What are the best practices for caching in MVC applications?

Caching in MVC applications can significantly improve performance. Some best practices include using output caching, data caching, and ensuring cache invalidation.

Can you explain output caching and how to implement it?

Output caching stores the dynamic output of a controller action. You can implement it using the [OutputCache] attribute in your controller.

What about data caching? How is it different from output caching?

Data caching stores data objects rather than the output of a view. It's useful for frequently accessed data that doesn't change often.

How do I handle cache invalidation effectively?

Cache invalidation can be handled by setting appropriate expiration times, using cache dependencies, or implementing a cache busting strategy.
