HTTP 203 Non-Authoritative Information vs 204 No Content
Both HTTP 203 (Non-Authoritative Information) and 204 (No Content) belong to the 2xx Success category. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. Meanwhile, 204 means that the server successfully processed the request but is not returning any content. Common for DELETE operations and form submissions that don't need a response body.
