Cachedwithin does load the dataset into server memory but stays there until it times out, and then refreshes. Setting it in the application scope requires you to query the database for the data to put into that scope and store it on every request. That is my understanding.

I saw this technique used several times, and prefered over the cachedWithin method. Apparently it's easier to control, to flush the cache, and I guess you could use Cfqueryparam as well. > But again, I'm quite confused with the two methods, as both are loaded in the memory anyway.. > I guess if cachedWithin is here, it's probably for a good reason. > > Thanks again Doug :) > > > > > >Paul, > > > >You should never store database information into a memory variable unless it > >is within your shopping cart and then I would store it as a array.
