[Zope] Zope and remote caches.

So, if I am grokking the whole zope thang properly here, then theoretically, when I imbed objects within my zope documents, I shouldn't hardcode in specific urls to them. Instead, I should treat them almost as if they are always in the current directory, even if they are a couple of folders up. This way, if I want to override some behavior in the future, I just copy the object down into the current folder and edit it. I notice however, that if I do this, it plays hell with browser caching because the browser winds up pulling things from different places all the time even if it's actually winding up pulling the same document down. How do other people deal with this? -- Fundamentally, there may be no basis for anything.
