[Catalyst] how to cache html file after processing by a template in a catalyst applicaiton

[Sai Tong]

Hi,

  What would be the best way to cache the view ouput of catalyst before 
the output is sent from the webserver to the browser?
I am using template toolkit as the view component of a catalyst web 
application and want to save a static html file  for each response generated
after processing by the template, in addition to sending the html file 
to the browser.
