◥〓★〓◤-在线等待(QQ:9531511) 一个超难的问题，请版主予以解答或者其他有能力解决者(关于在IE中网页中嵌入.NET Windows 控件的难题)

这是一个示例程序，只是为了证明这个问题的存在性，（我怀疑这个是 Microsoft 的 Bug),这是一个嵌入在网页的Socket 通讯程序

我有两个Socket 服务器程序, 一个程序是侦听UDP 消息, 一个是侦听 TCP 消息

客户端是放在网页中的控件,注意 客户端的.NET 的安全性我已经设置成完全信任,所以应该不是安全性的问题

问题:
如果这个控件放在Web中,那么这两个客户端发送第一条消息的时候非常慢(大概2分钟后才发送成功),但是可以发送成功, 以后发送的消息就很快了!

如果这个控件放在WinForm中,发送消息很正常

代码如下:
TcpServer.cs

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace TcpServer
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
try
{
Socket server = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPEndPoint ipep = new IPEndPoint(IPAddress.Any,5200);
server.Bind(ipep);
server.Listen(10);

Console.WriteLine("服务器套接字开始侦听......");

while(true)
{
Socket Client = server.Accept();
Console.WriteLine("发现一个客户端......");
byte[] buffer = new byte[1024];
Console.WriteLine("正在接收数据......");
int recv = Client.Receive(buffer);
Console.WriteLine(Encoding.Default.GetString(buffer,0,recv));
Console.WriteLine("正在发送数据......");
Client.Send(Encoding.Default.GetBytes(DateTime.Now.ToString()));
Client.Close();
}
}
catch(Exception ex)
{
Console.WriteLine(ex.Message + "\n" + ex.StackTrace);
}
}
}
}
