HTTP 203 Non-Authoritative Information vs 308 Permanent Redirect

HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 308 (Permanent Redirect) is a 3xx Redirection response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 308 means that the resource has been permanently moved. Like 301, but guarantees the HTTP method will NOT be changed.
