HTTP 101 Switching Protocols vs 508 Loop Detected
HTTP 101 (Switching Protocols) is a 1xx Informational response, while 508 (Loop Detected) is a 5xx Server Error response. 101 indicates that the server understands the Upgrade header field request and indicates which protocol it is switching to. In contrast, 508 means that the server detected an infinite loop while processing the request (WebDAV).
