Caching Strategies for Rails 8

Overview

Rails provides multiple caching layers:

• HTTP caching: ETags and fresh_when for 304 Not Modified
• Fragment caching: Cache view partials
• Russian doll caching: Nested cache fragments with touch: true
• Low-level caching: Cache arbitrary data with Rails.cache.fetch
• Collection caching: Efficient cached rendering of collections
• Solid Cache: Database-backed caching (Rails 8 default, no Redis)
