默认情况下,每一个MVC请求的HTTP Header中都会包含着当前服务器的一些信息,出于安全还是性能还是处女座的强迫症等等,都想把这些信息移除掉,增加一些应用程序的神秘感,如下,默认情况下Chrome中截获的HTTP Header信息:

Cache-Control:private, s-maxage=0
Content-Encoding:gzip
Content-Length:1184
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Oct 2017 05:01:37 GMT
Server:Microsoft-IIS/10.0
Vary:Accept-Encoding
X-AspNet-Version:4.0.30319
X-AspNetMvc-Version:5.2
X-Powered-By:ASP.NET
X-SourceFiles:=?UTF-8?B?RTpcV29ya1xUaWFuTG9uZ1xMUS5NVkNBZG1pblxNYW5hZ2VyXEVxdWlwbWVudHM=?=

接下来,一步一步的移除其中的一些信息,本文环境为.NET Framework 4.5、MVC 5、IIS 10,测试有效。

移除X-AspNetMvc-Version

在Global.asax.cs中添加如下代码:

protected void Application_Start()
        {
            //屏蔽浏览器中的ASP.NET版本
            MvcHandler.DisableMvcResponseHeader = true;

            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }

效果如下:

Cache-Control:private, s-maxage=0
Content-Encoding:gzip
Content-Length:1184
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Oct 2017 05:03:57 GMT
Server:Microsoft-IIS/10.0
Vary:Accept-Encoding
X-AspNet-Version:4.0.30319
X-Powered-By:ASP.NET
X-SourceFiles:=?UTF-8?B?RTpcV29ya1xUaWFuTG9uZ1xMUS5NVkNBZG1pblxNYW5hZ2VyXEVxdWlwbWVudHM=?=

移除X-AspNet-Version

在config中添加如下代码:

<system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" enableVersionHeader="false"/>
  </system.web>

效果如下:

Cache-Control:private, s-maxage=0
Content-Encoding:gzip
Content-Length:1184
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Oct 2017 03:46:23 GMT
Vary:Accept-Encoding
Server:Microsoft-IIS/10.0
X-Powered-By:ASP.NET
X-SourceFiles:=?UTF-8?B?RTpcV29ya1xUaWFuTG9uZ1xMUS5NVkNBZG1pblxNYW5hZ2VyXEVxdWlwbWVudHM=?=

移除Server

既可以移除同时也可以修改Server信息,也可以实现上面两个信息的移除,在Global.asax.cs文件中添加如下代码

protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
        {
            HttpApplication app = sender as HttpApplication;
            if (app != null && app.Context != null)
            {
                //移除Server
                app.Context.Response.Headers.Remove("Server");
                //修改Server的值
                  //app.Context.Response.Headers.Set("Server", "MyPreciousServer");

                //移除X-AspNet-Version,和上面效果一样
                  app.Context.Response.Headers.Remove("X-AspNet-Version");

                //移除X-AspNetMvc-Version,和上面效果一样
                  app.Context.Response.Headers.Remove("X-AspNetMvc-Version");
            }
        }

效果如下:

Cache-Control:private, s-maxage=0
Content-Encoding:gzip
Content-Length:1184
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Oct 2017 05:25:00 GMT
Vary:Accept-Encoding
X-Powered-By:ASP.NET
X-SourceFiles:=?UTF-8?B?RTpcV29ya1xUaWFuTG9uZ1xMUS5NVkNBZG1pblxNYW5hZ2VyXEVxdWlwbWVudHM=?=

 

移除X-Powered-By

在webconfig中添加配置项:

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <remove name="X-Powered-By" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>

移除效果如下:

Cache-Control:private, s-maxage=0
Content-Encoding:gzip
Content-Length:1184
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Oct 2017 05:29:05 GMT
Vary:Accept-Encoding
