Hmm. I tried this:
(-> (io/resource "public/html/confirm.html")
(cr/render)
(resp/header "Cache-Control" "no-cache, no-store"))

Exception in thread "main" java.lang.IllegalArgumentException: No single
method: render of interface: compojure.response.Renderable found for
function: render of protocol: Renderable, compiling:(pts/server.clj:483:14)
