I have some redirects for URLs that are no longer valid so I need them to return a 410. Because the URLs are from an older version of the website (with a completely different system) I simply put them in the redirects app for easier editing. However a 410 "redirect" doesn't return anything else than the status code - the page normally shown is just empty.
How can I display something meaningful to the user (like "page no longer exists")? It would be nice to have some kind of template similar to the template for 404 errors.
Any ideas?
