This is a distillation of a technique we use internally at Basho to reduce the pain of cloning some of our larger repos. It relies a bit on shell scripts and environment variables, but it can be run more directly, as I show below.

1. Create a bare git repository in some directory, e.g. /var/lib/gitcache.

   git init --bare /var/lib/gitcache

2. Add all repositories you want to cache as remotes to the git repository, e.g.

require 'net/http'

# WARNING do not use this; it works but is very limited
def resolve url
  res = Net::HTTP.get_response URI(url)
  if res.code == '301' then res['location']
  else url.to_s
  end
end
