Response.Redirect在新窗口打開的另一種方法

這里介紹Ihttpmodule處理請(qǐng)求管道的方法。Response.Redirect的原理是服務(wù)器設(shè)置返回http狀態(tài)碼為302,然后客戶端執(zhí)行跳轉(zhuǎn)，用reflector可以看到.net的代碼段。
    以下是HttpResponse類的Redirect方法中的跳轉(zhuǎn)代碼
    this.StatusCode = 0x12e;
    this.RedirectLocation = url;
    所以，我們可以擴(kuò)展Ihttpmodule來攔截http狀態(tài)碼，強(qiáng)制設(shè)為200，同時(shí)插入js代碼段來實(shí)現(xiàn)新窗口打開。以下是Ihttpmodule的實(shí)現(xiàn)代碼
    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Web;
    namespace ClassLibrary2
    ...{
    public class Class1:System.Web.IHttpModule
    ...{
    public void Init(HttpApplication application)
    ...{
    application.PreSendRequestHeaders += new EventHandler(application_PreSendRequestHeaders);
    }
    void application_PreSendRequestHeaders(object sender, EventArgs e)
    ...{
    HttpApplication Application = (HttpApplication)sender;
    HttpContext context = Application.Context;
    if (context.Response.StatusCode == 302)
    ...{
    context.Response.Write("");
    context.Response.StatusCode = 200;
    }
    }
    public　void Dispose()
    ...{
    }
    }
    }
    最后配置一下web.config就可以了
    
    
    
    
    
    
    
    
    
    this.Write("
     ");
    this.Write("Object moved to here.
     ");
    this.Write("
     ");
