How to spoof video views (to get more views on videos like at metacafe or youtube)

Can anyone explain to me how the video views on metacafe or youtube work. As in, how do they count you only once and how would you make it so you can generate a butt load of video views. Any help/links are welcome, thanks.

i assume they use sessions to track unique visits (the visit lasts until your cookie expires or is cleared). they could also be doing it based on IP and a timeframe for "uniqueness" but the most common way i've seen is the session method. Read up on PHP's sessions and $_SESSION to understand how this works and you should get an idea. enjoy

Very useful, thanks.
