I believe we still need this info.update here. There are cases where is more than just headers iirc.

And I had completely forgotten that my normalize_headers didn't do anything with lowercasing. So we'll need to add lowercasing back in. Although I'd recommend not doing the lowercasing in normalize_headers. I'd still do that on info, since it is a specific implementation detail of fetch_url.

We can keep lowercase in normalize_headers function and add an extra argument to the function to activate lowercasing (false by default) ?
