HTTP 102 (Processing) is a 1xx Informational response, while 407 (Proxy Authentication Required) is a 4xx Client Error response. 102 indicates that the server has received and is processing the request, but no response is available yet. Prevents the client from timing out. In contrast, 407 means that the client must first authenticate itself with the proxy.
