Granted, but I'm not entirely sure of the connection you're trying to make.
For the most part, my dynamically generated objects don't change length or
content and it's ok to cache them. For the ones that do change every time,
I add an Expires header to the response to let know caching mechanisms now
not to cache it. Unfortunately, my tests indicate that Netscape doesn't
handle the Expires header properly :(
