Apache Traffic Server is a fast, scalable, and extensible HTTP/1.1 and HTTP/2 compliant caching proxy server written in C++. It powers major CDNs and content providers, serving multiple terabits per second of traffic, and supports plugins for building large-scale web applications.

Use cases

• set up a caching reverse proxy for a website
• run a forward proxy with content filtering
• build a CDN edge cache server
• add load balancing and keep-alive to backend services
• cache frequently requested web pages and API responses
• proxy HTTP/2 and HTTP/3 traffic at scale
• write custom plugins to modify HTTP headers or cache behavior

When to choose

• you need a battle-tested, high-performance caching proxy that scales to terabits per second
• you want an extensible proxy with a plugin API for custom request handling
• you are building CDN or large-scale cloud infrastructure
• you need HTTP/1.1, HTTP/2, and emerging protocol support in a self-hosted proxy

When to avoid

• you need a simple lightweight reverse proxy with minimal configuration (nginx or Caddy may suffice)
• you only need TLS termination or static file serving
• you lack operations capacity to tune and maintain a complex proxy deployment
