HTTP Response Status Code Groups
The response status codes are grouped according to the result. The group is determined by the first digit of the code number. Let's examine these groups:
| Group | Description |
|---|---|
1xx |
Codes starting with 1 are informational messages from the server about the data transfer process.
|
2xx |
Codes starting with 2 represent success messages.
|
3xx |
Codes starting with 3 tell the client that another request must be made to a different URI to successfully complete the operation. That is, the server with such a response code forces the browser to perform a redirect to another address.
|
4xx |
Codes starting with 4 indicate that the server has encountered an error due to the client's fault.
|
5xx |
Codes starting with 5 indicate that an error occurred on the server due to the server's fault.
