301重定向跳转代码使用于ASP、PHP、JSP、.NET

1、IIS下301设置Internet信息服务管理器 -> 虚拟目录 -> 重定向到URL，输入需要转向的目标URL，并选择“资源的永久重定向”。

2、ASP下的301转向代码<%@ Language=VBScript %><%Response.Status=”301 Moved Permanently”Response.AddHeader “Location”, “http://www.weichuanghr.com/articles/301/”%>

3、ASP.Net下的301转向代码<script runat=”server”>private void Page_Load(o芟鲠阻缒bject sender, System.EventArgs e){Response.Status = “301 Moved Permanently”;Response.AddHeader(”Location”,”http://www.weichuanghr.com/articles/301/“);}</script>

4、PHP下的301转向代码header(”HTTP/1.1 301 Moved Permanently”);header(”Location: http://www.weichuanghr.com/articles/301/”);exit();

5、CGI Perl下的301转向代码$q = new CGI;print $q->redirect(”http://www.weichuanghr.com/”);

6、JSP下的301转向代码<%response.setStatus(301);response.setHeader( “Location”, “http://www.weichuanghr.com/” );response.setHeader( “Connection”, “close” );%>

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 +FollowSymLinksRewriteEngine onRewriteCond %{HTTP_HOST} ^lesishu.cn [NC]RewriteRule ^(.*)$ http://www.weichuanghr.com/$1 [L,R=301]2）重定向到新域名Options +FollowSymLinksRewriteEngine onRewriteRule ^(.*)$ http://www.weichuanghr.com/$1 [L,R=301]3）使用正则进行301转向，实现伪静态Options +FollowSymLinksRewriteEngine onRewriteRule ^news-(.+)\.html$ news.php?id=$1将news.php?id=123这样的地址转向到news-123.html

8、Apache下vhosts.conf中配置301转向为实现URL规范化，SEO通常将不带WWW的域名转向到带WWW域名，vhosts.conf中配置为：<VirtualHost *:80>ServerName www.weichuanghr.comDocumentRoot /home/lesishu</VirtualHost><VirtualHost *:80>ServerName lesishu.cnRedirectMatch permanent ^/(.*) http://www.weichuanghr.com/$1</VirtualHost>
