 RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]

 RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]

二、重定向www.domain.com到domain.com

RewriteEngine On

 RewriteCond %{HTTP_HOST} !^domain.com$ [NC]

 RewriteRule ^(.*)$ http://domain.com/$1 [L,R=301]

三、重定向旧域名olddomain.com到新域名www.newdomain.com

RewriteEngine On

 RewriteCond %{HTTP_HOST} !olddomain.com$ [NC]

 RewriteRule ^(.*)$ http://www.newdomain.com/$1 [L,R=301]

四、重定向旧域名olddomain.com 到新域名newdomain.com

 RewriteBase /

 RewriteCond %{HTTP_HOST} ^olddomain.com$ [NC]

 RewriteRule ^(.*)$ http://newdomain.com/$1 [L,R=301]
