如题，网上说是由于sessionid为空导致的，需要通过url传sessionid，那url应该怎样编写？
我试了把URLRequest改成http://localhost/file.php?phpsessid=test，服务端的file.php文件内添加了session_id($_POST['phpsessid']);session_start();结果还是不行，到底要怎样才行？
之前写的一篇文章，你看下是否对你有帮助PHP之uploadify在框架中上传302错误的总结
i don't know what is the problem,i give up,it dosen't matter to me now.Maybe it was the php_ini block the url sending sessionid to server.
