Unwanted info:

X-AspNet-Version 4.0.303319
X-Powered-By ASP.NET

1. Removing X-AspNet-Version

In web.config stick this line in

<system.web>
      <httpRuntime enableVersionHeader="false"/>
	...

2. Removing X-AspNetMvc-Version

In Global.asax.cs add this line:

protected void Application_Start()
{
    MvcHandler.DisableMvcResponseHeader = true;
}

3. Removing or changing Server

Add this module class to your project.

using System;
using System.Web;

namespace Project.Infrastructure.Web.Modules.Http
{
    public class CustomHeaderModule : IHttpModule
    {
        public void Init(HttpApplication context)
        {
            context.PreSendRequestHeaders += OnPreSendRequestHeaders;
        }

        public void Dispose() { }

        void OnPreSendRequestHeaders(object sender, EventArgs e)
        {
	     //HttpContext.Current.Response.Headers.Remove("Server");
            // Or you can set something funny
	    HttpContext.Current.Response.Headers.Set("Server", "CERN httpd");
        }
    }
}

And add set it in web config

	<system.webServer>
		<modules>
        <add name="CustomHeaderModule" type="StrongNamespace.HttpModules.CustomHeaderModule" />
