Recently I discovered that @amalloy's answer doesn't work when the Clojure/Compojure app is run under Jetty or Tomcat as a .war. In this case :path-info needs to be updated. Also, I think this version will handle any route, not just the "root" route.

(defn- wrap-dir-index [handler]

         (assoc request k (format "%sindex.html" v))
         request)))))
