Bug description: ob_gzhandler overrides Vary header
Description:
------------
I am using ob_gzhandler to compress the page output. Now I need to add an
'accept-language' to the Vary header, because my page content depends on
the language settings of the browser.
Anyhow, it is impossible to change the Vary header when using
ob_gzhandler. It seems like ob_gzhandler is overriding an existing Vary
header just before returning the compressed content to the browser.
Expected behaviour: ob_gzhandler should check if a Vary header has already
been set. If so, it should only ADD an "accept-encoding" unless already
present, or should not change the Vary header at all.
Reproduce code:
---------------
<?php
header("vary: accept-encoding,accept-language");
ob_start('ob_gzhandler');
print("<html><body>foo</body></html>");
?>
Expected result:
----------------
A HTTP header "vary: accept-encoding,accept-language" being returned.
Actual result:
--------------
A HTTP header "Vary: Accept-Encoding" (note the uppercase letters) will
always be returned.
