What is an HTTP status code?
An HTTP status code is a three-digit number returned by a server in response to a client request. It indicates whether the request succeeded, failed, or needs further action. Codes in the 2xx range mean success; 4xx means client error (e.g. 404 Not Found); 5xx means server error (e.g. 500 Internal Server Error).
