I've just managed to work out how to do this. Actually, there are a number of
ways to do it, but I think, given you are using luminus, this is the easiest.
The basic idea is to add a javascript variable to the page which holds the
anti-forgery token. Luminus makes this quite easy as it already adds the
csrf-token variable as a standard part of the selmer template. If you add
<script type=javascript>
var csrf = "{{csrf-token}}";
</script>
to the page template, then your clojurescript can get the value in js/csrf and
either use that to setup the hidden variable in your javascript generated forms
or if you are doing something like cljs-ajax, add it to the headers when
makeing the request to the server.
