websocket的全完全解决方案（兼容ie9）

1、客户端的页面用下面这个地址，运行sample

2、服务器端用下面这个即可

3、按照上面的步骤还不能支持ie9
要执行下面这个服务，拷贝下面的代码，生成一个控制台程序，然后在服务器端执行着

在Adobe Flash Player升级到9.0.124后，由于安全策略的更改，使得在socket或xmlsocket的应用里，原先如用http方式加载安全策略的手段不能继续使用了，类似此类应用必须使用xmlsocket://方式来提供安全策略。flashplayer的安全策略检测过程如下：

1,首先检测目标服务器的843端口是否提供安全策略

2,如果1没有检测到策略，则检测actionscript是否使用了

Security.loadPolicyFile(xmlsocket://)

手段提供安全策略，如果还没检测到，则使用第3步检测

3,检测目标服务器目标端口是否提供安全策略
