What are the different caching strategies in Ruby on Rails?

In Ruby on Rails, the main caching strategies include page caching, action caching, fragment caching, and low-level caching. Each serves different purposes and can be used based on your application's needs.

Can you explain page caching and how it works?

Page caching stores the entire output of a view in a file, which can be served directly without hitting the application. This is great for static content.

What about fragment caching? How is it different?

Fragment caching allows you to cache specific parts of a view, rather than the whole page. This is useful for dynamic content that changes less frequently.

Which caching strategy is the most efficient?

The efficiency of a caching strategy depends on your application's specific use case. Page caching is often the fastest, but fragment caching offers more flexibility for dynamic content.
