Using browser cache for cookie-less user tracking is really smart. Assigning an identifier as Last-Modified or Etag response header and then tracking those subsequent requests seems unstoppable.

Is this why cross-domain requests have their isolated caches even for things like Google fonts, JS libraries, etc?
