Padrino still doesn't support those out of the box. That is the intent of the padrino-cache gem which hasn't been fleshed out yet. It is the last major set of functionality that needs to be sorted out. In the meantime, the sinatra-cache from here:
seems to provide most of the needed functionality for now and since Padrino supports all rack / sinatra based extensions, it is a reasonable alternative until we finish integrated caching.
Fair enough. I can't blame you I want this functionality built into Padrino too and I am one of the core developers. I just haven't had the time to do it right yet and this is a piece that I want to be particularly easy to use and well-done.
