力非WWW到www htaccess的

Question

我：

# BEGIN WithoutWWW 
RewriteEngine On 
RewriteCond %{HTTP_HOST} ^mysite.com [NC] 
RewriteRule ^(.*)$ http://www.mysite.com/$1 [L,R=301] 
# END WithoutWWW 

但它不会工作。我仍然可以访问www和非www版本。我究竟做错了什么？

Answer 1

尝试：

 

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

//OR 
RewriteEngine On 
RewriteCond %{HTTP_HOST} !^www\. 
RewriteRule (.*) http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] 
 

Answer 2

RewriteEngine On 
RewriteCond %{HTTP_HOST} !^www\.mysite\.com [NC] 
RewriteRule ^(.*)$ [R=301,L]
