HTTP 205 Reset Content vs 502 Bad Gateway
HTTP 205 (Reset Content) is a 2xx Success response, while 502 (Bad Gateway) is a 5xx Server Error response. 205 indicates that the server fulfilled the request and the client should reset the document view (e.g., clear a form). In contrast, 502 means that the server, acting as a gateway or proxy, received an invalid response from the upstream server.
