HTTP 100 Continue vs 201 Created
HTTP 100 (Continue) is a 1xx Informational response, while 201 (Created) is a 2xx Success 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, 201 means that the request succeeded and a new resource was created. Typically returned after POST or PUT requests that create a new entity.
