Apache Traffic Server

Apache Traffic Server is a high-performance, scalable, and extensible HTTP/1.1 and HTTP/2 compliant caching proxy server. Originally developed as a commercial product by Yahoo!, it was donated to the Apache Software Foundation and is now widely used by major content delivery networks and enterprises to accelerate web traffic and reduce infrastructure load.

Features

• Caching Engine: Efficiently caches frequently requested content to reduce latency and bandwidth usage.
• Forward and Reverse Proxy Support: Operates as both a forward and reverse proxy, enabling flexible deployment scenarios.
• HTTP/2 Compliance: Supports modern web protocols for improved performance and compatibility.
• Plugin Architecture: Extensible via APIs that allow custom plugins for header manipulation, cache algorithms, and more.
• Traffic Routing and Filtering: Enables content filtering, anonymization, and load balancing.
• Logging and Monitoring Tools: Built-in support for detailed traffic analysis and system diagnostics.

Capabilities

• High Throughput: Capable of handling tens of thousands of requests per second on modern hardware.
• Scalability: Designed to scale across multi-core systems and large network infrastructures.
• Security Features: Supports secure communication and access control mechanisms.
• Custom Configuration: Highly configurable via text-based configuration files and runtime variables.
• Protocol Handling: Manages HTTP/HTTPS traffic with advanced session and transaction control.

Benefits

• Performance Optimization: Reduces server load and improves response times through intelligent caching.
• Cost Efficiency: Minimizes bandwidth consumption and infrastructure costs.
• Flexibility: Suitable for a wide range of use cases from small websites to large CDNs.
• Reliability: Proven in production environments, including Yahoo!’s infrastructure handling over 400TB daily.
• Community Support: Backed by an active open-source community and extensive documentation.
