<http://www.php.net/header>:
void header ( string $string [, bool $replace [, int $http_response_code]]
)

The optional replace parameter indicates whether the header should replace
a previous similar header, or add a second header of the same type. By
default it will replace, but if you pass in FALSE as the second argument
you can force multiple headers of the same type.
