Headers Status Code 3-digit integer result code definitions

Hypertext Transfer Protocol -- HTTP/1.1

The first digit of the Status-Code defines the class of response. 
The last two digits do not have any categorization role. 
There are 5 values for the first digit: 

1xx: Informational - Request received, continuing process

2xx: Success - The action was successfully received,
       understood, and accepted

3xx: Redirection - Further action must be taken in order to
        complete the request

4xx: Client Error - The request contains bad syntax or cannot
        be fulfilled

5xx: Server Error - The server failed to fulfill an apparently
        valid request
