c# socket 与 Flash XMLSocket 策略文件传输 问题，高手来~~！！
现在基本上了解了 Flash XMLSocket 的基本应用，问题在于传输的安全策略问题，一直弄不明白，望高人指点，给点源码更是感激不尽，在线等，分不够再加~！
Flash 基本源码：
socket = new XMLSocket();
socket.onConnect = function(success) {
if (success) {
trace("Connection succeeded!");
} else {
trace("Connection failed!");
}
};
socket.onClose = function(){
//
}
if (!socket.connect(null, 6500)) {
trace("connectionFailed");
} else {
trace("waitForConnection");
}
socket.onData = function(doc) {
trace("asddddddddddd=="+doc.length);
trace(doc);
};

C/C++ code

MFC定义  CString privacyXml;   privacyXml = "<cross-domain-policy>\    <allow-access-from domain=\"*\" to-ports=\"5678\" />\     </cross-domain-policy>";    if(strcmp(clientobj->RecvDataBuf.buf,"<policy-file-request/>") == 0) //请求策略文件                {                    strcpy(clientobj->RecvDataBuf.buf,privacyXml);                    SendBytes = sizeof(privacyXml);                    g_pchatserver->m_Client->optype = OP_IOWrite;                    if (WSASend(g_pchatserver->m_Client->sclient, &(g_pchatserver->m_Client->RecvDataBuf), 1, &SendBytes, 0,                        &(g_pchatserver->m_Client->ol), NULL) == SOCKET_ERROR)                    {                        if (WSAGetLastError() != ERROR_IO_PENDING)                        {                            wsprintf(errormsg,"WSASend() failed with error %d", WSAGetLastError());                            ::MessageBox(NULL,errormsg,"Error",MB_OK);                            return -1;                        }                    }                    break;                }

因为flash在和服务器通信的时候会首先连接843端口，如果连接不上flash就会寻找服务器其它在监听的端口进行连接并且发送<policy-file-request/> \0，这个时候你需要发送策略文件给flash,至于策略文件是什么，"<cross-domain-policy> "+"<allow-access-from domain=\"*\" to-ports=\"1025-9999\"/>"+"</cross-domain-policy> "+(char)0 这个字串就是策略文件的内容，你把这个字串发送给flash就可以了
