netty is excellent if you want NIO for performance. But for requesting
a URL - really quite massively overkill. You can write a URL request
in a threaded way very simply (even containing a callback if you want
one):
(ns fin
(:require [clojure.contrib.duck-streams :as ds]))
(defn history [stock]
(ds/read-lines
(java.net.URL. (str "http://ichart.finance.yahoo.com/table.csv?s=";
stock "&a=0&b=1&c=2003&ignore=.csv"))))
(defn callback [] (println "done!"))
(future (history "RIO.AX") (callback))
So it really depends on your goals.
