Ultimate ASP.NET 5 Web API Development Guide - Implementing Caching

The video tutorial explains response caching, focusing on its implementation in .NET Core. It discusses the pros and cons of software-level caching versus network-level caching, highlighting the impact on server load and memory usage. The tutorial provides a step-by-step guide to configuring response caching in the program.cs file, including setting cache control headers. It concludes with a demonstration using Postman to test caching, showing how cached responses improve API performance by reducing database load.

What is a primary advantage of response caching at the software level?

• It reduces the load on the server.

• It eliminates the need for a database.

• It requires no configuration.

• It increases the server's memory usage.

In the configuration of response caching, what does setting a maximum body size determine?

• The maximum number of users accessing the API.

• The maximum number of requests the server can handle.

• The largest cacheable data size in bytes.

• The minimum response time for requests.

What does the 'use case sensitive paths' option do in response caching?

• It ignores case differences in request paths.

• It caches all requests regardless of case.

• It differentiates cache based on the case of the request path.

• It allows caching of only uppercase requests.

What is the purpose of the 'vary' header in response caching?

• To cache only JSON responses.

• To ensure all responses are cached equally.

• To vary the cache response based on another header.

• To prevent caching of compressed files.

How often does the cache refresh in the given middleware example?

• Every 60 seconds

• Every 30 seconds

• Every 10 seconds

• Every 5 seconds

What tool is used to test the caching implementation in the video?

• Fiddler

• Swagger

• Postman

• Visual Studio

What happens when a new country is added during the caching test?

• The new country appears after the cache refreshes.

• The server crashes.

• The new country appears immediately.

• The cache is cleared automatically.
