HTTP 200 OK vs 203 Non-Authoritative Information
Both HTTP 200 (OK) and 203 (Non-Authoritative Information) belong to the 2xx Success category. 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. Meanwhile, 203 means that the response payload has been modified by a transforming proxy from the origin server's 200 response.
