note 52144 added to function.headers-sent

[code] <?php header("Cache-Control: private, must-revalidate, max-age=3600, post-check=3600, pre-check=3600"); ////header("Last-Modified: " . gmdate("D, d M Y H:i:s",getlastmod())." GMT"); ////ini_set("last_modified","1"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); flush(); // <= (*1) ... if (!headers_sent()) { header('Content-Type:text/html; charset='._CHARSET); header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); //header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); header('Cache-Control: private, no-cache'); header('Pragma: no-cache'); } ... ?> [/code] headers_sent() does not evaluate it as true, unless the flush()(*1) has been done. It seems that it does not mean header was sent unless a header output is taken out to the exterior of PHP. Apache 2.0.53 (prefork) PHP 5.0.3 (server module) ... And XOOPS 2.0.9.2 I had seldom paid attention to flush() on PHP which is not C. However, it might have been a required thing.
