In this url, it shows how to use proxy in clj-http
https://github.com/dakrone/clj-http
(client/get "http://foo.com" {:proxy-host "127.0.0.1" :proxy-port 8118})
But since we could have http proxy or https proxy, how to specify http or https? or it's mart enough to pickup the right now without the need to give http or https?
