A log of the storefront's 404s and a 301 redirect for each in one click: for a store after a migration, a new URL structure or products taken off the catalog. The suggested target comes from the catalog; the redirect is a Magento URL rewrite. A 404 writes one line to a file, cron folds them into the log: no database on the storefront request.
