Introduction
------------

[](#introduction)

Symfony's `HttpCache` store implementation is rather old and was developed when there were no separate components for locking and caching yet. Moreover, expired cache entries are never pruned and thus causes your cache directory to continue to grow forever until you delete it manually.

Along the way, I needed support for cache invalidation based on tags which was pretty easy to implement thanks to the Symfony Cache component.

This bundle thus provides an alternative `StoreInterface` implementation that…

- …instead of re-implementing locking and caching mechanisms again, uses the well tested Symfony Cache and Lock components, both with the local filesystem adapters by default.
- …thanks to the `TagAwareAdapterInterface` of the Cache component, supports tag based cache invalidation.
- …thanks to the `PrunableInterface` of the Cache component, supports auto-pruning of expired entries on the filesystem trying to prevent flooding the filesystem.
- …allows you to use a different PSR-6 cache adapters as well as a different lock adapter than the local filesystem ones. However, **be careful about choosing the right adapters**, see warning below.
- …supports `BinaryFileResponse` instances.

Installation
