直接在Global.asax.cs中操作无效,不知何原因,如下:

 protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
        {
            //HttpApplication app = sender as HttpApplication;
            //if (app != null && app.Context != null)
            //{
            //   app.Context. Response.Headers.Remove("Server");
            //    app.Context.Response.Headers.Remove("X-Powered-By");
            //    // Response.Headers.Set("Server", "ooosss");
            //    // Response.AddHeader("Sample1", "Value1");
            //}
        }

 

经测试,按上面的链接,再写一个modle可以:

 public class mysvr : IHttpModule
    {
        public void Dispose()
        {
            //no code nescessary
        }

        public void Init(HttpApplication context)
        {
            context.PreSendRequestHeaders += new EventHandler(context_PreSendRequestHeaders);
        }

        void context_PreSendRequestHeaders(object sender, EventArgs e)
        {
            try
            {
                HttpApplication app = sender as HttpApplication;
                if (null != app && null != app.Request && !app.Request.IsLocal && null != app.Context && null != app.Context.Response)
                {
                    var headers = app.Context.Response.Headers;
                    if (null != headers)
                    {
                        headers.Remove("Server");
                        headers.Remove("X-Powered-By"); //这一条无效,需要在web.config中配置去除X-Powered-By
                    }
                }
            }
            catch (Exception ex)
            {
                //   Log.HandleException(ex);
            }

        }
    }

 

以下是web.config


<configuration>
    <system.web>
      <compilation debug="true" targetFramework="4.0" />
      <httpRuntime enableVersionHeader="false" />
    </system.web>


  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <!--去除 X-Powered-By 头部信息 -->
        <clear/>
      </customHeaders>
    </httpProtocol>

    <security>
      <!-- 去除 Server 头部信息-->
      <requestFiltering removeServerHeader="true" />
    </security>

    <modules>
      <add name="mysvr" type="WebApplication2.mysvr, WebApplication2"/>  这引用前面写的module
    </modules>
    
 
    
  </system.webServer>
 
</configuration>
