It would either be SSI or PHP
Code:
<!--#include virtual="/cgi-bin/at3/in.cgi" -->
or
Code:
<?php virtual ("/cgi-bin/at3/in.cgi"); ?>
The code will have to be modified to the excact path ofcourse.
The script I was thinking of is AT3 (Arrow Trader Lite III) from
www.arrowscripts.com - mostly used on traffic sites.
It will only be to track incomming hits and I will be able to add all the sites I submit to and see who sends traffic and from which categories for example. And ofcourse for SE hits.
