seo里的301重定向的几种使用方法

• .htaccess

RewriteCond %{HTTP_HOST} ^autoit.net [NC]
RewriteRule ^(.*)$ http://www.autoit.net/$1 [L,R=301] 

RewriteCond %{HTTP_HOST} !^autoit.net$ [NC]
RewriteRule ^(.*)$ http://autoit.net/$1 [L,R=301]  

• 单页的

Redirect 301 /default.html http://www.autoit.net/index.html 

• 站点某些目录更改后，也可以直接在php里...

<?php
Header( "HTTP/1.1 301 Moved Permanently" ); 
Header( "Location: http://www.autoit.net/" );
?>

• Apache里也可以

ServerName autoit.net
 .... 
Redirect permanent / http://www.autoit.net/ 

ServerName autoit.net
 .... 
RedirectMatch permanent ^/(.*) http://www.autoit.net/$1
