I've seen a lot of people do this, so I have to comment. The last Cache-Control header REPLACES any other Cache-Control headers set previously unless you specify not to. http://us2.php.net/manual/en/function.header.php The header Cache-Control: no-cache, cachehack=time() will never be sent because the second one replaces it. The third one uses the second argument to specify that it should not replace the existing one. Of those three Cache-Control lines, only two will even be sent to the browser.
