HTTP 102 Processing vs 401 Unauthorized

HTTP 102 (Processing) is a 1xx Informational response, while 401 (Unauthorized) 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, 401 means that the request requires user authentication. The response includes a WWW-Authenticate header indicating the authentication scheme.
