HTTP 101 Switching Protocols vs 307 Temporary Redirect
HTTP 101 (Switching Protocols) is a 1xx Informational response, while 307 (Temporary Redirect) is a 3xx Redirection response. 101 indicates that the server understands the Upgrade header field request and indicates which protocol it is switching to. In contrast, 307 means that the resource temporarily resides at a different URL. Unlike 302, this guarantees the HTTP method will NOT be changed.
