Remote Cookie ID and Web Statistics

Hello, - for something a little different... Does anyone have experience using Javascript on remote server html delivered pages to capture data in a PHP MySQL database resident at my domain. I would like to build a customer profile database for a customer using a permanent cookie on a visitor's browser client to ID them and track their visits by page over time. This is similar to a live or remote web statistics process for a session but posting to a mysql database by some mapped category by page in addition to the web stats. I'd like to track both the session and by posting to a visitor database, long term trends as well. Any suggestions would be appreciated. Thanks, Rick rls@InfoTech-eDirect.com
