According to Developer "RefRef is a revolutionary DoS java site. Basically, by using an SQL and .js vulnerability, you can send a page request packet from your home computer with embedded .js file, because of the vulnerability in the SQL/Javascript engine on MOST websites, the site actually TEMPs the .js file on its own server. So now the .js is in place on the host of the site. Next since you still have the request, it picks up the .js file, and all of the requesting for packets power happens on the server, not the requestee. I send two packets from my iphone, and everything else happens on the server. Basically eats itself apart, because since both are on the server, its all a local connection."
