I frequently find myself check-summing the request/response with a
simple incrementing integer (or UUID would work) and storing the
checksum of the last request on the client. If the server responds
with anything other than the last request then I may display it
(depending on how long it has been since I last updated the UI so it
appears responsive) or more likely disregard it.
It can be as simple as an atom {} where the key is the unique
identifier for the semantic request (e.g. :page1/field-a) and the
value is the checksum of the last request to the server.
Pseudo code, in case it isn't clear (and if it isn't I haven't
explained it well as it is brain dead simple :)):
(defn do-request [request-key details handler]
(let [checksum (swap! checksums assoc request-key inc)
stale-aware-handler (fn [{:keys [checksum] :as response}]
(when (= checksum (:request-key @checksums)) (handler response)))
(ajax-malarky-send details stale-aware-handler)))
In my form:
(defn field-a []
[lovely.hiccup.something {:on-click #(do-request ::field-a (-> %
....) request-results)}])
(defn field-b []
[lovely.hiccup.something {:on-click #(do-request ::field-b (-> %
....) request-results)}])
Typed on the fly so probably all sorts of things wrong with it ;), but HTH.
