HTTP 100 Continue vs 407 Proxy Authentication Required
HTTP 100 (Continue) is a 1xx Informational response, while 407 (Proxy Authentication Required) 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, 407 means that the client must first authenticate itself with the proxy.
