The current port number is available in the Net::Http object

     h = Net::HTTP.new(ARGV[0] || 'www.ruby-lang.org', 80)
     p h.port  #=> 80


Using Tomoyuki Kosimizu's URI package, available in the RAA, you can
readily split the information out of the redirect response:

       if head.code == "301"
         uri = URI.create(head['location'])

         host = uri['host']
         url  = uri['path']
         port = uri['port']
         
         h.finish
         h = Net::HTTP.new(host, port)

         retry
       end

Between them, do these do what you need?
