Yes, I have to admit I was a little surprised that application scope data couldn't replicate the same way session scope data can. As you say tho', it depends on the underlying J2EE model which doesn't have a way to support this. > I imagine that an elegant solution might be achieved with JMS? but > have no > experience of using this with CF. Yes, we actually experimented with that, using JMS to send change notification messages and having a subscriber process on each server perform the updates. We were doing it for server scope cached data but the same principle applies to application scope. I say experimented with because we didn't implement it in the end - a lot of work and complexity. Most of our cached data changes infrequently and under external (human) control so we just added a cache refresh as part of the manual data update process.
