動態輸出的swf，不能被 flash player 10 載入?

原來是 flash player 10 在搞鬼 ，當header 有 Content-Disposition: attachment 時，flash player將放棄載入。我的用法如下：

//php

if ( !$_SERVER["HTTP_X_FLASH_VERSION"] ){
header('Content-disposition: attachment; filename='.basename($openswf));
}

'asp

IF Request.ServerVariables("HTTP_X_FLASH_VERSION") = "" THEN
Response.AddHeader "content-disposition", "attachment; filename="&filename
END IF
