The [Ramaze] flash isn't just for messages
Written on 24 Aug 2012 by Kester Dobson
Interesing piece on The Pug Automatic about creative uses for the Rails `flash` function. Although the implementations differ, the Ramaze version of `flash` will enable you to do much the same things.
A good reminder in the comments, as well, about not caching any views where you are likely to be using this, as people will either end up with other people's flashes, or stuck with the same flash for X minutes/hours.
