Ruby method that creates and imports a web font. Preferably used in an .css.scss.erb file to download the css for a Google Font statically. This saves an http request during page load.

webfont.erb

<%
require 'net/http'
def require_web_font(o={})
  o = {:family=>"Open Sans",:weights=>["500","500italic"],:url=>"http://fonts.googleapis.com/css"}.merge(o)
  url = URI.parse(URI::encode("#{o[:url]}?family=#{o[:family]}:#{o[:weights] * ','}"))
  Net::HTTP.start(url.host,url.port){|http| http.request(Net::HTTP::Get.new(url.to_s))}.body
end
%>

<%= require_web_font({  :family => "Droid Sans",
                        :weights => [
                                "300",
                                "300italic",
                                "400",

                                "500italic",
                                "700",
