Socket: The connection was reset

[Nrgyzer]

Hi guys,

I wrote the following few lines:

private {

        import std.socket;

}

void main() {

        Socket s = new TcpSocket();
        s.bind(new InternetAddress(80));
        s.listen(0);

        while(true) {

                Socket cs = s.accept();
                cs.sendTo("HTTP/1.1 200 OK\r\nContent-Length: 11\r\n\r\nHello 
World");
                cs.close();

        }

        s.close();

}

The code compiles successfully and I also the server also responses with "Hello 
World", but when I reload the page I sometimes get the following error 
(Firefox): "The
connection was reset" - I also often get the same error in other browsers. Is 
there anything wrong with the code?

Thanks in advance!
