I want to test something against a local proxy:

(require '[aleph.http :as aleph]
         '[manifold.deferred :as d])

(def aleph-pool (aleph/connection-pool {:connection-options
                                        {:proxy-options {:host "localhost"
                                                         :port 8080}}}))

(d/on-realized (aleph/get url {:pool aleph-pool})
               (fn [r] (println "Status: " (:status r)))
               (fn [e] (println "Error type: " (type e))))
