Thanks for the question, Brad. :) If by framework you mean something like ehCache versus memcached, then yes. It's always CacheBox that's ultimately managing everything, but you can change the storage engine and eviction policies of different cache stores while the app is running. So for example, you've got several different cache stores, some of them are in-memory, some are using ehCache, some are using memcached. You can selectively swap any single store (I've been calling them "agents") to a different storage engine at any given time, so you could say move the storage of one particular set of content from a database to memcached or vice versa at run-time without any problems. Or you could change the eviction policy of an agent from 10-minutes idle to 100 items first-in-first-out or something else. Most (although I'm not sure it's all) of the previous options for CF didn't allow you to make changes to the cache configuration at run-time, they depend upon the cache config occurring just once at startup. There are a couple of advantages to being able to swap things at run-time, one of them being that the service can automate changes to the eviction policies so that the cache can optimize itself in a hands-free, hassle-free way. So basically, it's cache that configures itself so that you don't have to -- and it can do a better, more efficient job of configurating itself than most of us will when we hand-code it. I know for myself when I'm thinking about configuring something in cache, I'm really guessing about the usage patterns of my data. I don't have actual usage graphs or anything to show me how long the average piece of content stays in active use, etc. But the service will have direct access to that kind of data, so it can make those decisions more accurately at run-time than I will during development. :) There are also stand-alone / portable implications as well, but those aren't my reasons for describing it as "hot swappable". Anyway, great question.
