 connect： 定義haproxy將客戶端請求轉發至後端伺服器所等待的超時時長timeout client：客戶端非活動狀態的超時時長timeout server：客戶端與伺服器端建立連線後，等待伺服器端的超時時長，timeout http-keep-alive ：定義保持連線的超時時長timeout check：健康狀態監測時的超時時間，過短會誤判，過長資源消耗client_timeout 是 app 連線 haproxy的時間server_timeout 是haproxy 連線後端的時間.目前發現 超時後,前臺一個點選 haproxy 會收到兩個相同的請求,原因待查明。設定 5秒超時時:
