Are calls to dl.boxcloud.com chargeable? Do they count against the monthly API limit?

I know that calls to api.box.com count against an API limit of 50k to 100k calls. Do requests to `dl.boxcloud.com` count against that limit as well? 

e.g., if I call `https://api.box.com/2.0/files/:file_id/content`, is that two chargeable requests counting the redirect, or one?
