I don't know off the top of my head, but the CMF Cache Policy Manager 
doesn't "just" work with everything.  I'd have to look and see, but 
there are expectations which must be met for it to get called and the 
headers get injected.  My last email shows another way to get a test 
header so you can see it working.  At the end of the day, the you will 
need to come up with a policy.  I typically have several policies 
defined in my caching policy manager.  Over several projects I've 
utilized the CMF CPM and the  Accelerated HTTP Cache Manager which is 
just a Zope product.
