Yes, your response is really cached at least in MSIE 5.5.
I have just investigate this.
Responses with "Vary: Accept-Encoding" and "Content-Encoding: gzip"
are cached by MSIE. The "Expires" header is not needed.
Responses with "Vary: Accept-Encoding" but without "Content-Encoding: gzip"
are not cached by MSIE.
Furthermore, responses with "Vary: Any,dummy,words" and
"Content-Encoding: gzip" are also cached by MSIE.
And as I said before responses with "Vary: Any,dummy,words" and
without "Content-Encoding: gzip" are not cached by MSIE.
All these was tested with MSIE 5.5 only.

I mean that handler can do following:
if ($r->headers_in("Accept-Encoding") =~ /gzip/
and not $r->note("disable_gzip"))
{
do gzipping
}
