37signals-caching

What problem does it solve?

Implements aggressive caching strategies in Rails applications to dramatically reduce response times, minimize database load, and improve user experience by leveraging HTTP caching, fragment caching, Russian doll caching, and a database-backed Solid Cache in production.

Core Features & Use Cases

• HTTP caching with ETags and conditional GET for free 304 responses
• Russian doll (nested) fragment caching with automatic invalidation via touch: true
• Fragment caching in views with cache keys tied to updated_at timestamps
• Collection caching and advanced cache_key_with_version strategies
• Low-level Rails.cache.fetch usage for expensive computations
• Solid Cache integration for database-backed caching in production
• Clear cache invalidation patterns and sweepers for complex dependencies

Quick Start

Configure a Rails app to cache aggressively using HTTP ETags, Russian doll and fragment caching, with Solid Cache in production and proper invalidation.
