   > You can check to see if tomcat is actively disabling keep-alive.
   
   
   
   > Your problem is that the response header of the APISIX proxy request has 
`connection:keep-alive`, but the log printed by `log-util` is `connection: 
close`, right?
   > 
   > By the way, the communication between `apisix` and `upstream` nodes is 
keepalive. Please see here:
