我需要使用 haproxy 来监听端口 80，如果请求与该角色匹配，则转发该请求。我这样做了，但我不知道如何判断是否使用探测器后端
frontend httpfw
bind *:80
mode http
acl # what I must write here to defend a domain like test1.com
acl # what I must write here to defend a domain like test2.com
use_backend httptest1 if # how can I told to use this backend if the request comes from test1.com
use_backend httptest2 if # how can I told to use this backend if the request come from test2.com
backend httptest1
mode http
balance source
server httptest1 1.1.1.1:80
backend httptest2
mode http
balance source
server httptest2 2.2.2.2:80
谢谢 ：）

在您提供的示例中，以下应将流量路由到相应的后端：
## Look at host header
acl host_test1 hdr(host) -i test1.com
acl host_test2 hdr(host) -i test2.com
## figure out which one to use depending on the criteria above
use_backend httptest1 if host_test1
use_backend httptest2 if host_test2
