note 20506 added to function.header

header() does not replace headers but always produces duplicates At least with PHP 4.1.1/Win32(XP), the "replace" parameter has no effect - headers are always added up. Using this little test: <?php header('X-Test-Header: Version 1'); header('X-Test-Header: Version 2'); ?> this output is created: ------------------------------------- php headers.php X-Powered-By: PHP/4.1.1 X-Test-Header: Version 1 X-Test-Header: Version 2 Content-type: text/html ------------------------------------- According to the docs, only "Version 2" of the header should be sent. The results are identical if you do not provide the "replace" parameter, or if you set it to true or false. This is a very annoying bug, and for my application I'd rate it "critical".
