HTTP 100 Continue vs 424 Failed Dependency

HTTP 100 (Continue) is a 1xx Informational response, while 424 (Failed Dependency) 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, 424 means that the request failed because it depended on another request that failed (WebDAV).
