It is, indeed, a matter of "making sure you deliver ETag: response
header from the backend" and everything is set. From now one the
clients should "see" this ETag: header in the response, and then start
issuing If-None-Match: request headers in the next "conditional GETs"
they made. Then, you have an improved chance of delivering 304 instead
of 200 + full content.
