泛域名url_rewrite规则参考
当访问http://health.domain.com转向到 http://www.domain.com/category/health。
rewrite rule配置如下：
RewriteEngine On
RewriteCond %{HTTP_HOST} ^[a-z0-9\-]+\.domain\.com$
RewriteRule ^/?$ /%{HTTP_HOST}
RewriteRule ^/([a-z0-9\-]+)\.domain\.com/?$ /category/$1 [R,L]
rewrite rule配置如下：
RewriteEngine On
RewriteCond %{HTTP_HOST} ^[a-z0-9\-]+\.domain\.com$
RewriteRule ^/?$ /%{HTTP_HOST}
RewriteRule ^/([a-z0-9\-]+)\.domain\.com/?$ /category/$1 [R,L]
