HTTP 101 Switching Protocols vs 407 Proxy Authentication Required

HTTP 101 (Switching Protocols) is a 1xx Informational response, while 407 (Proxy Authentication Required) is a 4xx Client Error response. 101 indicates that the server understands the Upgrade header field request and indicates which protocol it is switching to. In contrast, 407 means that the client must first authenticate itself with the proxy.
