Learning ASP.NET Web API (Video 36)

The video tutorial covers caching and versioning in an MVC client for a bookstore API. It begins with an introduction to HTTP caching, explaining how to implement it using E tags and temp data. The tutorial then explores different versioning strategies, including using headers and custom header names. The video concludes with a summary and a preview of the next section, which will discuss best practices for Web API implementation.

What is the primary benefit of using HTTP caching in a thick client?

• It reduces server load by storing responses locally.

• It increases the complexity of the client application.

• It requires frequent updates to the client code.

• It is only useful for server-based applications.

How does the MVC client determine if cached data should be used?

• By verifying the client's IP address.

• By comparing the ETag header with the stored value.

• By checking the response size.

• By analyzing the request method.

Which versioning approach allows changing the API version without modifying the code?

• Using a custom header name.

• Embedding version in the URL path.

• Reading version from a configuration file.

• Appending version to query parameters.

What is a potential advantage of using a custom header for API versioning?

• It eliminates the need for client-side caching.

• It allows for more flexible version management.

• It requires less server-side processing.

• It simplifies the URL structure.
