HTTP 100 Continue vs 206 Partial Content
HTTP 100 (Continue) is a 1xx Informational response, while 206 (Partial Content) 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, 206 means that the server is delivering only part of the resource due to a Range header sent by the client. Used for resumable downloads and video streaming.
