# This script is intended to redirect the visitor as per the parameters 
# passed as Query string. In addition it also writes in a log file - all 
# the transaction details - date,time,parameter passed,User_ip and where he 
# came from. There is an admin script to check the logs.In case you invoke
# the script without any parameter, it sends them to a page selected at random.
