推荐答案

小程序可以连接到他们曾经下载​​的服务器（同源策略）。从6u10中，他们也可以与相应的的crossdomain.xml 文件（google一下）。访问网站

Applets can connect back to the server they were downloaded from ("same origin policy"). From 6u10 they can also access sites with appropriate crossdomain.xml file (google it).

随机允许访问的任何网站显然不会是良好的安全性。您可以登录您的code和有插件允许用户删除安全。但是，你需要知道的安全做安全的（大多数人不）。对于好安全对话需要由受信任的证书颁发机构签署的证书。

Randomly allowing access to any site obviously isn't going to be good for security. You can sign your code and have the PlugIn allow users to remove security. However, that requires you know about security to do it safely (which most people don't) . For a "nice" security dialog you need a certificate signed by a trusted certificate authority.

另一种选择是让你的Web服务器转发机上的连接。然而，又是棘手的安全做。

Another option is to have your web server machine forward on connections. However, that again is tricky to do securely.
