What are some effective caching techniques in ASP.NET MVC?

In ASP.NET MVC, you can use several caching techniques such as Output Caching, Data Caching, and Application Caching. Output Caching stores the rendered HTML of a view, while Data Caching stores data objects in memory for quick access.

Can you explain how Output Caching works?

Output Caching works by storing the output of a controller action for a specified duration. When the same action is requested again within that duration, the cached output is returned instead of executing the action again, improving performance.

What are the benefits of using Data Caching?

Data Caching reduces database load by storing frequently accessed data in memory. This leads to faster data retrieval and improved application performance.

Are there any downsides to caching?

Yes, caching can lead to stale data if not managed properly. It's important to implement cache expiration and invalidation strategies to ensure data consistency.
