Google Analytics

I have tried every script program and what not I could find out there to generate fake traffic on a site. NONE of them is actually working the way they advertise it. While some can work with youtube, real sites analytics do not show ANY traffic. Google Anal;ytics seems to ignore any GET request or POST requests I have thrown out there.
I have used proxies (I have good proxies) but nothing seem to work. Any script (PHP, Perl .. name it) or program you have tested worked for you? Let me know!

GA uses javascript to track visitors, so check if js is supported by the script
