Sinatra and compass sending compressed cached CSS

I have previously mentioned on blogger how to use Compass and SASS with Sinatra for rendering the stylesheets.

I have added a few options which are not in the main tutorials. Compress the stylesheet, this removes all the white space saving bandwidth when transmitting the file.

configure do
....

  ##Compass CSS/SASS stuff below
  Compass.configuration do |config|
     config.project_path = File.dirname(__FILE__)
     config.sass_dir = 'views/stylesheets'
     config.output_style = :compressed
  end
end

The second setting is to tell browsers to cache the stylesheet so that passenger does not have to keep building the file via compass.

##CSS rendering
get '/stylesheets/:name.css' do
   content_type 'text/css', :charset => 'utf-8'
   response['Expires'] = (Time.now + 60*60*24*356*3).httpdate
   sass(:"stylesheets/#{params[:name]}" )
end
