What is caching in ASP.NET and how can I implement it?

Caching in ASP.NET is a technique to store frequently accessed data in memory to improve application performance. You can implement it using various caching mechanisms like in-memory caching, distributed caching, or output caching.

Can you explain the difference between in-memory caching and distributed caching?

In-memory caching stores data in the memory of the web server, making it fast but limited to that server. Distributed caching, on the other hand, stores data across multiple servers, allowing for scalability and shared access.

What are some common caching strategies I should consider?

Common caching strategies include cache-aside, write-through, and write-behind caching. Each has its use cases depending on data consistency and performance needs.

How do I clear the cache in ASP.NET?

You can clear the cache in ASP.NET by using the HttpContext.Current.Cache.Remove(key) method for specific items or HttpContext.Current.Cache.Clear() to clear all cached items.
