Html displays blank in AIR3.X?

I have a problem while using Html compents in AIR .Some websites displays blank.

the code:

<mx:HTML id="html"  location="http://car.bitauto.com/rongweir95/koubei/"

    locationChange="htmlLocationChange()" htmlRender="htmlLocationComplete()"  htmlDOMInitialize="html_htmlDOMInitializeHandler(event)"

    width="100%" height="100%" complete="com(event)" uncaughtScriptException="html_uncaughtScriptExceptionHandler(event)"

    />

does anyone have the same question,or anyone have the way to solve it?

ps:other websites,such as "http://car.bitauto.com/rongweir95/youhao/",can display correctly,

and if i save "http://car.bitauto.com/rongweir95/koubei/" to the localhost,it works well.
