Right, this can't operate as a transparent proxy. However, it could work 
in combination with insteadOf on the client, e.g., if the repo URL is 
https://example.com/foo/bar.git, the CI builder could set a global 
insteadOf in /etc/gitconfig before kicking off the job:

[url http://local.proxy]
  insteadOf = https://example.com

This way CI job maintainers could continue to use canonical repo URLs, 
but actual requests would go out to the local proxy and be cached.
