的.htaccess重写规则语法

Question

我需要做一些重写规则列入的.htaccess符合下列条件：

(www).site.com/setup --> redirects to: www.site.com/setup 
demo.site.com/setup --> redirects to: www.site.com/demo/setup 
(www).site.com/xyz --> redirects to: www.site.com/web/xyz 
demo.site.com/xyz --> redirects to: www.site.com/demo/web/xyz 

注意（WWW）意味着用户可以输入和没有输入www和“XYZ”可以是任何字符串，但与关键字“setup”不同（由于前两条规则）。

这是我尝试（使用[L]，使例外），但我不知道这是否是好的就够了：

RewriteCond ${REQUEST_URI} demo. 
RewriteCond ${REQUEST_URI} /setup 
RewriteRule /demo/setup [L] 

RewriteCond %{HTTP_HOST} !^www\. 
RewriteCond ${REQUEST_URI} /setup 
RewriteRule /setup [L] 

RewriteCond ${REQUEST_URI} demo. 
RewriteRule ^/(.*)$ www.site.com/demo/web/$1 [L] 

RewriteCond %{HTTP_HOST} !^www\. 
RewriteRule ^/(.*)$ www.site.com/web/$1 [L] 

任何想法？

启用mod_rewrite的，并通过httpd.conf的.htaccess，然后把这个代码在你.htaccess下DOCUMENT_ROOT目录：

Options +FollowSymLinks -MultiViews 
# Turn mod_rewrite on 
RewriteEngine On 
RewriteBase/

RewriteCond %{HTTP_HOST} ^(demo)\.(.+)$ [NC] 
RewriteRule ^(setup)/?$ http://www.%2/%1/$1 [L,R=301,NC] 

RewriteCond %{HTTP_HOST} ^(demo)\.(.+)$ [NC] 
RewriteRule ^(xyz)/?$ http://www.%2/%1/web/$1 [L,R=301,NC] 

RewriteCond %{HTTP_HOST} !^demo\. [NC] 
RewriteRule ^(xyz)/?$ /web/$1 [L,R=301,NC]
