HTTP 100 Continue vs 418 I'm a Teapot
HTTP 100 (Continue) is a 1xx Informational response, while 418 (I'm a Teapot) is a 4xx Client Error response. 100 indicates that the server has received the request headers and the client should proceed to send the request body. This lets the client know it can continue with the request or abort if the headers were rejected. In contrast, 418 means that any attempt to brew coffee with a teapot should result in this error. An April Fools' joke from 1998 that became a beloved part of HTTP culture.
