Epic! Lemmih and I have talked about doing something like this in theory.
But having it in reality is much, much better :) Have you considered switching to acid-state and safecopy? Future versions of happstack will use those instead of happstack-data and happstack-state. (And, there is no reason you can not use them with Happstack 6 already). - jeremy On Mon, Aug 29, 2011 at 4:43 PM, Roman Smrž <roman.s...@seznam.cz> wrote: > The package swapper provides a wrapper for functors, which allows their > data to be automatically and transparently swapped to disk and loaded > back when necessary.
