        location ~ \.php$ {  
            root        /usr/local/sitebuilder/htdocs;  
            fastcgi_pass   fast-cgi-backend;  
            fastcgi_index  index.php;  
            fastcgi_param  SCRIPT_FILENAME  /usr/local/htdocs$fastcgi_script_name;  
            fastcgi_param   PHPRC           /usr/local/php;  
            include        conf/fastcgi_params;  
        }  
  
    upstream  fast-cgi-backend  {  
       server   127.0.0.1:1088        weight=5;  
       server   127.0.0.1:1089        max_fails=3  fail_timeout=30s;  
    }  
  
  
На опции  weight=5 и max_fails=3  fail_timeout=30s nginx ругается...  
Вообще, группу fastcgi-server'ов можно использовать?  
nginx-0.5.20  
  
Заранее благодарю.
