I get the issue but I do strongly feel that you should expect http resources to be cached. It's so common of a thing expecting it to never be cached is unreasonable as a design.

I would expect the headers to make this clear, however.

I actually don’t. Git already has a file on the filesystem. Serving a plain file is as close to caching as you are going to get.

Guess we may as well throw our handa up in the air then and set a 14 year cache ttl.
