Rails - Jun 2012 - does expires_in store data in server cache or is it client only?

Hi,

I''m having an issue with expires_in. From the docs 
(http://apidock.com/rails/ActionController/ConditionalGet/expires_in) it 
looks like it should only set a header.  However, with a simple test 
application I can see it storing data to cache.

class HomeController < ApplicationController
  def index
    expires_in 5.minutes, :public => true
  end
end

Results in a file 
like tmp/cache/AE9/880/f812f291251bb669867bae9c9d030ab7b4c0bd20 which 
contains the page body.  I can modify that file and see it being sent back 
to the client.

I''m surprised to see it storing data on the server - I thought it would
just send a header.  I also see no way of invalidating the cache.  In the 
example above the data is cached for 5 minutes and no amount of refreshing 
or shift-refresh shift-ctr-refresh etc. which is supposed to ignore client 
caching seems to reset it.  Should it be caching like this and if so can I 
invalidate it?
