ID: 40390 Updated by: vrana@php.net Reported By: razvan dot pop at micronets dot ro -Status: Open +Status: Bogus Bug Type: Documentation problem Operating System: Irrelevant PHP Version: Irrelevant New Comment: It doesn't prevent the headers to be sent, it just send them empty. Previous Comments: ------------------------------------------------------------------------ [2007-02-07 16:40:34] razvan dot pop at micronets dot ro Description: ------------ The documentation page for the header() function (http://www.php.net/manual/en/function.header.php) doesn't officialy state that setting headers in this manner: header('Cache-Control:'); header('Pragma:'); will prevent those headers from being sent even if previously set. Ie. it will efectively delete the headers. Reproduce code: --------------- <?php session_cache_limiter('nocache'); session_start(); header('Cache-Control: max-age=10000'); header('Pragma:'); // deletes "Pragma: no-cache" set by // session_cache_limiter header('Expires:'); ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40390&edit=1
