如何使用mod ou rewrite来更改根据URL的子域提取的文件?

在sub.domain的httpd配置中:

RewriteCond %{HTTP_HOST} ([^\.]+).domain
RewriteRule ^/file.bin$ http://domain/hosted/%1/file.bin

假设主目录 www.domain.com 是 domain/ 并且-给定任何子域 sub.domain.com -您希望该子域的主目录的文件位于 domain/hosted/sub/

尝试如下操作:

RewriteEngine on

// If the host is just mydomain.com, do nothing more
// this is to prevent some recursion problems I've read of...
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$ [NC]
RewriteRule ^.*$ - [L]

// Otherwise strip off everything before mydomain
// And add it to the start of the request
RewriteCond %{HTTP_HOST} ^(.*?)\.(www\.)?mydomain\.com$ [NC]
RewriteRule ^.*$ %1%{REQUEST_URI} [QSA]

// Then prefix with 'hosted'
RewriteRule ^(.*)$ hosted/$1 [QSA,L]

您可能还需要在DNS中输入通配符或其他…但是我承认dns和htaccess mod rewrite是我的弱点。也见 http://www.webmasterworld.com/forum92/138.htm

试试这个规则:

RewriteCond %{HTTP_HOST} ^([^/.]+)\.example\.com$
RewriteCond %1 !=www
RewriteRule !^hosted/ hosted/%1%{REQUEST_URI} [L]
