hdr_beg([<name>[,<occ>]]) : prefix match 前缀匹配:
acl host_www hdr_beg(host) -i www
acl host_static hdr_beg(host) -i img. video. download. ftp.

用于测试请求报文的指定首部的开头部分是否符合<string>指定的模式。例如，下面的例子用记测试请求是否为提供静态内容的主机img、video、download或ftp。
acl host_static hdr_beg(host) -i img. video. download. ftp.
acl is_a hdr_beg(host) -i www.abc.test1 #判断域名是不是www.abc.test1,是则给与a服务器集群服务
acl is_b hdr_beg(host) -i www.abc.test2 #判断域名是不是www.abc.test2,是则给与a服务器集群服务
use_backend a_server if is_a
