HTTP 100 Continue vs 416 Range Not Satisfiable
HTTP 100 (Continue) is a 1xx Informational response, while 416 (Range Not Satisfiable) 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, 416 means that the server cannot serve the requested byte range. The Range header value is outside the resource's size.
