Https 奇怪的行为

我在两个

https

web服务器后面有一个HAProxy

https://domain1 is proxied to backend A.
https://domain2 is proxied to backend B.

这是配置文件：

global   
    log         127.0.0.1 local2
    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon

    # turn on stats unix socket
    stats socket /var/lib/haproxy/stats
defaults
    mode                    http
    log                     global
    option                  dontlognull
    option http-server-close
    option                  redispatch
    retries                 3
    timeout http-request    10s
    timeout queue           1m
    timeout connect         10s
    timeout check           10s
    maxconn                 3000
frontend http-in
        bind *:80
        redirect scheme https code 301 if { hdr_end(host) -i domain1 } !{ ssl_fc }

frontend  www-https
    mode tcp
    bind *:443
    reqadd X-Forwarded-Proto:\ https
    tcp-request inspect-delay 5s
    tcp-request content accept if { req_ssl_hello_type 1 }
    use_backend perseo_cluster if { req_ssl_sni -i domain1  }
    use_backend octopus_cluster if { req_ssl_sni -i domain2 }
    acl is_websocket hdr(Upgrade) -i WebSocket
    use_backend wsServers if is_websocket
    default_backend             perseo_cluster

backend wsServers
 mode tcp
 server  main  10.7.246.12:8884 check
backend octopus_cluster
  mode tcp
  stick-table type binary len 32 size 30k expire 30m
  acl clienthello req_ssl_hello_type 1
  acl serverhello rep_ssl_hello_type 2
  # use tcp content accepts to detects ssl client and server hello.
  tcp-request inspect-delay 5s
  tcp-request content accept if clienthello
  # no timeout on response inspect delay by default.
  tcp-response content accept if serverhello
  stick on payload_lv(43,1) if clienthello
  # Learn on response if server hello.
  stick store-response payload_lv(43,1) if serverhello
  option ssl-hello-chk
  server  main  10.7.246.12:443 check

#---------------------------------------------------------------------
# round robin balancing between the various backends
#---------------------------------------------------------------------
backend perseo_cluster
    mode tcp
    stick-table type binary len 32 size 30k expire 30m
    acl clienthello req_ssl_hello_type 1
    acl serverhello rep_ssl_hello_type 2
    # use tcp content accepts to detects ssl client and server hello.
    tcp-request inspect-delay 5s
    tcp-request content accept if clienthello
    # no timeout on response inspect delay by default.
    tcp-response content accept if serverhello
    stick on payload_lv(43,1) if clienthello
    # Learn on response if server hello.
    stick store-response payload_lv(43,1) if serverhello
    option ssl-hello-chk
    server stn_perseo 10.0.0.15:443

然而，有时，虽然url指向B，但结果是a的响应，显然是“未找到”。 我的HAProxy版本是：

# haproxy -v
HA-Proxy version 1.5.4 2014/09/02

也许超时时间太少了

使用haproxy-v检查您的版本。此配置文件不可能与HAProxy 1.4.x一起使用，因此我们需要确定您正在运行的实际版本1.x.yy。抱歉，我重新检查了它。它是1.5.4
