This is plain *wrong*. Vary refers to the *request headers* not the
*response headers*.

IE 6.0 seems very buggy in this case to me.

Having said that, a better test case for you would be

header("Content-Encoding: gzip");
header("Vary: Accept-Encoding");
header("Expires: Mon, 08 Dec 2003 00:00:00 GMT");

Which should cache just fine in any http/1.1 browser.
