一个RewriteRule匹配了，却不起作用，极度不解中...

RewriteRule ^(.*)/([A-Z])([^/]+)/([^/]+)/$ http://www.google.com
测试的 url:http://127.0.0.1:8008/BeiJing/FangChan/
提示：这个url和上面那个规则是匹配的，而且放在.htaccess所有规则的最上面．既然匹配了，那访问这个url时就要转到http://www.google.com，但是浏览器返回的是下面的错误信息：

Not Found
The requested URL /BeiJing/FangChan/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.0.63 (Win32) PHP/5.2.14 Server at 127.0.0.1 Port 8008

#source url can not contain the host address!
