There is more to this problem then you show us. This code looks fine by itself and can be no reason to re-direct you to a wrong page. So show the relevant other code.

hi Ronald : this the complete code of admin cp index page

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Pragma: no-cache");
session_start();
if (!isset($_SESSION['username']) && !isset($_SESSION['password'])) {
header ("location: login.php");
exit;
}
include 'header.php';
require '../dbconnect.php';
$content="pages/$action.php";
        if (strlen($action)==0)
        {
        include("pages/index.php");
        }
        else
        {if (file_exists($content)) {
        include("pages/$action.php");
        }
        else
        {
        echo "page not found";}
}
mysql_close();
include 'footer.php';
?>
</body>
</html>

i also tried by adding messege under if statment instead .and that was it

if (!isset($_SESSION['username']) && !isset($_SESSION['password'])) {
echo "your not loged in";
exit;

if seesions are not set i see this msg

You are not loged in


it means that if statment is working fine and this is not cache problem .the cach problem has been solved since i added other header function at starts of the page ... the problem is with header redirection ...

HAve you tried to buffer? As in ob_start() and ob_end_flush? Like this

<?php
ob_start();
session_start();
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Pragma: no-cache");
if (!isset($_SESSION['username']) && !isset($_SESSION['password'])) {
   header ("location: login.php");
exit;
}
 
include 'header.php';
require '../dbconnect.php';
$content="pages/$action.php";
        if (strlen($action)==0)
        {
        include("pages/index.php");
        }
        else
        {if (file_exists($content)) {
        include("pages/$action.php");
        }
        else
        {
        echo "page not found";}
}
mysql_close();
include 'footer.php';
ob_end_flush();
?>
</body>
</html>

it is working even in my local webserver but not working on ifastnet.com hosting server and it does not display any php error ... is there any command that force this server to show php errors ..

[ronverdonk]

You will have to contact the administrator of that server. Not very much you can do when he/she has disabled functions or prevents some processing!
