nginx的cache功能不能用，请高手出手！！！

我的配置文件如下：

[root@localhost nginx]# cat nginx.conf

user nginx nginx;

worker_processes 8;

error_log  /app/nginx/logs/nginx_error.log  crit;

pid /app/nginx/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

events
{
  use epoll;
  worker_connections 65535;
}

http
{
  include    mime.types;
  default_type  application/octet-stream;

  charset  utf-8;

  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 300m;

  sendfile on;
  tcp_nopush    on;

  keepalive_timeout 60;

  tcp_nodelay on;

  client_body_buffer_size  512k;
  proxy_connect_timeout 5;
  proxy_read_timeout    60;
  proxy_send_timeout    5;
  proxy_buffer_size       16k;
  proxy_buffers          4 64k;
  proxy_busy_buffers_size 128k;
  proxy_temp_file_write_size 128k;

  gzip on;

  upstream backend_server {

  }

  server

      proxy_pass http://backend_server;
      expires    1d;
}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css|html)$
{

      proxy_cache cache_one;

      proxy_set_header X-Forwarded-For  $remote_addr;
      proxy_pass http://backend_server;

}

location ~ /purge(/.*)
{
   allow          127.0.0.1;
   allow          192.168.0.0/16;
   deny          all;
   proxy_cache_purge cache_one $host$1$is_args$args;
}

location ~ .*\.(jsp|cgi)?$
{
      proxy_set_header Host  $host;
      proxy_set_header X-Forwarded-For  $remote_addr;
      proxy_pass http://backend_server;
}

access_log  off;
  }
}

我访问 backend_server上的图片，在/app/cache/proxy_cache 下去没任何cache , /app/cache/proxy_cache 目录权限是777, 用户是nginx. 请高手指点。
