Uploadify gives error HTTP Error (302) in yii

Question

Yesterday I integrated uploadify in a Yii application and it worked good. But suddenly I found that it does not work rather showing error HTTP Error (302). I found this is happened only firefox, IE and Crome are okay.

In below of main.php file I wrote:

<?php $timestamp = time();?>
$(function() {
    $('#file_upload').uploadify({
        'method'   : 'post',
        'auto'     :false,
        'multi'    : true,
        'formData'     : {
            'timestamp' : '<?php echo $timestamp;?>',
            'token'     : '<?php echo md5('unique_salt' . $timestamp);?>'
        },
        'swf'      : '<?php echo Yii::app()->request->baseUrl; ?>/images/uploadify.swf',
        'uploader' : '<?php echo Yii::app()->createUrl('cp/project/UploadImage')?>'

    });
});

and in controller:

public function actionUploadImage(){
    $directory = Yii::getPathOfAlias('webroot').'/images/temp';
    if (!is_dir($directory)) {
        mkdir($directory, 0777, true);
    }

    $verifyToken = md5('unique_salt' . $_POST['timestamp']);

    if (!empty($_FILES) && $_POST['token'] == $verifyToken) {

        $tempFile = $_FILES['Filedata']['tmp_name'];

        $filename  = basename($_FILES['Filedata']['name']);
        $extension = pathinfo($filename, PATHINFO_EXTENSION);
        $newName       = md5(time()).'.'.$extension;

        $targetFile = $directory . '/' . $newName;

        $fileTypes = array('jpg','jpeg','gif','png'); // File extensions
        $fileParts = pathinfo($_FILES['Filedata']['name']);

        if (move_uploaded_file($tempFile,$targetFile))
        {
            $model = new ImageTemp();
            $model->user_id = Yii::app()->user->id;
            $model->image_hash = $newName;
            $model->session_id = Yii::app()->session['imageUpload'];
            $model->save();
        }

    }
}

Everything was good but suddenly, I have been facing this error.

302 is technically not an error, it's a redirect. Based on past experience, I am guessing Firefox is not passing session cookies in the Flash request, so Yii is telling it to authorize first. If that is indeed the case, you will need to implement something similar to uploadify.com/documentation/uploadify/… . — user1233508

I have solved the issue and left answer here how I have fixed if anybody got any help. As per reference of uploadify http://www.uploadify.com/documentation/uploadify/using-sessions-with-uploadify/ and http://www.uploadify.com/documentation/uploadify/customizing-the-server-side-upload-script/ I wrote at the beginning of the controller :

function init(){

    if(isset($_POST['SESSION_ID'])){
        $session=Yii::app()->getSession();
        $session->close();
        $session->sessionID = $_POST['SESSION_ID'];
        $session->open();
    }
}

and initialized uploadify as:

$session_id = Yii::app()->session->sessionID;
$session_name = 'SESSION_ID';
$swf = Yii::app()->request->baseUrl.'/images/uploadify.swf';
$uploadifyImg = Yii::app()->createUrl('cp/project/UploadImage');
Yii::app()->clientScript->registerScript('uploadify', "

$(function() {
    $('#file_upload').uploadify({
        'method'   : 'post',
        'auto'     :false,
        'multi'    : true,
        'formData' : {'$session_name' : '$session_id'},
        'swf'      : '$swf',
        'uploader' : '$uploadifyImg'

    });
  });
");

It would helpful who face such issue.
