FYI that URL expires after a certain time (see Expires=1444350260 in the 
URL). I think by default it’s valid for an hour. Anyway, you need to make the 
GET to the cookbooks API each time and extract the URL.

Alternatively, I suppose you could find the access key and talk to the 
bookshelf service like s3, but that’s probably not a very good idea.
