Question

I have TYPO3 version 7.6.18

    public function uploadProgressAction(){
        session_start();
        echo $_SESSION['progval'];
        return false;
    }

    /**
     * action create
     *
     * @param \Istar\Fefiles\Domain\Model\Video $newVideo
     */
    public function createAction(\Istar\Fefiles\Domain\Model\Video $newVideo)
    {
        session_start();
        $progress_percents = 0;
        while(1 ==1){
            $progress_percents = $progress_percents + 1;
            $_SESSION['progval'] = $progress_percents;
            session_write_close();
            sleep(0.5);

调用session_write_close() ，您的会话已关闭..并且您无法再对其进行写操作。
