Description:
------------
Hi,
if using ob_start("ob_gzhandler")
in combination with flush() 
it seems php send wrong HTTP header to the Browser (see Reproduce code).

Thank you
Hans-J?rgen Petrich


Tested with 
Linux OS (Kernel 2.4.20)
Apache2 (2.0.47)
PHP 4.3.4RC1 (as Apache2 Handler)
'./configure' '--with-mysql=/usr' '--with-zlib' '--with-apxs2' 
default php.ini-dist is used






Reproduce code:
---------------
<?php

ob_start("ob_gzhandler");
//header('Content-Encoding: gzip');
//header('Vary: Accept-Encoding');
?>
<html>
<body>
<p>This should be a compressed page.
<? flush();?>
</html>
<body>

Expected result:
----------------
HTTP/1.1 200 OK
Date: Sat, 11 Oct 2003 16:53:06 GMT
Server: Apache/2.0.47 (Unix) mod_ssl/2.0.47 OpenSSL/0.9.6b DAV/2 PHP/4.3.4RC1
X-Powered-By: PHP/4.3.4RC1
Content-Encoding: gzip
Vary: Accept-Encoding
Connection: close
Content-Type: text/html; charset=ISO-8859-1


Actual result:
--------------
HTTP/1.1 200 OK
Date: Sat, 11 Oct 2003 16:53:36 GMT
Server: Apache/2.0.47 (Unix) mod_ssl/2.0.47 OpenSSL/0.9.6b DAV/2 PHP/4.3.4RC1

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.
