Clojurians Log v2

Hi all! I am working with lacinia-pedestal and I want to add cookie-sessions. Here's my handler:

(defn handler
  "Ion handler. Start up backend processes."
  [service-map]
  (-> service-map
      (assoc ::http/resource-path "/public"
             ::http/allowed-origins (constantly true)
             ::http/chain-provider provider/ion-provider
             ::http/enable-session {:store cookie/cookie-store})
      cast-log
      http/create-provider
      cast-log))

which enables the Ring middleware session interceptor. Unfortunately, I am having difficulty writing an interceptor that will put a session on the HTTP browser. I would appreciate any suggestions, help, etc. you might have on this. Thanks!
