Why should you care?

Production ShopNest needs more than CRUD — this is how real sites stay fast and observable.

See it live — copy this example

Create an MVC project (dotnet new mvc), add the code, and run dotnet run.

// Response Caching — ShopNest.Mvc example
public class HomeController : Controller
{
    public IActionResult Index() => View();
}

Run Example »

Edit the code and click Run — like W3Schools Try it Yourself.

What happened?

• Study the example line by line.
• Each part connects to Response Caching.
• Edit one line, save, and run dotnet run to see what changes.

Try it yourself

1. Register the service or middleware in Program.cs if needed.
2. Trigger the feature once in the browser.
3. Check logs or behavior described in the lesson.
4. Change text or labels in the example and run again — watch the browser update.
5. Break the code on purpose (remove a semicolon), read the error message, then fix it.

Remember

You learned what Response Caching is and when to use it. Practice by changing the example yourself. Explain it in your own words before moving on.
