-# OutputCompression
-# Rails output compression filters
-#
-# Adds two classmethods to ActionController that can be used as after-filters:
-# strip_whitespace and compress_output.
-# If you use page-caching, you MUST specify the compress_output filter AFTER
-# caches_page, otherwise the compressed data will be cached instead of the HTML
-#
-# class MyController < ApplicationController
-#  after_filter :strip_whitespace
-#  caches_page :index
-#  after_filter :compress_output
-# end
