http://redmine.ruby-lang.org/issues/show/4101

Author: Rodrigo Pestana
Status: Open, Priority: Normal
Target version: 1.9.2
ruby -v: ruby 1.9.2p0 (2010-08-18 revision 29036) [i386-darwin9.8.0]

I was following the screencast http://railscasts.com/episodes/93-action-caching 

In my controller
caches_action :index, :cache_path => :index_cache_path.to_proc
def index_cache_path
      if user_signed_in?
        "users/pages"
      elsif admin_signed_in?
        "admin/pages"
      else
        "public/pages"
      end
    end
