HTTP 403 Forbidden vs 508 Loop Detected
HTTP 403 (Forbidden) is a 4xx Client Error response, while 508 (Loop Detected) is a 5xx Server Error response. 403 indicates that the server understood the request but refuses to authorize it. Unlike 401, authentication will not help — the user simply does not have permission. In contrast, 508 means that the server detected an infinite loop while processing the request (WebDAV).
