由coffeecup iframe超时的PHP会话

Question

I have a small form that I made with CoffeeCup form builder. It loads inside of an Iframe in the page. The problem is that it expires my PHP session when ever it loads. I went to the file that is being loaded into the iframe and put session_start(); at the top, but whenever I navigate to that page the session becomes destroyed.

If you're not familiar with coffee cup, here is the code that is loaded into the Iframe.

    <?php
    session_start();
    $scriptpath = substr( $_SERVER['SCRIPT_FILENAME'], 0, -4 );
    $paths = explode ( DIRECTORY_SEPARATOR , $scriptpath );
    $myName = end($paths);
    require $scriptpath . '/fbapp/php/config.inc.php';


    if( strtoupper( $_SERVER['REQUEST_METHOD'] ) == 'POST' ) {

$ctl = new FormController();
$ctl->Dispatch();

    } else {

if( ! isset( $_GET['action'] ) )        $myPage->ReportStats(                         'NotifyFormView' );
    }

    ob_start();

    $myPage->Show();
    ob_end_flush();

    ?>




    <script type="text/javascript">document.write(unescape("%3Ciframe id=\"fb_iframe\" src=\"redeem.php" + window.location.search + "\" width=\"100%\" height=\"379\"allowtransparency=\"true\" scrolling=\"no\" frameborder=\"0\"%3E&lt;a href=\"redeem.php\" title=\"redeem\"&gt;Check out my CoffeeCup Form&lt;/a&gt;%3C/iframe%3E"));</script>

Any help is appreciated.
