HTTP response status codes

HTTP response status codes indicate the outcome of an HTTP request. They range from informational 1xx, success 2xx, redirection 3xx, client error 4xx, to server error 5xx. For example, 200 signifies success, 404 indicates not found, and 500 suggests a server error. Understanding these codes aids in troubleshooting and debugging web applications.
