301重定向,也称为301转向。它的功能就是告诉搜索引擎,你的网址永久的变换了,从而将原网址的权重全部定向到新的网址上面,相信很多人都会用到301重定向的。

<%@ Language=VBScript %> <% Response.Status=”301 Moved Permanently” Response.AddHeader “Location”, “http://jzxue.com/” %> |
3、ASP.Net下的301转向代码
<script runat=”server”> private void Page_Load(object sender, System.EventArgs e) { Response.Status = “301 Moved Permanently”; Response.AddHeader(”Location”,”http://jzxue.com/“); } </script> |

7、Apache下301转向代码
新建.htaccess文件,输入下列内容(需要开启mod_rewrite):
1)将不带WWW的域名转向到带WWW的域名下
Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^lesishu.cn [NC] RewriteRule ^(.*)$ http://jzxue.com/$1 [L,R=301] |
2)重定向到新域名
Options +FollowSymLinks RewriteEngine on RewriteRule ^(.*)$ http://jzxue.com/$1 [L,R=301] |
3)使用正则进行301转向,实现伪静态
Options +FollowSymLinks RewriteEngine on RewriteRule ^news-(.+).html$ news.php?id=$1
将news.php?id=123这样的地址转向到news-123.html
