1Headers will be overriden if defined more than once. So, the second one. – zxcmehran Oct 27 '15 at 17:49

On this script the second header() will be used:
<?php
header('Location: http://google.de');
header('Location: http://stackoverflow.com');
On your script the second header() will be used:
<?php
header("Cache-Control: public");
header("Cache-Control: private");
If a header was defined multiple times, the last one will be used!

To elaborate on this answer, if an `exit;` were placed after the first header, then the last one will not execute. – Funk Forty Niner Oct 27 '15 at 17:49
