HTTP 100 Continue

The HTTP 100 Continue informational response status code indicates that the initial part of a request has been received and has not yet been rejected by the server.

When to use

The client should continue with a request or discard the 100 response if the request is already finished.

Examples

This status code is typically sent when a client sends a request with the Expect: 100-continue header, and the server is willing to receive the request body.
