      @content_type = 'text/plain'
      @authorization = session[:auth]
      #get_response_with_auth("http://55.7.28.210:4321/TSI-Dev/")

  end



  def get_response_with_auth(url)
      url_parsed = URI.parse(url)

      @response = Net::HTTP.start(url_parsed.host, url_parsed.port) {|http|
            @req = http.get('/', {'Authorization' => @authorization, 'Accept' => @accept})
      }
  end

end



From Gem authentication :


  def initialize_variables
    if request.env["HTTP_AUTHORIZATION"].nil?
      if APP_CONFIG['routes_login_path'].nil?
          redirect_to login_path
      else
          redirect_to APP_CONFIG['routes_login_path']
      end
    else
      if !request.env['REMOTE_USER'].nil?
        session[:user]=request.env['REMOTE_USER']
        session[:auth]=request.env["HTTP_AUTHORIZATION"]
      end
    end
  end




In the application controller i use :

 def is_logged?
  if request.env["HTTP_AUTHORIZATION"].nil? && session[:auth].nil?
       if APP_CONFIG['routes_login_path'].nil?
            redirect_to login_path
       else
            redirect_to APP_CONFIG['routes_login_path']
       end
  end
end

To verify if i'm logged (in all of my applications)
