Caching stores frequently used data or information in local memory for a specific period. When a client requests the same information, instead of retrieving the information from its permanent data store, it will give the information from the local memory. The main advantage of caching is that it improves performance by reducing the processing burden.

In this talk, we will discuss and learn how to use caching in ASP.NET 9 Web API on both the server and client sides to improve its performance by decreasing the response time to the user. The talk's result will include local and distributed cloud solutions for caching and guidance on when and how to use the technique.
