Sessions

Hi All, I'm struggling with a session problem and I'm not sure where I should be looking for the answer. Most of my pages begin like this: ==================================== include_once('cfheader.php'); $feedback = cfHeader("Main Page"); //Start of page code ==================================== The cfheader.php file begins like this: ==================================== <?PHP session_start(); function cfHeader($Title,$Protect=false) { $feedback=""; //IF we're loggin on then destory and get new session if (IsSet($_POST['login'])) { include_once('userreg.inc'); session_destroy(); //Destroy current session before continuing $feedback =do_login(); } if ($Protect==true && !IsSet($_SESSION['name'])) { //No Session. echo "<META HTTP-EQUIV='refresh' content='2;URL=mypage.php'>"; //Redirect exit; } ==================================== This works fine on my development PC, (PHP v 4.3.1) and on my primary test site (PHP v4.2.2). However when I try it on the target site (PHP v4.1.2) then I find that immediately after starting the session everything works fine, however when I move to any other page the session information is lost and I'm redirected to log in again. I was looking over the PHPInfo but to be honest I can't see what it is that's different. All help is gratefully appreciated. regards, Dave --- Outgoing mail is certified Virus Free.
