how to remove response headers for image css and js requests

Question

I have deployed a web application

I wanted to remove the server information and i was able to achieve it in handlers by adding these lines in global.asax as suggested here

 protected void Application_BeginRequest(object sender, EventArgs e)
        {
            var application = sender as HttpApplication;
            if (application != null && application.Context != null)
            {
                application.Context.Response.Headers.Remove("Server");
            }

        }

Now this removes headers for XHR requests, but still i am able to find server information in the image request's response headers!! How to remove them?

I found another similar question here. The leading answer was to add this to your web.config:

<system.webServer>     
  <modules runAllManagedModulesForAllRequests="true">     
   </modules>     
</system.webServer>
