之前一直以為Response.Redirect （“default1.aspx”）的運(yùn)行原理是這樣的

創(chuàng)新互聯(lián)主要業(yè)務(wù)有網(wǎng)站營(yíng)銷策劃、網(wǎng)站制作、成都網(wǎng)站制作、微信公眾號(hào)開(kāi)發(fā)、微信小程序開(kāi)發(fā)、HTML5建站、程序開(kāi)發(fā)等業(yè)務(wù)。一次合作終身朋友，是我們奉行的宗旨；我們不僅僅把客戶當(dāng)客戶，還把客戶視為我們的合作伙伴，在開(kāi)展業(yè)務(wù)的過(guò)程中，公司還積累了豐富的行業(yè)經(jīng)驗(yàn)、成都全網(wǎng)營(yíng)銷推廣資源和合作伙伴關(guān)系資源，并逐漸建立起規(guī)范的客戶服務(wù)和保障體系。 

但經(jīng)過(guò)斷點(diǎn)測(cè)試發(fā)現(xiàn)不是，當(dāng)程序執(zhí)行到Response.Redirect （“default1.aspx”）；時(shí) 下邊會(huì)跳轉(zhuǎn)到default1.aspx下的Page_Load（）方法中。也就是說(shuō)2，3根本沒(méi)有運(yùn)行，只有1跟4，瀏覽器在根據(jù)4返回的狀態(tài)碼來(lái)在前臺(tái)地址欄顯示出不同的url，說(shuō)到這里了 咱們就反編譯一把Response.Redirect看看里面的具體實(shí)現(xiàn)：

internalvoidRedirect(string url, bool endResponse, bool permanent)
{
    if (url == null)
    {
        thrownewArgumentNullException("url");
    }
    if (url.IndexOf('\n') >= 0)
    {
        thrownewArgumentException(SR.GetString("Cannot_redirect_to_newline"));
    }
    if (this._headersWritten)
    {
        thrownewHttpException(SR.GetString("Cannot_redirect_after_headers_sent"));
    }
    Pagepage = this._context.HandlerasPage;
    if ((page != null) && page.IsCallback)
    {
        thrownewApplicationException(SR.GetString("Redirect_not_allowed_in_callback"));
    }
    url = this.ApplyRedirectQueryStringIfRequired(url);
    url = this.ApplyAppPathModifier(url);
    url = this.ConvertToFullyQualifiedRedirectUrlIfRequired(url);
    url = this.UrlEncodeRedirect(url);
    this.Clear();
    if (((page != null) && page.IsPostBack) && (page.SmartNavigation && (this.Request["__smartNavPostBack"] == "true")))
    {
        this.Write("");
        this.Write("");
    }
    else
    {
        this.StatusCode = permanent ? 0x12d : 0x12e;
        this.RedirectLocation = url;
        if (UriUtil.IsSafeScheme(url))
        {
            url = HttpUtility.HtmlAttributeEncode(url);
        }
        else
        {
            url = HttpUtility.HtmlAttributeEncode(HttpUtility.UrlEncode(url));
        }
        this.Write("\r\n");
        this.Write("
Object moved to here.
\r\n");
        this.Write("\r\n");
    }
    this._isRequestBeingRedirected = true;
    EventHandlerredirecting = Redirecting;
    if (redirecting != null)
    {
        redirecting(this, EventArgs.Empty);
    }
    if (endResponse)
    {
        this.End();
    }
}

其中由37，38行的

可以看出狀態(tài)碼和跳轉(zhuǎn)地址是在這里賦值的，我邪惡的感覺(jué)到擴(kuò)展IhttpModule可以攔截http狀態(tài)碼，使用js代碼段來(lái)實(shí)現(xiàn)http頁(yè)面的跳轉(zhuǎn)，代碼如下：

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);
        }
        private 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;
            }
        }
    }
}
　　

然后再配置一下web.config
