About the Book
Drupal's caching architecture spans multiple layers: render arrays in memory, cache backends in the database, HTTP headers on the response, and rules in the reverse proxy. Getting any layer wrong costs you either performance or correctness.
This book covers the full stack. You will learn how cacheable metadata flows through the render pipeline, how cache backends store and invalidate data, how HTTP response headers instruct reverse proxies, and how to write modules that participate correctly at every layer. Chapters progress from core concepts to debugging real-world cache failures and writing cacheable code from scratch.
The audience ranges from site builders who want to understand cache tags to module developers building custom cache backends. Every chapter works through real Drupal 11 APIs, grounded in code.
