You'll need to add a couple headers to pages you want cached,
instructing the cache as to how they should be handled.  I create a DTML
method called cache_content that consists of:

<dtml-call "RESPONSE.setHeader('Expires',
_.DateTime(_.DateTime().timeTime() + 3600).toZone('GMT').rfc822())">
<dtml-call "RESPONSE.setHeader('Last-Modified',
bobobase_modification_time().toZone('GMT').rfc822())">

And then can call that method from any page I want to be cached by
Apache.

HTH,
