yaf框架的url访问问题
很早就听说了鸟哥的yaf，最近想搭一个试用研究下
但是访问遇到了一些问题：
是在lnmp环境，nginx配置是 

root  /www/web/root;
   if (!-e $request_filename) {
       rewrite ^/(.*)$ /index.php/$1 last;
   }

我直接访问domain.com/mainweb没问题，能访问到默认control  index，
但是我访问domain.com/mainweb/index/index 确是500，然后nginx错误日志是rewrite or internal redirection cycle while processing "/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/mainweb/index/index"
访问 index control中的其他action 也是500错误
------解决方案--------------------
对比一下有什么不同

server {

       listen  80;

       server_name     www.phpno.com;

       root /home/www/www_phpno_com/admin_wwwroot;

       access_log off;

       error_page 404  /404.html;

       location /404.html {

               root /home/www/www_phpno_com/admin_wwwroot;

       }

       location /{

               index index.html index.htm index.php;

               if (-e $request_filename) {

                       break;

               }

               if (!-e $request_filename) {

                       rewrite ^/(.*)$ /index.php/$1 last;

                       break;

               }

       }

 

       location ~ .+\.php($

/) {

           root           /home/www/www_phpno_com/admin_wwwroot;

           fastcgi_index index.php;

           fastcgi_split_path_info ^(.+\.php)(.*)$;

           fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;

           fastcgi_param   PATH_INFO               $fastcgi_path_info;

           fastcgi_param   PATH_TRANSLATED $document_ro
