Hi,

here is a shorter version ;-)

require "net/http"
require "cgi"

class ShortURL
    def self.web(server, action, code)
       Net::HTTP.start(server, 80) { |http|
          response = http.instance_eval action
          response.code == code ? yield(response.read_body) : nil
       }
    end

    def self.rubyurl(url)
       web("rubyurl.com",'get("/rubyurl/create?rubyurl[website_url]='+CGI.escape(url)+'")',"302")  
{ |body|
          /<a href="(.+)">/.match(body)[1]
       }
    end

    def self.tinyurl(url)
       web("tinyurl.com",'post("/create.php", "url='+url+'")',"200")  
{ |body|
          /hidden name=tinyurl value="(.+)"/.match(body)[1]
       }
    end
end
