What is caching? In computing, a cache is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere.

Types of caching • Response or Client Caching • OutputCache • Memory Cache • Distributed Cache using Redis • Others?

Benefits of caching • Save server roundtrips • Decrease response time • Improve performance • Save money?

Best practices • Cache early, cache often • Caches should be relatively small • Expire Cache

Let’s see some code!
