問題

我想問一個問題，如果有人可以幫助我找到解決方案，我將不勝感激。

我使用的是 haproxy 版本 1.4.15

[root@HAProxy tmp]# haproxy -v
HA-Proxy version 1.5.14 2015/07/02

問題

但是，我遇到一個問題，它每次都會丟棄相同的 HTTP 回應，並且不會轉送回客戶端。

當以下兩個請求傳送到 HA 代理程式時，只有第二個請求的回應會傳送回客戶端。對於第一個，haproxy 正在從後端接收傳回，但在轉送到客戶端時會丟棄 200 OK。

Oct 14 14:31:17 localhost haproxy[11601]: xxx.xxx.xxx.xxx:50114 [14/Oct/2015:14:31:17.193] http-in console/Console 0/0/0/22/25 200 78668 - - --NI 1/1/0/1/0 0/0 "GET /Console/MultiLanguageSvc?Domain=xxxx&SYS=Care&LatestTime=&SVC= HTTP/1.1"
Oct 14 14:31:19 localhost haproxy[11601]: xxx.xxx.xxx.xxx:50115 [14/Oct/2015:14:31:19.225] http-in console/Console 0/0/0/104/104 200 3948 - - --NI 1/1/0/1/0 0/0 "GET /Console/CareLoginSvc?AgentID=91007@xxxx&Password=8BA0FC9468973A97956AA849462406C2&ExtNo=7603&Lang=ja_JP&SVC= HTTP/1.1"

調試日誌顯示任何錯誤跡象。

以下是調試日誌結果的一部分。

/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/etc/haproxy.cfg -d -V
Available polling systems :
      epoll : pref=300,  test result OK
       poll : pref=200,  test result OK
     select : pref=150,  test result FAILED
Total: 3 (2 usable), will use epoll.
Using epoll() as the polling mechanism.

有人猜測為什麼 HA 代理會丟棄某些請求嗎？
