301,301转向代码合集

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.yangkun.net/articles/301/”
%>

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://www.yangkun.net/articles/301/”);
}
</script>

4、PHP下的301转向代码

header(“HTTP/1.1 301 Moved Permanently”);
header(“Location: http://www.yangkun.net/articles/301/”);
exit();

5、CGI Perl下的301转向代码

$q = new CGI;
print $q->redirect(“http://www.yangkun.net/”); 

6、JSP下的301转向代码

<%
response.setStatus(301);
response.setHeader( “Location”, “http://www.yangkun.net/” );
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 +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^lesishu.com [NC]
RewriteRule ^(.*)$ http://www.yangkun.net/$1 [L,R=301]

2)重定向到新域名

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*)$ http://www.yangkun.net/$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

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.yangkun.net
DocumentRoot /home/yangkun
</VirtualHost>

<VirtualHost *:80>
ServerName yangkun.net
RedirectMatch permanent ^/(.*) http://www.yangkun.net/$1
</VirtualHost>
