如果安装了 Flash Player，则重定向到另一个域的 Javascript 代码

Question

我实际上在同一个域上有两个网站。比如说

http://www.abc.com/flashsite

&

http://www.abc.com/htmlsite

flashsite包含完全基于flash的网站，而另一个是基于html的没有flash的网站。我想要的是，如果有人访问我的网址 http://www.abc.com ，javascript应该首先检测他的浏览器中是否安装了插件。如果是，那么它应该直接带我到“flashsite”文件夹，如果不是，那么它应该默认加载 html 网站。

提前致谢。
