Overview

One of the key features of Apache Traffic Server is modularity. Features that aren't needed in the core simply aren't there. This is a good thing, because it guarantees that our core can remain fast by concentrating on the things that we always provide: Caching and proxying.

All other things can be moved into plugins, by opening up a consitent C API, everyone can implement their own functionality, without having to touch the core.

Download

Apache Traffic Server Plugins considered stable are released together with the server. See bundle.

Those which haven't received enough production testing from our developers or feedback from our users to be consiered stable can still be optained seperately via git:
