Q: Caching Server service still broke for Mac App Store apps

Well, I thought I had found a fix to my issue of downloads from the Mac App Store not caching.

WRONG!

I explicitly set the flags, via terminal commands, for AllowPersonalCaching and AllowSharedCaching

as the two flags were not present in config.plist for the service.  I then downloaded an app from the

Mac App Store on one of my Macs and it did actually get cached and served from the Caching Service.

Well, thought all was good, until today!

Saw that I had an update for 1Password app.  So downloaded it from the MacApp Store onto my iMac.

Then I thought, better check my MiniServer to see if the Caching Service was still working for MacApp

Store downloads.  Guess what?  NOT!!!  Did the update on two other Macs and the Mini Server and none

of them made the Caching Service budge!

However, all the Macs do see the caching server and a look in the log shows that the Caching Service is working

for local iCloud caching as when each Mac was powered up for the update I was attempting, there were multiple

PUTs and GETs for cloudd/xxx.xx.

Now, on top of that, the formerly working iTunes Store app update caching when downloading on the Macs is also

not working any more!!!  It did however, serve an app directly to an iDevice that I tested.

So, has the Caching Service just basically a useless consumption of memory now in terms of working with Mac? 

Has it turned into an iDevice only service?  I have tried re-starting the service, shutting down the Server app, rebooting

the server all to no avail.

All the functionality of the service was fine under Yosemite.  Somewhere along the line though, either El Capitan updates

or Server App updates have some how borked this service.

So, any clues or do people simply not use this service anymore and no one cares?
