HTTP 204 No Content vs 504 Gateway Timeout
HTTP 204 (No Content) is a 2xx Success response, while 504 (Gateway Timeout) is a 5xx Server Error response. 204 indicates 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. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
