[Zope] Cache headers

I am trying to ensure that zope delivered content (Zope 2.7 at this point) is upstream cacheable regardless of whether the users delivered to are authenticated or not(currently my site is fronted by Cookie Crumbler based login/authentication). My understanding is that the way to do this is to create an HTTPcache object and associate all the material that should be cached with it(in addition to unchecking the "anonymous" only cache check box). Am I making a correct assumption? Is there any way to automatically force that association on all content created in a directory and subdirectories or must this association always be done by hand? Some simple call to the cache software perhaps?
