Overview [1]#

HTTP 100 is an HTTP Status Code indicating that everything so far is OK and that the client should continue with the HTTP Request or ignore it if it is already finished.

To have a server check the HTTP Request Headers, a client MUST send Expect: 100-continue as a header in its initial HTTP Request and receive a HTTP 100 Continue status code in HTTP Response before sending the HTTP Body.
