Based on my reseach, I came up with the following: we need etag off; we should create a file with the git last modification time of the files, updated when there is a new commit in the repo => last-modified we should create a file with some hash of the files, updated when there is a new commit in the repo => etag we could restrict these operations to the files modified since the last checkout.
