1、IIS下301設(shè)置

Internet信息服務(wù)管理器 -> 虛擬目錄 -> 重定向到URL，輸入需要轉(zhuǎn)向的目標(biāo)URL，并選擇“資源的永久重定向”。

2、ASP下的301轉(zhuǎn)向代碼

<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently"
Response.AddHeader "Location", "http://www./articles/301/"
%>

3、ASP.Net下的301轉(zhuǎn)向代碼

{
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","http://www./articles/301/");
}

4、PHP下的301轉(zhuǎn)向代碼

exit();

5、CGI Perl下的301轉(zhuǎn)向代碼

7、Apache下301轉(zhuǎn)向代碼

新建.htaccess文件，輸入下列內(nèi)容（需要開啟mod_rewrite）：

1）將不帶WWW的域名轉(zhuǎn)向到帶WWW的域名下

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^ [NC]
RewriteRule ^(.*)$ http://www./$1 [L,R=301]

2）重定向到新域名

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*)$ http://www./$1 [L,R=301]

3）使用正則進(jìn)行301轉(zhuǎn)向，實(shí)現(xiàn)偽靜態(tài)

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^news-(.+).html$ news.php?id=$1

將news.php?id=123這樣的地址轉(zhuǎn)向到news-123.html

8、Apache下vhosts.conf中配置301轉(zhuǎn)向

為實(shí)現(xiàn)URL規(guī)范化，SEO通常將不帶WWW的域名轉(zhuǎn)向到帶WWW域名，vhosts.conf中配置為：

<VirtualHost *:80>
ServerName www.
DocumentRoot /home/lesishu
</VirtualHost>

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

Apache下除了以上2種方法，還有其他配置方法和可選參數(shù)，建議閱讀Apache文檔。
