HTTP 100 Continue vs 423 Locked
HTTP 100 (Continue) is a 1xx Informational response, while 423 (Locked) is a 4xx Client Error 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, 423 means that the resource is locked and cannot be modified (WebDAV).
