Apache Traffic Server is a fast, modular, scalable and extensible HTTP/1.1 compliant caching proxy server. It speeds internet access, enhances the performance of a website, as well as delivering web hosting capabilities.
This software is a high-performance building block for cloud services. It is more than just a caching proxy server, as it also has support for plugins to build large scale web applications.
Traffic Server is designed to improve content delivery for enterprises, Internet service providers (ISPs), backbone providers, and large intranets by maximizing existing and available bandwidth. Traffic Server was formerly a commercial product created by Inktomi and later aquired by Yahoo! in 2002. Yahoo! maintained the source until its open source release in August 2009.
Features include:
- Proxying:
- Receives user requests for web content as those requests travel to the destined web server (origin server). If Traffic Server contains the requested content, then it serves the content directly. If the requested content is not available from cache, then Traffic Server acts as a proxy.
- provides explicit proxy caching, in which the user’s client software must be configured to send requests directly to Traffic Server.
- Caching.
- Reverse proxy.
- Participate in flexible cache hierarchies, in which Internet requests not fulfilled from one cache are routed to other regional caches, thereby leveraging the contents and proximity of nearby caches.
- Supports ICP (Internet Cache Protocol) peering.
- Network traffic analysis and monitoring:
- Traffic Line and Traffic Shell to collect and process statistics obtained from network traffic information.
- Transaction logging.
- Security:
- Control client access to the Traffic Server proxy cache.
- Configure Traffic Server to use multiple DNS servers to match your site’s security configuration. For example, Traffic Server can use different DNS servers, depending on whether it needs to resolve hostnames located inside or outside a firewall. This enables you to keep your internal network configuration secure while continuing to provide transparent access to external sites on the Internet.
- Configure Traffic Server to verify that clients are authenticated before they can access content from the Traffic Server cache.
- Secure connections in reverse proxy mode between a client and Traffic Server, and Traffic Server and the origin server, using the SSL termination option.
- Control access via SSL (Secure Sockets Layer).
- Scales well on modern SMP hardware, handling 10s of thousands of requests per second.
- APIs to write your own plug-ins to do anything from modifying HTTP headers to handling ESI requests to writing your own cache algorithm.
