In this blog post, I want to dive into the Shopware Caching to clarify how it works and what you have to care about while developing features. We will go from the inner to the outer caching layer in multiple steps and look into them independently.
Stage one - the object cache First, we will start with the object cache implemented in serval “route” classes. The “route” classes/controllers are always used in the Shopware context as an entry point for the store-API.

Explores Shopware 6's multi-layered caching architecture, from object cache in route classes to HTTP cache and reverse proxy integration. Covers cache key generation, invalidation strategies using tags, state-based cache skipping for logged-in users and filled carts, and configuration for external reverse proxies like Varnish. Details CSRF handling in cached responses and provides VCL configuration examples for maximizing cache hit rates.
