The most common HTTP status codes
The HTTP GET command is used to request web pages from a server. The server responds with the requested document, preceded by a header. This header contains a status code, which is a 3 digit number which describes the request status.
An example of the first piece of the HTTP header when the browser uses the GET command to request Dribbit.eu:
Remote Address:220.127.116.11:80 Request URL:http://dribbit.eu/ Request Method:GET Status Code:200 OK
Statusses are divided into 5 subtypes:
4xx Client error
5xx Server error
Some of the most common HTTP status codes:
|500||Internal server error|
More information about the HTTP status code definitions is found in RFC2616.
