Answer 1

Add this to your global.asax.cs:

protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
{
    // Remove the "Server" HTTP Header from response
    HttpApplication app = sender as HttpApplication;
    if (null != app && null != app.Request && !app.Request.IsLocal &&
        null != app.Context && null != app.Context.Response)
    {
        NameValueCollection headers = app.Context.Response.Headers;
        if (null != headers)
        {
            headers.Remove("Server");
        }
    }
}
