Hi,

In the network in chrome browser i have checked server vession in the response headers for some requests.

I have added below code in the global.asax file but it's not working for some requests.

I want to hide server property from response headers in all requests.

If you could help me in this, It would be appreciated.

What I have tried:

I have added below code in global.asax file in some events.

public void Init(HttpApplication app)
        {
            app.PreRequestHandlerExecute += app_PreRequestHandlerExecute;
        }
        protected void Application_PreSendRequestHeaders()
        {
            Response.Headers.Remove("Server");
            Response.Headers.Remove("X-AspNet-Version");


            Response.Headers.Remove("X-Powered-By");
            //HttpContext.Current.Response.Headers.Remove("Server");
            //Response.Headers.Set("Server", "N/A");

        }
        private void app_PreRequestHandlerExecute(object sender, EventArgs e)
        {
            try
            {
                HttpContext.Current.Response.Headers.Remove("X-Powered-By");
                HttpContext.Current.Response.Headers.Remove("X-AspNet-Version");
                HttpContext.Current.Response.Headers.Remove("Server");
                HttpContext.Current.Response.Headers.Remove("MicrosoftSharePointTeamServices");
                //Response.Headers.Set("Server", "N/A");
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
        }

Suppose in Get response it is not showing server header but in options response it is showing. Please suggest me the solution.
