适用情形：

• 网站被托管在shared hosting里，没有独立IP
• 网站使用Cloudflare进行加速，但出于某些原因，现在需要绕过Cloudflare直接访问
• 无法通过 curl http://127.0.0.1:xxx/ 访问，无法通过 curl http://内网IP:xxx/ 访问

$ curl --header 'Host:yourDomain.com' http://公网IP:80/

（这条命令或者对应的程序最好在shared hosting本机上运行，否则还不如使用域名访问。）

用途举例：绕过Cloudflare，让缓存相关的preload更加稳定高效。
