HTTP 302 Found vs 504 Gateway Timeout

HTTP 302 (Found) is a 3xx Redirection response, while 504 (Gateway Timeout) is a 5xx Server Error response. 302 indicates that the resource temporarily resides at a different URL. The client should continue using the original URL for future requests. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
