This issue has long been recognised since zlib.compression feature was
implemented.
The behaviour is quite expected => marking this as a feature request.

If zlib.output_compression is on, then it (sensibly) sends a
Vary: Accept-Encoding
header to the browser. However, if the user's script has sent its own
Vary: header, then that header will get clobbered by zlib's. Better
solutions would be to either:
* let the user's header take preference, and caution the user to
include Accept-Encoding in the custom one, or
* magically combine the user's header and the zlib one.
Refernece: RFC 2616 (HTTP/1.1 Spec), Section 14.44
Sample script:
<?php
ini_set('zlib.output_compression', 'on');
// do something with $_SERVER['HTTP_ACCEPT_LANGUAGE']
header('Vary: Accept-Language');
// output something
?>
