Which statement about sending data in requests is true?

• A. The request body is used only for GET operations.
• B. The request body must be included in every request.
• C. The request body is limited to small data and should be avoided for complex structures.
• D. The request body can hold large or sensitive data and is sent with POST or PUT.

Answer: (D)

The request body is the payload you send to the server to create or update a resource, or to perform an operation that requires data. In practice, GET requests typically don’t carry a body; data for retrieval is usually placed in the URL query string. For actions that involve sending data to be processed, you use a request body, with POST and PUT being the common methods for this purpose. The body can contain large amounts of data and, when transmitted over HTTPS, can be sensitive while still being protected in transit. There are still practical limits on how much data you can send, imposed by servers and intermediaries, but the body itself is not restricted to small data, and it is not required for every request. That’s why the statement that the request body can hold large or sensitive data and is sent with POST or PUT is the best description of how data is typically transmitted in requests.
