Tango Server:

Tango Client:
http://www.dsource.org/projects/tango/wiki/SocketHelloExample

I'm referring to these two examples.
In the server Example, I strip off the client part and it becomes 
as follow.

void main()
{
	const int port = 8080;

	// thread body for socket-listener
	void run()
	{
		auto server = new ServerSocket (new IPv4Address(port));

		// wait for requests
		auto request = server.accept;

		// write a response
		request.output.write ("server replies 'hello'");		

	}

	Cout("server started");
	while (true )
	{
		// start server in a separate thread, and wait for it to start		
		(new Thread (&run)).start;
		tango.core.Thread.thread_sleep (0.250);
	}

}

Situation:

I have my server running and I open a client in another cmd 
console window and it replied alright. But if I try to connect it 
again second time, it freezes.

Why is that? I thought the server is constantly receiving 
messages and replying,  why would it freeze up and stop 
responding? what went wrong?

please advise.

Thanks

I use thread to expedite the execution?

void main()
{
	const int port = 8080;

	auto server = new ServerSocket (new IPv4Address(port));
	Cout("server started");
	while (true )
	{
		// wait for requests
		auto request = server.accept;
		// write a response
		request.output.write ("server replies 'hello'");		
		request.close;
	}
}
