1、IIS下301設置
Internet信息服務管理器 -> 虛擬目錄 -> 重定向到URL，輸入需要轉向的目標URL，並選擇“資源的永久重定向”。
2、ASP下的301轉向代碼
<%@ Language=VBScript %>
<%
Response.Status=”301 Moved Permanently”
Response.AddHeader “Location”, “http://www.lesishu.cn/articles/301/”
%>
3、ASP.Net下的301轉向代碼
<script runat=”server”>
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = “301 Moved Permanently”;
Response.AddHeader(”Location”,”http://www.lesishu.cn/articles/301/“);
}
</script>
4、PHP下的301轉向代碼
header(”HTTP/1.1 301 Moved Permanently”);
header(”Location: http://www.lesishu.cn/articles/301/”);
exit();
5、CGI Perl下的301轉向代碼
$q = new CGI;
print $q->redirect(”http://www.new-url.com/”);
6、JSP下的301轉向代碼
<%
response.setStatus(301);
response.setHeader( “Location”, “http://www.lesishu.cn/” );
response.setHeader( “Connection”, “close” );
%>
7、Apache下301轉向代碼
新建.htaccess文件，輸入下列內容（需要開啓mod_rewrite）：
1）將不帶WWW的域名轉向到帶WWW的域名下
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^lesishu.cn [NC]
RewriteRule ^(.*)$ http://www.lesishu.cn/$1 [L,R=301]
2）重定向到新域名
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*)$ http://www.lesishu.cn/$1 [L,R=301]
3）使用正則進行301轉向，實現僞靜態
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^news-(.+)\.html$ news.php?id=$1
將news.php?id=123這樣的地址轉向到news-123.html
8、Apache下vhosts.conf中配置301轉向
爲實現URL規範化，SEO通常將不帶WWW的域名轉向到帶WWW域名，vhosts.conf中配置爲：
<VirtualHost *:80>
ServerName www.lesishu.cn
DocumentRoot /home/lesishu
</VirtualHost><VirtualHost *:80>
ServerName lesishu.cn
RedirectMatch permanent ^/(.*) http://www.lesishu.cn/$1
</VirtualHost>
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName dressilyme.com
ServerAlias 192.168.1.214 *.dressilyme.com
DirectoryIndex index.html index.php
RedirectMatch permanent ^/(.*) http://www.dressilyme.com/$1
</VirtualHost>
