我正在尝试制作一个简单的C#网页服务器，目前您可以通过浏览器访问并只会显示“Hello World”。
我遇到的问题是，服务器可以正常接收数据 - 我可以获取浏览器的头部信息 - 但浏览器收不到我发送的任何内容。此外，我只能通过访问本地主机 (或 127.0.0.1) 来连接到服务器。我不能通过我的 IP 来连接它，也不是网络设置的问题，因为如果我运行 Apache，则可以正常工作。另外，我正在使用一个端口监控程序，在我尝试从浏览器连接之后，该进程的端口会停留在 TIME_WAIT 状态，即使我告诉连接关闭了，它应该回到 LISTEN。
这是相关的代码。有几个调用可能没有意义，但这是更大程序的一部分。
class ConnectionHandler
{
private Server server;
private TcpListener tcp;
private ArrayList connections;

{
server.log("Connection Manager: " + s, e);
}

{
while (listening)
{
try
{
TcpClient t = tcp.AcceptTcpClient();
Connection conn = new Connection(this, t);
}
catch (NullReferenceException)
{
log("unable to accept connections!", true);
}
}
log("Stopped listening", false);
}

{
log("Listening for new connections", false);
tcp.Start();

if (listeningThread != null && listeningThread.IsAlive)
{

this.threadedListen));
listeningThread.Start();

nsSend(fullMsg, ns);
nsSend(msg, ns);

}
catch (ArgumentNullException e)
{

}
catch (SocketException e)
{

}
}
private void nsSend(String s, NetworkStream ns)
{
Byte[] data = System.Text.Encoding.ASCII.GetBytes(s);
ns.Write(data, 0, data.Length);
ns.Flush();

有人有任何想法吗？感觉好像是我自己的愚蠢，但我不知道是什么。我真的很感激任何的见解。
