@jondthompson the Caching service as part of Server.app 2.2.1 did serve software updates when accessed by clients running 10.8.2 or later, the one in Mavericks server also serves these other content types.
Also, people are seemingly coming to this thread without context, just to be explicit this gist seems like it was originally helpful for folks using the wdas/reposado project.
