HTTP Response Code

HTTP response code is the number code that a server sends back to the browser in response to an HTTP request. The purpose of this code is to indicate whether or not the request was successful. There are five main classes of HTTP response codes, each with a different meaning:

1xx - Informational: These status codes indicate a provisional response. The client should continue with its request.

2xx - Success: These status codes indicate that the request was successful and that the requested information has been sent back to the client.

3xx - Redirection: These status codes indicate that the client must take additional action in order to complete their request.

4xx - Client Error: These status codes indicate that there was an error with the request made by the client.

5xx - Server Error: These status codes indicate that there was an error with the server and that the server could not fulfill the request.
