websocket 如何兼容低版本浏览器？

Question

[WebSocket] debug enabled
[WebSocket] policy file: xmlsocket://211.95.3.194:843
[WebSocket] cannot connect to Web Socket server at ws://211.95.3.194:11113/demo01/MyHtml.html?message_to=&message_me= (SecurityError: Error #2048)
make sure the server is running and Flash socket policy file is correctly placed
[WebSocket] closed

我从网上下载了很多demo 大致都是flash+websocket.js+WebSocketMain.swf但为什么总是出这个错？

Answer 1

websocket是html5新增加的一种通信协议，低版本的浏览器不支持。
