     # By default, Rails links to these assets on the current host in the public
-    # folder, but you can direct Rails to link to assets from a dedicated assets server by
-    # setting ActionController::Base.asset_host in your <tt>config/environment.rb</tt>.  For example,

+    # For example, you'd define <tt>assets.example.com</tt> to be your asset

     #   ActionController::Base.asset_host = "assets.example.com"

-    # This is useful since browsers typically open at most two connections to a single host,
-    # which means your assets often wait in single file for their turn to load.  You can
-    # alleviate this by using a <tt>%d</tt> wildcard in <tt>asset_host</tt> (for example, "assets%d.example.com")
-    # to automatically distribute asset requests among four hosts (e.g., "assets0.example.com" through "assets3.example.com")
-    # so browsers will open eight connections rather than two.
