• send_timeout :发送数据至客户端超时, 默认60s, 如果连续的60s内客户端没有收到1个字节, 连接关闭
  
• proxy_connect_timeout: nginx与upstream server的连接超时时间
  
• proxy_read_timeout: nginx接收upstream server数据超时, 默认60s, 如果连续的60s内没有收到1个字节, 连接关闭
  
• proxy_send_timeout: nginx发送数据至upstream server超时, 默认60s, 如果连续的60s内没有发送1个字节, 连接关闭
  

so_keepalive=on|off|[keepidle]:[keepintvl]:[keepcnt]

so_keepalive=30m::10
  will set the idle timeout (TCP_KEEPIDLE) to 30 minutes, leave the probe interval (TCP_KEEPINTVL) at its system default, and set the probes count (TCP_KEEPCNT) to 10 probes.
