1×× Informational

100 Continue

HTTP 100 Continue is a informational-class status code defined in RFC9110. The server received the request headers; the client should proceed to send the body.

Informational responses tell the client the request was received and the conversation continues — they are interim, never final. On the wire, the response begins with the status line HTTP/1.1 100 Continue.
