We're using PlayFab with Unity3D 4.7.2 for the WebPlayer target. Due to the sandboxing of the WebPlayer target, it requires a `crossdomain.xml` from the host that you're trying to fetch from. Now the API works fine, but when we try to download from the CDN ( `https://cdn.playfab.com` ) it also tries to fetch a `crossdomain.xml` at the root of that address, and since there isn't one, it fails. That leaves us unable to download from the CDN on the WebPlayer target.
