HTTP 203 Non-Authoritative Information vs 408 Request Timeout
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 408 (Request Timeout) is a 4xx Client Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 408 means that the server timed out waiting for the request. The client did not produce a request within the time the server was prepared to wait.
