Strange problem with session and header("Location:script.php?".SID)

Hi, I have very strange problem with sessions. There is a class MyApp which does certain jobs, and instance of this class (not shown here). In function OpenMainPage() I have started session, assigned name to it and registered certain variables. file: MyApp.php class MyApp { // --- MORE STUFF HERE

    function OpenMainPage()
    {
        $res = $this -> mDb -> Execute('SELECT * FROM contacts');
        if ($res -> RecordCount() == 0)
            $this -> SetupDefaultDBRecords();

        session_start();
        session_name('MyApplicationSession');

        $aaa = "blah blah blah";
        if (! session_register("aaa"))
            echo "failed to register variable";

        header("Location:StartupPage.php?".SID);

} } ---------------------------------------------- Then I would like to pass the control to script called StartupPage.php using header("Location:StartupPage.php?".SID). file StartupPage.php //include_once('anvgwg_session_start.php'); session_start(); echo session_name(); // prints PHPSESSION or something like this echo $_SESSION["aaa"]; // prints nothing ---------------------------------------------- However, session seem to be terminated, although I have used SID. I

have tried to move         session_start(); session_name('MyApplicationSession') to the first script where the instance of MyApp class have been created and used, but the result is the same. I have checked PHP options (default install of PHP 4.2.3 and Apache2 on SuSE Linux 8.2), enable-trans-sid and track-vars options are on, so it should work. Quite strange, but {echo SID} prints nothing, although { echo session_ID() } prints long cryptic string. I have some other PHP programs installed on my server, but they working without problem header("Location:script.php?".SID) without cookies (my app should work without cookies enabled in browser).

Anyone have an idea what is wrong?
