asset_host parallel cdn

	#To really juice up the load times of your site, configure four subdomains for your assets,
	#numbered from 0 to 3, e.g. #assets0.myapp.com to assets3.myapp.com, pointing at your asset CDN and set the following in your
	#production configuration:
	config.action_controller.asset_host = "assets%d.myapp.com"
	#Rails will cycle through each of these subdomains when it generates asset links. Browsers are generally restricted to
	#only two concurrent requests per host name, so having assets served from four allows the browser to make eight
	#concurrent requests. Page load speeds will now be constrained only by the speed of your user’s connection.#
	#If you user has a good connection then they will be able to download most of your assets in parallel.
