Frequently Asked Questions

What do HTTP status code categories mean?

1xx: Informational, 2xx: Success, 3xx: Redirection, 4xx: Client Error, 5xx: Server Error. The first digit tells you the general type of response.

HTTP 418 is an April Fools joke from RFC 2324 (Hyper Text Coffee Pot Control Protocol). It is defined as the response when trying to brew coffee with a teapot.

What are HTTP status codes?

HTTP status codes are three-digit numbers returned by servers to indicate the result of a request. They are grouped into 5 classes: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client error), and 5xx (server error).
