Even a bit more OT: one thing to watch out for, especially if you plan on caching a *lot* of data, is that the Cache::* modules did not do collision detection on MD5 collisions the last time I looked. Forgive me if that's changed recently. The probability is extremely low, but they can and do occur "in the wild" (I won't bring anyone's name up here :). In other words, it's a remote possibility that one URI might serve up another's content if the two hash keys map to the same MD5 value. Given an infinite number of web monkeys using Cache::* and an infinite number of user monkeys clicking on links... - Barrie
