Hi Kikapu,
Thanks for using Microsoft Managed Newsgroup.
Vadym's direction is accurate. The http response header need to be
implemented by yourself.
For now, I want to provide a more direct way for you.
The following code snippet that I had found from internet is used to setup
a web server and I would like to share it with you:
//////////webserver.cs//////////////////
using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading ;
class MyWebServer
{
private TcpListener myListener ;
private int port = 8080 ;
public MyWebServer()
{
try
{
myListener = new TcpListener(port) ;
myListener.Start();
Console.WriteLine("Web Server Running... Press ^C to Stop...");
Thread th = new Thread(new ThreadStart(StartListen));
th.Start() ;
}
catch(Exception e)
{
Console.WriteLine("Error:" +e.ToString());
}
}
public void SendHeader(string sHttpVersion, string sMIMEHeader, int
iTotBytes, string sStatusCode, ref Socket mySocket)
{
String sBuffer = "";
if (sMIMEHeader.Length == 0 )
{
sMIMEHeader = "text/html"; // default text/html
}
sBuffer = sBuffer + sHttpVersion + sStatusCode + "\r\n";
sBuffer = sBuffer + "Server: cx1193719-b\r\n";
sBuffer = sBuffer + "Content-Type: " + sMIMEHeader + "\r\n";
sBuffer = sBuffer + "Accept-Ranges: bytes\r\n";
sBuffer = sBuffer + "Content-Length: " + iTotBytes + "\r\n\r\n";
Byte[] bSendData = Encoding.ASCII.GetBytes(sBuffer);
SendToBrowser( bSendData, ref mySocket);
Console.WriteLine("Total Bytes : " + iTotBytes.ToString());
}
public void SendToBrowser(String sData, ref Socket mySocket)
{
SendToBrowser (Encoding.ASCII.GetBytes(sData), ref mySocket);
}

if (( numBytes = mySocket.Send(bSendData, bSendData.Length,0)) == -1)
Console.WriteLine("Socket Error cannot Send Packet");

{
Console.WriteLine("No. of bytes send {0}" , numBytes);
}
}

Hope this helpful.
