WebServer
This is a high-performance C++ HTTP web server designed for delivering static content. It operates as an asynchronous event loop server that combines IO multiplexing with worker thread pools to handle concurrent requests without blocking.
The server specializes in TCP connection management, featuring keep-alive sessions, request pipelining, and timer-based timeout tracking for idle sockets. To ensure high throughput, it utilizes double-buffered asynchronous logging and background threads to prevent disk I/O latency from impacting network traffic.
The system covers broad capability areas including static resource delivery, concurrent connection management, and network resource tracking to reclaim system memory and available sockets.
Features
- Static Content Delivery - Designed as a high-performance server for the delivery of static files and resources to web clients.
- IO Multiplexing - Employs IO multiplexing to monitor multiple network sockets on a single thread, enabling high concurrency.
- HTTP Keep-Alive Connections - Optimizes TCP connectivity through HTTP keep-alive sessions and request pipelining.
- Persistent HTTP Connections - Maintains persistent TCP keep-alive sessions to reduce the overhead of repeated handshakes for multiple HTTP requests.
- Persistent TCP Connections - Enables multiple requests over a single TCP session using long-lived connections and request pipelining for high performance.
- Asynchronous Event Loops - Operates as an asynchronous event loop server to handle concurrent network requests without blocking.
- Asynchronous Task Processing - Distributes network events to a worker thread pool via a synchronized queue for asynchronous task processing.
- Concurrent Request Pools - Processes multiple simultaneous client requests using a combined approach of thread pools and IO multiplexing.
- Static Worker Pools - Distributes incoming network events to a fixed-size pool of pre-allocated worker threads to ensure non-blocking request handling.
- High-Performance HTTP Servers - A high-performance C++ implementation optimized for low-latency static content delivery.
- Static File Servers - Serves static assets from designated directories using a concurrent thread pool architecture.
- Double-Buffered Log Writing - Uses a double-buffered asynchronous logging system to record server events without interrupting the primary execution flow.
- Connection Termination - Gracefully handles connection termination by detecting closed sockets and flushing remaining data before releasing resources.
- Idle - Implements a timer-heap system to monitor connection idle times and automatically close unresponsive sockets to reclaim memory.
- Request Timeout Management - Implements request timeout management to automatically close inactive connections and reclaim system resources.
- TCP Session Management - Manages TCP session state, including keep-alive durations and request pipelining for optimized socket usage.
- Background I/O Queues - Implements a background I/O queue to offload file system writes and prevent storage latency from blocking network traffic.
- Event Logging - Implements event logging to track server activity and requests using asynchronous background writes.
- Connection Timeout Heaps - Manages connection timeouts using a priority queue (timer-heap) to reclaim system memory and sockets from idle clients.
- Asynchronous Logging - Provides a non-blocking asynchronous logging workflow to prevent disk I/O from impacting network performance.
Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
