What is the difference between output cache and data cache in MVC?

Output cache stores the rendered HTML of a view, while data cache stores data objects. Output cache improves response time for static content, whereas data cache is useful for frequently accessed data.

Can you give me an example of when to use each?

Sure! Use output cache for pages that don't change often, like a product page. Use data cache for data that changes frequently but is expensive to retrieve, like user profiles.

What are the performance implications of using each?

Output caching can significantly reduce server load and response time for static content. Data caching can speed up data retrieval but requires careful management to ensure data consistency.

Are there any downsides to using caching?

Yes, caching can lead to stale data if not managed properly. It also adds complexity to your application, as you need to handle cache invalidation.
