The initial part of a request has been received and has not yet been rejected by the server. The server intends to send a final response after the request has been fully received and acted upon.
When the request contains an Expect header field that includes a 100-continue expectation, the 100 response indicates that the server wishes to receive the request payload body[1](#ref-1). The client ought to continue sending the request and discard the 100 response.
If the request did not contain an Expect header field containing the 100-continue expectation, the client can simply discard this interim response.
