I'm going to assume that you are tired.

Yes, the server sends a `cache-control` + `expiry` but It does not matter, since it never sends either an `eTag` nor `Last-Modified` which means that the browser has no value to include with an `If-None-Match` nor an `If-Modified-Since` nor anything else.

If the server does not send a `Last-Modified` value, how the heck is the browser supposed to know what value to add to it's `If-Modified-Since` header?!!!

As I said at the top, I'm going to assume that you are tired.
