[Radiant] caching

[Todd McGrath]

Hi,

In production mode, Radiant uses page level caching right?  

Settings (environment.rb and environments/production.rb) look like page level
caching, but I thought page level caching wrote files to the public/ directory?
 I'm confused on the pages being cached as .yml in the cache/ directory?

I sincerely apologize if the answers are found someplace obvious.  I've tried
searching the past mailing lists and site.  I'm not sure, but maybe this is
related to:
