Response caching is a technique for storing the responses of an API or web application in a cache so that they can be served faster to subsequent requests. The responses are stored in a cache with a key that uniquely identifies them, and the cache has a limited size and a policy for removing items when it becomes full.

1. Improved performance by reducing the load on the server.
2. Reduced server load, as it can serve the cached response instead of generating a new one.
3. Reduced bandwidth usages it reduces the amount of data that needs to be transferred between the server and the client.
4. Improved security as it can reduce the number of requests that reach the server, reducing the risk of certain types of attacks.

1.The request must result in a server response with a 200 (OK) status code.
2.Response Caching Middleware must be placed before middleware that require caching. For more information, see ASP.NET Core Middleware.
3.The Authorization header must not be present.
4. Cache-Control header parameters must be valid, and the response must be marked public and not marked private.
5. The Content-Length header value (if set) must match the size of the response body.

In your application you can apply response caching to those requests whose response is changed after a time and you are sure about it.

Create an application apply caching and then request it from Postman and set time to 60 minutes, you will notice that only first request will reach the controller, after that even if you try request will not reach controller.
