Tiny Deathstars of Foulness

AppleTVs automatically update. They do so using a process similar to how iOS updates, but instead of looking at the feed I posted in http://krypted.com/mac-security/how-the-os-x-caching-server-caches-updates/, they look at http://mesu.apple.com/assets/tv/com_apple_MobileAsset_SoftwareUpdate/com_apple_MobileAsset_SoftwareUpdate.xml.

The AppleTV feed is similar to that available for iOS updates, with each dictionary having roughly the same data:

<key>ActualMinimumSystemPartition</key>

<key>Build</key>
<string>13Y6234</string>

</string>
To construct a URL to a zip, you would then simply merge the _BaseURL and the _RelativePath to the asset from the feed for a given model, in the above example, ending up with the following URL to manually download tvOS 9.2 for AppleTV 5,3:
http://appldnld.apple.com/tvOS9.2//031-53364-20160321-7C5E21F2-E7B5-11E5-89F7-525CBD379832/com_apple_MobileAsset_SoftwareUpdate/f58f4b324a9c717ea57b0cee063473a99d9e9e92.zip
BTW, Applednld is load balanced between 17.253.29.201 and 17.253.29.202, both within Apple’s Class C.
You don’t need two / characters in the path, but if you take the same process from my earlier post, you end up with
http://10.1.1.2:55491/tvOS9.2/031-53364-20160321-7C5E21F2-E7B5-11E5-89F7-525CBD379832/f58f4b324a9c717ea57b0cee063473a99d9e9e92.zip?source=appldnld.apple.com
