Session cookie not available in document.cookie

I can see the cookie is being transmitted via Chrome Network inspector:

But when I dump document.cookie to the console I don't see it! Entire contents of served file:

<script type="text/javascript">
    console.log(document.cookie)
</script>

Is this normal?

HttpOnly is an additional flag included in a Set-Cookie HTTP response header. Using the HttpOnly flag when generating a cookie helps mitigate the risk of client side script accessing the protected cookie (if the browser supports it).
