怎样才能给我的Joomla网站上添加上“www”前缀呢？
添加如下内容到你的.htaccess文件中：
RewriteEngine On
RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$
RewriteRule (.*) http://www.example.com/$1 [R=301,L]同时针对于纠正网址指向错误的较完整的解决方案：
RewriteEngine On
#
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.html?\ HTTP/
RewriteRule ^(([^/]+/)*)index\.html?$ http://www.example.com/$1 [R=301,L]
#
RewriteCond %{THE_REQUEST} !^POST
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.php\ HTTP/
RewriteCond %{SERVER_PORT}>s ^(443>(s)|[0-9]+>s)$
RewriteRule ^(([^/]+/)*)index\.php$ http%2://www.example.com/$1 [R=301,L]
#
RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
