I wonder if we even need a separate service like this.

Wouldn't a new protocol capability that is advertised from
upload-pack sufficient to tell the "git clone" that it can
and should consider priming from this static resource?

Two minor comments:

 - For whom are you going to localize these strings?  This program
   is running on the server side and we do not know the locale
   preferred by the end-user who is sitting on the other end of the
   connection, no?

 - Turn "}\n\s+else " into "} else ", please.
