What’s the best way to handle url slugs that change? For example, if I have www.example.com/page/foo, and the user changes that page’s title to bar, the slug updates to www.example.com/page/bar and anyone visiting the old url gets automatically redirected to the new one. But now the old slug of foo can’t be used again (without appending some unique identifier to it, like foo-th683gh9i).
It’s not great but it matters less when the content you get going to that page is so unremarkable. Don’t forget you can do that to any url, even of sites that don’t use optional slugs, if your goal is just vague, evil-by-link-appearance.
