Thanks for the response, Anthony. Yes, these are AJAX components. I've been toying with different ways of structuring my app. In one case, I have a top level controller function that passes some db results down to a bunch of views. But some of the views have evolved to have components that also need the db query results, which has triggered a rewrite.
I've renormalized code so that there's no duplicated effort in querying the db, but it raised the question of whether a top-level function could pass a db Storage object down to a lower-level component, rather than having the component's controller function do the query. The latter case has the potential of duplicating queries unless one is careful to partition functionality. I hadn't thought of using the cache. In my case, I'm not sure it'll work since the db is highly dynamic. Sessions won't work either, since I was interested in passing a db Storage object, not just an index. Since I can't figure out how to pass Storage objects, I'm gravitating towards passing indices instead. I figured I would put this all in a thread since it seems like something that might affect other people, too. Thanks again for your thoughts on the subject.
