HTTP 203 Non-Authoritative Information vs 208 Already Reported
Both HTTP 203 (Non-Authoritative Information) and 208 (Already Reported) belong to the 2xx Success category. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. Meanwhile, 208 means that used inside a DAV: propstat response element to avoid enumerating internal members of multiple bindings to the same collection repeatedly.
