Ultimate ASP.NET 5 Web API Development Guide - CORS Configuration

The video tutorial introduces Cross-Origin Resource Sharing (CORS) and its significance in enabling APIs to be accessed by clients on different servers. It guides viewers through implementing CORS in a program by modifying the program.cs file, adding a policy named 'allow all' to permit any header, origin, and method. The tutorial emphasizes the importance of configuring CORS for third-party access and demonstrates how to apply the policy in the application pipeline.

What does CORS stand for in the context of API development?

• Cross-Origin Request Service

• Cross-Origin Resource Sharing

• Cross-Origin Request Sharing

• Cross-Origin Resource Service

Why is CORS important for APIs intended for third-party access?

• It enhances the speed of API responses.

• It restricts API access to specific IP addresses.

• It allows APIs to be accessed only by local clients.

• It enables APIs to be accessed by clients on different servers.

What is the purpose of the 'allow all' policy in CORS configuration?

• To enable access only from trusted domains

• To block all external access

• To allow access from any origin and method

• To restrict access to specific headers

How can you apply a CORS policy in the API pipeline?

• By configuring the server firewall

• By changing the client-side code

• By modifying the database settings

• By using the 'app.useCORS' method with the policy name

What is the main benefit of applying a CORS policy in an API?

• It improves the API's performance.

• It allows the API to be accessed from different machines.

• It reduces the API's security risks.

• It simplifies the API's code structure.
