The HTTP status code '301' indicates that the requested resource has been permanently moved to a new URL, and future requests should use the new location. For example, a web page that was previously 'www.example.com/example-1', being moved to ''www.example.com/example-2' would require a 301 redirect so anytime a user tries to go to 'www.example.com/example-1', they are instantly redirected to the new location.

The HTTP status code '204' indicates that the server successfully processed the request but did not return any content in the response. This is commonly used in APIs when the operation is successful but there is no need to return data. For example, a DELETE request may return 204 to confirm that the resource was successfully removed without sending additional information.

The HTTP status code '302' indicates that the requested resource has temporarily moved to a different URL. Unlike 301 (permanent redirect), the client should continue using the original URL for future requests. This status code is often used for temporary redirects, such as when a website redirects users to a maintenance page or a login screen before returning them to the original destination.
