Websocket
This project provides a comprehensive implementation of the WebSocket protocol, enabling persistent, bidirectional communication between clients and servers. It handles the low-level complexities of the protocol, including the initial HTTP upgrade handshake and the encapsulation of data into discrete binary frames. By managing these connections, it allows applications to exchange data instantly without the overhead associated with repeated standard request cycles.
The library distinguishes itself through its focus on high-frequency message exchange and concurrent connection management. It utilizes internal memory buffers to optimize network throughput and minimize system calls, while employing lightweight execution threads to maintain independent state for multiple active clients simultaneously. To ensure data integrity and compatibility, it also manages masking-based payload obfuscation for client-sent frames.
Beyond core protocol support, the project includes a suite of web toolkit capabilities for building complete network applications. This includes mechanisms for routing HTTP requests, processing traffic through reusable middleware layers, and managing user sessions. It also supports remote procedure invocation, form data binding, and security features such as request forgery prevention and encrypted cookie handling.
