HTTP 200 OK vs 504 Gateway Timeout
HTTP 200 (OK) is a 2xx Success response, while 504 (Gateway Timeout) is a 5xx Server Error response. 200 indicates that the request succeeded. The meaning depends on the HTTP method: GET returns the resource, POST reports the action result, HEAD returns headers only. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
