將子目錄重定向到.htaccess中的子域

Question

我想使用.htaccess將子目錄重定向到子域。我目前的代碼：

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteBase/
RewriteRule ^index\.php$ - [L] 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule . /index.php [L] 
RewriteCond %{HTTP_HOST} ^(www.)?sub.example.com$ 
RewriteRule ^(/)?$ subdirectory [L] 
</IfModule> 

此代碼重定向到sub.example.com/subdirectory。如何從新網址中刪除/subdirectory？

Answer 1

將這一規則放在上面，所有其他規則之前：

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

完整的.htaccess：

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteBase/

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

RewriteCond %{HTTP_HOST} ^(www\.)?sub\.example\.com$ [NC] 
RewriteCond %{REQUEST_URI} !(jpe?g|gif|bmp|png|tiff|css|js)$ [NC] 
RewriteRule !subdirectory subdirectory%{REQUEST_URI} [NC,L] 

RewriteRule ^index\.php$ - [L] 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule . /index.php [L] 
</IfModule>
