 We don't promise that every plugin gets merged into the core. We need to keep the core as small as
 possible with only the most widely used plugins to keep it maintainable.
 
 The alternative is providing your plugins in your own repository. Please let us know when you do,
 we would like to add a list of existing third party plugins to the list of plugins.

 The ``CachePlugin`` allows you to cache responses from the server. It can use
 any PSR-6 compatible caching engine. By default, the plugin respects the cache
 control headers from the server as specified in :rfc:`7234`. It needs a
 :ref:`stream <stream-factory>` and a `PSR-6`_ implementation::
