What are the different types of caching in Rails?

In Rails, there are several types of caching: page caching, action caching, fragment caching, and low-level caching.

Can you explain page caching and how it works?

Page caching stores the entire output of a controller action, serving it directly for subsequent requests without hitting the application.

What about fragment caching? How is it different?

Fragment caching allows you to cache specific parts of a view, rather than the whole page, which is useful for dynamic content.

Are there any best practices for using caching in Rails?

Yes, it's best to cache only what is necessary, monitor cache performance, and invalidate caches appropriately to avoid stale data.
