dl.dropbox.com和dl-web.dropbox.com此类使用amazon s3服务的地址不可用

[GoogleCodeExporter]

由于s3服务上的负载均衡机制，dns解析出的地址是动态的，如
果在hosts文件中指定就有可能会错误地指向其他使用s3服务的�
��站，下面这个是指向了 *.bittorrent.com了：

You attempted to reach dl.dropbox.com, but instead you actually reached a 
server identifying itself as *.bittorrent.com. This may be caused by a 
misconfiguration on the server or by something more serious. An attacker on 
your network could be trying to get you to visit a fake (and potentially 
harmful) version of dl.dropbox.com. You should not proceed.

建议不要缓存此类使用了s3服务的域名。
