I figured it out. You need to find: $_response_body = preg_replace('#\<\s*body(.*?)\>#si', "$0\n$_url_form" , $_response_body, 1); Code (markup): and right before that you put your code.
You are not allowed to put AdSense on the proxy generated pages (if you get my drift.) It is against the AdSense ToS. The OP was asking abut AdBrite not AdSense.
