www can't download file in webplayer

The file is on my http server,and it work well in the editor; but when i published the webplayer, it dosn’t work , in the %temp%/UnityWebPlayer/log/log_343a*********.txt, the last line is “starting www download: http://loclahost/game/webplayer/female_base.assetbundle”;
WWW.isDone won’t be true forever.

I found that the WWW.progress is 1.0f, but the WWW.isDone is false, what’s the wrong with webplayer?

Are you sure you have a crossdomain policy on your server and you have Unity pro?

Read here about the security sandbox and here about AssetBundles

Yes i’m sure that the crossdomain had on my server, and it work well in editer, but will be work well on published exe sometimes, in the webplayer it dosn’t work.

I found an answer at WWW in WebPlayer vs. standalone - Questions & Answers - Unity Discussions.

I have another problem after up question, the LoadAsync is crashed after WWW.isDone;
