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 '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.

The HTTP status code '403' indicates that the server understands the request but refuses to authorize it. This typically happens when the client lacks proper permissions to access the resource, even with valid authentication. For example, trying to access an admin-only page without the necessary privileges will result in a 403 error. Unlike 401, which indicates missing or invalid authentication, 403 means the server is actively denying access.
