SQUID急救我，谢谢！！

我用squid做两个服务器的加速器模式。在浏览器敲atest.xxx.com或btest.xxx.com,无论如何都出Access Denied错,请指教到底哪里错了。
（鞠躬！）
1、配置hosts:（浏览器端hosts和主DNS都是下面这样配置的）
202.106.184.200 atest.xxx.com
202.106.186.250 btest.xxx.com
2、配置squid.conf
http_port 80
acl accel_port port 80
acl accel_host dst 202.106.184.200/255.255.255.255
acl accel_host1 dst 202.106.186.250/255.255.255.255

http_access allow accel_host
http_access allow accel_host1
http_access allow all

httpd_accel_host 202.106.184.200/255.255.255.255
httpd_accel_host 202.106.186.250/255.255.255.255
httpd_accel_port 80
