Smartrouter

Smart Router is a simple yet intelligent redirect script. It can also be used to hide the valuable html code that you used to place high on search engines. Smart Router is very easy to set up and maintain, and runs via Server side includes. When someone attempts to view a page that is set up with smart router, the script runs and checks to see where the surfer is coming from (the last web page the surfer was viewing when he clicked the link to go to your site). The script then decides where to send the surfer based on information you give the script ahead of time.
