note 46049 added to function.header

some browsers always reload stylesheets, javascripts and other seldomnly changing files, which causes nasty delays when loading a website (Safari on MacOS is an example) to tell the browser to keep files in cache for at least a day, you can use <?php header('Expires: ' . gmdate('D, d M Y H:i:s', time()+24*60*60) . ' GMT'); ?> This has the nice sideeffect of telling other browser that never refresh pages to refresh them at least once a day. PS: i figure this is trivial, but it cost me some headache ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46049 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46049&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+46049&report=yes Search -- http://master.php.net/manage/user-notes.php
