lol wtf.... Javascript cant prevent DDOS....

I coded a flooder that can bring a dedicated host running VB to 200% usage. Which scares me, currently im working on prevention.

Most flooders dont even look at the page usually they just send Requests a header to the server, then the server responds.

You can't really prevent a DDOS attack at the application level. At the very least you'd have to do it at a router level, and drop packets from the hosts that are flooding you. And that will only work if you have enough bandwidth up to the router.
