推荐答案

下面是部分HAProxy配置，可以为您完成此操作:

Here's a partial HAProxy configuration which can do this for you:

frontend webserver
  bind :80
  mode http
  acl is_post method POST
  use_backend post_app if is_post
  default_backend get_app

backend post_app
  mode http
  option forwardfor
  balance source
  option httpclose
  option httpchk HEAD / HTTP/1.0
  server post_app1 172.16.0.11:80 weight 1 check inter 1000 rise 5 fall 1
  server post_app2 172.16.0.12:80 weight 1 check inter 1000 rise 5 fall 1
  server post_app3 172.16.0.13:80 weight 1 check inter 1000 rise 5 fall 1 backup

backend get_app
  mode http
  option forwardfor
  balance source
  option httpclose
  option httpchk HEAD / HTTP/1.0
  server get_app1 172.16.0.21:80 weight 1 check inter 1000 rise 5 fall 1
  server get_app2 172.16.0.22:80 weight 1 check inter 1000 rise 5 fall 1
