Into which 5 groups are HTTP status codes divided?

HTTP status codes are divided into 5 main groups based on the first digit:

1. 1xx (Informational) — informational responses indicating that the request has been received and processing continues.
2. 2xx (Successful) — successful execution of the request (e.g., 200 OK).
3. 3xx (Redirection) — redirections, the client must take additional actions to complete the request.
4. 4xx (Client Error) — client errors, such as a bad request or access denial (404 Not Found, 403 Forbidden).
5. 5xx (Server Error) — server errors, when the server cannot process the request correctly (500 Internal Server Error).

Each group reflects a general response status and helps the client understand the result of the request.
