强迫非www到htaccess中的www

Question

我有：

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

但它不起作用。我仍然可以访问www和非www版本。我做错了什么？

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]
