No. There is no need to do so. The correct response at the final URL is sufficent.
The redirect response could return a human-readable HTML page like:
<body><p>This page has moved. It's now located at <a href="www.example.com/somepage">www.example.com/somepage</a></p></body></html>
In that case, the page IS text/html.
