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 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.

I know I'm a little late but I was just recently trying to do the same thing and I accidentally came across a solution that works but I'm unsure if it has any repercussions.
Response.Headers.Add("Server", "\r\n\r\n");
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);
}
