Not sure; I typically script all my builds, so I do it manually.  In 
your CMF instance, it will be in the ZMI product pull-down:   "CMF 
Caching Policy Manager"

Good question :)  I don't know....  For a test, you can setup a  Policy 
as follows:

Policy ID:  default
Predicate: python:None
Max age: 300  <-- 5 minutes


Check the 'Must-Revalidate' box.

Depending on your expectations and needs, it could get complex setting 
up policies.
