Which of the following HTTP methods is NOT commonly supported by REST?

• A. GET
• B. SEND
• C. PUT
• D. DELETE

Answer: (B)

In RESTful services, the commonly used HTTP methods include GET, PUT, DELETE, and POST. Each of these methods serves a distinct purpose within the context of REST. For instance, GET is used to retrieve data, PUT is utilized for updating existing data, DELETE is for removing resources, and POST is for creating new resources.

The method SEND is not standardized in the HTTP specification and is not recognized as a core HTTP method used in RESTful APIs. Therefore, it is not commonly supported or used in REST architectures. By only utilizing recognized methods like GET, PUT, and DELETE, REST ensures uniformity and interoperability across different web services. This adherence to standard methods helps developers and applications communicate effectively without ambiguity.

Understanding the functionality and purpose of standard HTTP methods is essential for working with RESTful APIs, as it forms the foundation of how clients and servers interact and manage resources over the web.
