mod从.domain重写为www.domain htaccess

Question

如何扩展 htaccess 文件以执行 .domain.com -> www.domain.com？

  <IfModule mod_rewrite.c>
        RewriteEngine On
        #catch potential subpages first
        RewriteRule ^([a-z-]+)/([0-9a-z-]+)/?$ index.php?page=$1&subpage=$2 [L,NC,QSA]
        #catch parent page without subpage
        RewriteRule ^([a-z-]+)/?$ index.php?page=$1 [L,NC,QSA]
  </IfModule>

是否可以不定义 domain.com？并且有任何域的通用规则？

通常我会这样做：

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

但是我如何将它与上面的指令结合起来呢？

Answer 1

有这样的规则：

RewriteEngine On

# anything.com to www.anything.com
RewriteCond %{HTTP_HOST} ^[^.]+(\.[^.]+)?$ [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301,NE]

#catch potential subpages first
RewriteRule ^([a-z-]+)/([0-9a-z-]+)/?$ index.php?page=$1&subpage=$2 [L,NC,QSA]

#catch parent page without subpage
RewriteRule ^([a-z-]+)/?$ index.php?page=$1 [L,NC,QSA]

PS：如果您还想为子域添加www，请使用此规则：

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