Apache Traffic Server(tm) software is a fast, scalable and extensible
HTTP/1.1 and HTTP/2 compliant caching proxy server. Formerly a
commercial product, Yahoo! donated it to the Apache Foundation, and
currently used by several major CDNs and content owners.

Overview

  * Caching

    Improve your response time, while reducing server load and
    bandwidth needs by caching and reusing frequently-requested web
    pages, images, and web service calls.

  * Proxying

    Easily add keep-alive, filter or anonymize content requests, or
    add load balancing by adding a proxy layer.

  * Fast

    Scales well on modern SMP hardware, handling 10s of thousands of
    requests per second.

  * Extensible

    APIs to write your own plug-ins to do anything from modifying
    HTTP headers to handling ESI requests to writing your own cache
    algorithm.

  * Proven

    Handling over 400TB a day at Yahoo! both as forward and reverse
    proxies, Apache Traffic Server is battle hardened. Also visit our
    Customers page for some of our corporate users and supporters.
