Thanks.

That was going to be my next question. So, IdP 2.2 (and later)
supports HTTP conditional GET (ETag and Last-Modified in the response,
and If-None-Match in the request) as well as HTTP compression
(Accept-Encoding in the request and Content-Encoding in the response).
Is that correct?

In the request, what exactly is the value of the Accept-Encoding header?
