HttpListener Server Header c#

I am trying to write a C# http server for a personal project, i am wondering how i can change the returned server header from Microsoft-HTTPAPI/2.0, to something else?

 public class HttpWebServer
    {
        private HttpListener Listener;

        public void Start()
        {
            Listener = new HttpListener();
            Listener.Prefixes.Add("http://*:5555/");
            Listener.Start();
            Listener.BeginGetContext(ProcessRequest, Listener);
            Console.WriteLine("Connection Started");
        }

        public void Stop()
        {
            Listener.Stop();
        }

        private void ProcessRequest(IAsyncResult result)
        {
            HttpListener listener = (HttpListener)result.AsyncState;
            HttpListenerContext context = listener.EndGetContext(result);

            string responseString = "<html>Hello World</html>";
            byte[] buffer = Encoding.UTF8.GetBytes(responseString);

            context.Response.ContentLength64 = buffer.Length;
            System.IO.Stream output = context.Response.OutputStream;
            output.Write(buffer, 0, buffer.Length);
            output.Close();

            Listener.BeginGetContext(ProcessRequest, Listener);
        }
    }

The following line should do the trick:

context.Response.Headers.Set(HttpResponseHeader.Server, "My Personal Server");

for a complete list of response headers you can set see: HttpResponseHeader Enumeration

It should but it doesn't.

Hi arul,

I did try, but it comes back with My Personal Server Microsoft-HTTPAPI/2.0

I have also used with no success, set, remove, add, addheader

private void ProcessRequest(IAsyncResult result)
        {
            HttpListener listener = (HttpListener)result.AsyncState;
            HttpListenerContext context = listener.EndGetContext(result);

            string responseString = "<html>Hello World</html>";
            byte[] buffer = Encoding.UTF8.GetBytes(responseString);
            context.Response.ContentLength64 = buffer.Length;

            //One
            context.Response.AddHeader("Server", "My Personal Server");

            //Two
            context.Response.Headers.Remove(HttpResponseHeader.Server);
            context.Response.Headers.Add(HttpResponseHeader.Server, "My Personal Server");

            //Three
            context.Response.Headers.Set(HttpResponseHeader.Server, "My Personal Server");

            System.IO.Stream output = context.Response.OutputStream;
            output.Write(buffer, 0, buffer.Length);
            output.Close();

            Listener.BeginGetContext(ProcessRequest, Listener);
        }

Thanks Elijah

Could you update the original code, please?

+4  A: 

The HttpListener class encapsulates the native API, HttpSendHttpResponse Function, which as stated in the link will always append the preposterous text to the server header information.

There's no way how to fix that, unless you want to code your HttpListener from scratch.
