    <hdr>     is the name of a HTTP header in which to fetch the IP to bind to.

This is the name of a comma-separated header list which can

contain multiple IP addresses. By default, the last occurrence is

used. This is designed to work with the X-Forwarded-For header

and to automatically bind to the client’s IP address as seen

by previous proxy, typically Stunnel. In order to use another

occurrence from the last one, please see the parameter

below. When the header (or occurrence) is not found, no binding

is performed so that the proxy’s default IP address is used. Also

keep in mind that the header name is case insensitive, as for any

HTTP header.

acl monitor hdr_beg(host) -i monitor.test.com #定义ACL名称,对应的请求的主机头是monitor.test.com
