SESSION ID ISSUe?

programming
1

When using the session start code for my clnt login pages - it seems that it does not carry over to the next page once in the member section.

after logging in - i see the proper clnt info on the main profile page - however when i click to view another clnt page - my browser takes me to the login page which is the page i coded the user to go to if credentials are not saved.

please look at my code and let me know if anything is wrong. thanks!

this is the php file that is loaded once logged in, this page directs you to the proper verson depending on which browser you are using:

 
<?
session_start();
$_SESSION['logname']= $user;
$clientN = $_SESSION['client'];
$me = $_SESSION['name'];
$me2 = $_SESSION['name2'];
if (@$_SESSION['auth']!="yes")
{
header("Location: ../personal_account_login.php");
exit();
}
?>

}
}
</script>

<body onload="detectBrowser()">
</body>
</html>

at the begining of each page i placed the session start as follows:

<?
session_start();
$_SESSION['logname']= $user;
$clientN = $_SESSION['client'];
$me = $_SESSION['name'];
$me2 = $_SESSION['name2'];
if (@$_SESSION['auth']!="yes")
{
header("Location: ../personal_account_login.php");
exit();
}

however when using the MOZILLA pages only, when i click on the navbar to visit another
member page - i am redirected to the login page mention in the above code - however it should not as long as the session id’s are being carried over! all member pages has this code at the begining of the page. Please help if there is an issue with the syntax
thanks!
