     # example
     response = http.request_post('/cgi-bin/nice.rb', 'datadatadata...')
     p response.status
     puts response.body          # body is already read in this case

     # using block
     http.request_post('/cgi-bin/nice.rb', 'datadatadata...') {|response|
       p response.status
       p response['content-type']
       response.read_body do |str|   # read body now
         print str
       end
