Plugin Reference

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 consistent C API, everyone can implement their own functionality, without having to touch the core.

Stable plugins

Plugins that are considered stable are installed by default in Apache Traffic Server releases.
