities for proxy routing, request authentication, cookie management, and a pipeline for filtering and transforming network traffic.
Features
