Content Caching is totally unreliable!! I have found the following:

1. Sometimes caches Mac app downloads but won't serve them

from cache to other Macs.

2. Sometimes when Mac App Store downloads are done on a Mac,

the caching server doesn't even recognize the that a request was

made for an app.

3. Sometimes serve content to a particular Mac and other times won't.

Which Mac is "blessed" to receive cached content is totally random.

4. On very rare occasion, actually does what it is supposed to. But almost

never on the very large downloads where one would really want it to work!


Bottom line, Content Caching is useless as far as Mac App Store downloads

are concerned. BTW, all the Macs involved are all using the same AppleID

and logged into iCloud with the same AppleID and are all registered with

Apple with the same AppleID!


One good thing, perhaps, if you have a bunch of iDevices, it does seem to

work for them.

Similar Problem here. Starting from 10.13 the caching server is no longer providing OS X Updates to clients. Safari and some other Apps seem to load from the caching server but only randomly.

FWIW, I have been fighting this for a while and have simply given up.

It seems that Content Caching either works or it doesn't and when it

doesn't, no one has a clue as to why!


Also, when it was part of the Server app in the 4.x versions it had worked

flawlessly. Somewhere in the 5.0 to 5.3 upgrade chain it broke and moving

it from Server app to High Sierra did not do anything to fix it!
