timeout http request ：在客户端建立连接但不请求数据时，关闭客户端连接
timeout queue ：等待最大时长
timeout connect： 定义haproxy将客户端请求转发至后端服务器所等待的超时时长
timeout client：客户端非活动状态的超时时长
timeout server：客户端与服务器端建立连接后，等待服务器端的超时时长，
timeout http-keep-alive ：定义保持连接的超时时长
timeout check：健康状态监测时的超时时间，过短会误判，过长资源消耗
client_timeout 是 app 连接 haproxy的时间
server_timeout 是haproxy 连接后端的时间.
目前发现 超时后,前台一个点击 haproxy 会收到两个相同的请求,原因待查明。
设置 5秒超时时:
timeout connect 5000
timeout client 50000
timeout server 50000

timeout check 5s
