CI框架在nginx下rewrite的问题

hao3721

各位好，我用了CI框架，现有个需求想将

xxxx.com/game/info/28  替换成  xxxx.com/game/28.html
附本人的nginx.conf如下：
server
{
   listen 80;
   server_name xxxx.com;
   index index.html index.htm index.php default.html default.htm default.php;
   root /mnt/hgfs/xxxx.com;

   location ~ [^/]\.php(/|$)
     {
       try_files $uri =404;
       fastcgi_pass unix:/tmp/php-cgi.sock;
       fastcgi_index index.php;
       include fastcgi.conf;
       #include pathinfo.conf;
     }

   if (!-f $request_filename) {
     rewrite . /index.php last;
   }

   location ~*  /game/index{
        rewrite  /game/(\d*?).html  /index.php/game/index/$1   last;
   }

   location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
     {
       expires 30d;
     }
   location ~ .*\.(js|css)?$
     {
       expires 12h;
     }
   access_log /home/wwwlogs/$server_name  access;
}

请问哪里不正确呢？应该怎么改正？谢谢！
