In which cases does the server not return a response body?

The server does not return a response body in the following cases:

• For responses with status codes that, according to the HTTP standard, should not contain a body, such as:

  • 1xx (informational responses)
  • 204 No Content
  • 304 Not Modified

• When a request is successfully processed and a body is not required (for example, a DELETE request may return 204 without a body).

• If the server decides not to send a body for other reasons, such as errors or restrictions.

Thus, the absence of a response body is normal behavior for certain status codes and situations.
