Heroku Connection

[Joao Salcedo]

Hi All,

Nice project, amazing stuff indeed, I just have a question how can I use it on Heroku.

When I added the Memcached Add-on it provides the following

MEMCACHIER_PASSWORD:   12345678

MEMCACHIER_SERVERS:    dev1.ec2.memcachier.com:11211

MEMCACHIER_USERNAME:   xxxx

How ever when I try to connect 

(defn -main [& args]

    (let [tmc (c/text-connection (utils/get-env "MEMCACHIER_SERVERS"))

          res          (c/set tmc "a-new-key" 300 "a value")]

     (println "RESPO" @res)

))

I have the following error:

lein run -m conejo.memcached.core

You are not using credentials in this code.

Passing authentication credentials currently requires direct Java interop and a bit of

knowledge of the SpyMemcached API. Feel free to submit a pull request that

makes that better, I believe it belongs to this function:

https://github.com/clojurewerkz/spyglass/blob/master/src/clojure/clojurewerkz/spyglass/client.clj#L36

I hope to look into this for 1.1.0-beta2.

Please give 1.1.0-beta2 a try, it includes authentication support

but I haven't tested it with a live instance on Heroku:
