Changed format of url variable

So i'm trying to mush together the format here:
http://coffeescriptcookbook.com/chapters/networking/basic-http-client

with the logic here:
http://nodejs.org/api/http.html#http_http_request_options_callback

hopefully this does it. If not, will need to do:

(res) ->
    data = ''
    res.on 'data', (chunk) ->
        data += chunk.toString()
    res.on 'end', () ->
        answer = data
