What are HTTP Status Codes?
HTTP status codes are 3-digit numbers returned by a server in response to a client's request. They indicate whether the request was successful, requires action, or encountered an error. Codes are grouped into five classes: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client errors), and 5xx (server errors).
