HTTP Status Codes

HTTP Status Codes are standardized three-digit numbers returned by a web server to indicate the result of a client’s request. Introduced with the HTTP/1.0 specification in 1996, they categorize responses into five classes: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client error), and 5xx (server error). For example, 200 OK signals a successful request, 404 Not Found indicates a missing resource, and 500 Internal Server Error reflects server-side failure.
