Introduction

The HttpServerAsyncIo module provides async I/O poll operations for the HttpServer module, enabling high-performance non-blocking I/O for HTTP, SSE, and WebSocket connections.

This module leverages the Qore::AbstractPollOperation pattern and integrates with AsyncSocketIoController for efficient multiplexed I/O handling.

Components

• HttpAcceptPollOperation - Composite operation for accept + SSL + ALPN negotiation
• Http2PollOperation - HTTP/2 server connection handling
• HttpIdlePollOperation - Monitors idle keep-alive connections
• HttpSseStreamPollOperation - SSE streaming support (HTTP/1.x)
• HttpWebSocketPollOperation - WebSocket bidirectional I/O (HTTP/1.x)
• HttpAsyncTarget - Callback interface for HTTP events
• HttpAsyncSocketIoController - HTTP-aware I/O controller

Protocol-Agnostic Abstractions

These abstract classes provide a unified interface for SSE and WebSocket connections regardless of the underlying HTTP protocol version (HTTP/1.x or HTTP/2):

• AbstractSseConnection - Protocol-agnostic SSE interface
• AbstractWebSocketConnection - Protocol-agnostic WebSocket interface
• Http1SseConnection - HTTP/1.x SSE wrapper
• Http1WebSocketConnection - HTTP/1.x WebSocket wrapper
