Secure applications disable browser history and internal cache. Unfortunately, this causes problems with most browsers when following the standard Rails pattern for displaying errors. For full protection from ERR_CACHE_MISS (in Chrome with no-cache, no-store), and equivalent in other browsers, the pattern should be altered to follow a full POST-REDIRECT-GET patten. This way the browser will always have a consistent back-button history to traverse without triggering browser errors.

A "Productized Rails Application" is a single generic application having a hierarchical structure wherein add-ons and tweaks for concurrent versions of the application are possible without affecting the core "generic" code base. You might use this, for example, if you want to maintain a common shopping cart code base that all of your clients use, while still providing flexibility for paid add-ons or site-specific needs.
