首先在Global.asax.cs里增加：

PRotected void application_PreSendRequestContent(object sender, EventArgs e)
{
HttpContext.Current.Response.Headers.Set(“Server”, “w3cnet.com”);
HttpContext.Current.Response.Headers.Remove(“X-aspNet-Version”);
HttpContext.Current.Response.Cookies.Remove(“.ASPXAUTH”);
}

然后web.config的system.webServer節點下增加：

<httpProtocol>
<customHeaders>
<remove name=”X-Powered-By” />
</customHeaders>
</httpProtocol>

再看看響應頭，或用站長工具查看，完美隱藏。
