Project : google adword Cloaking web script script language : PHP, CGI, PERL , JAVASCRIPT , AJAX, XML Cloaking script What is it? The script should recognize Google bot (Google spider ip's) and as soon as it enter your website to check it the script will show the spider visitor a highly optimized web page (redirect him to a domain1) For all other users which are not google related the script will redirect them to a different website (domain2) I have a few more simple features & filters I want for this cloaking script project but I will tell only to serious programmer that want to take on this project. Please only quality programmer with proven past results or that have already done similar project in the past that can get projects done Thank you
