Learning ASP.NET Web API (Video 18)

This video tutorial covers the implementation of paging in an application. It explains the importance of paging to efficiently handle large data sets by returning only a subset of items to the client. The tutorial demonstrates how to implement paging using page number and page size parameters, and how to add metadata such as total item count and page links. It also discusses the placement of metadata in the response header and validates the implementation using Postman. Additionally, the video introduces the concept of a maximum page size to prevent excessive data retrieval.

Why is it not advisable to return thousands of items to a client in one go?

• It is against data privacy regulations.

• It can overwhelm the client application.

• It increases the server load.

• It is not supported by most APIs.

What are the two main parameters required to implement paging?

Where is it suggested to include paging metadata in the response?

• In a separate metadata file

• In the URL parameters

• In the page header

• In the response body

What is the purpose of introducing a maximum page size?

• To enhance data security

• To prevent excessive data retrieval

• To improve server uptime

• To limit the number of API calls

What happens if the requested page size exceeds the maximum allowed page size?

• The request is denied.

• The page size is reset to the maximum allowed size.
