ASP.NET中实现301重定向的代码如下:
Response.Status = “301 Moved Permanently”;
Response.AddHeader(”Location”,"http://www.wecanwecan.com");
}
我封装在一个类里：
using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI;
using System.Web.UI.HTMLControls;
namespace ClassLib
{
public class URLClass
{
private bool flag301 = false;//是否启动 301
private bool isIndex = false;//是否 返回主页 或者保留在当前页
/// <summary>
/// 构造函数
/// </summary>
/// <param name="fl">是否启动 301</param>
/// <param name="page">Page</param>
/// <param name="strURL">格式www.xxx.com</param>
public URLClass(bool fl, Page page, string strURL)
{
flag301 = fl;
URL301(page, strURL);
}
/// <summary>
/// 返回主页
/// </summary>
/// <param name="page"></param>
/// <param name="strURL">格式www.xxx.com</param>
public void URL301(Page page, string strURL)
{
//301重定向
if (page.Request.Url.DnsSafeHost != strURL && flag301 == true)
{
page.Response.Clear();
page.Response.StatusCode = 301;
page.Response.Status = "301 MovedPermanently";
page.Response.AddHeader("Location", "http://" + strURL);
page.Response.End();
}
}
}
}
