Is it true to say that every worker process in nginx has its own  
round-robin  
counters and that they are not aware of the other workers counters?

Thanks!

Yes, take a look at ngx\_http\_upstream\_round\_robin.c.

Thanks, it’s been a while since I last developed in c, so I wanted  
someone else’s opinion.  
I saw that there is a fair round-robin module and I also saw that it  
uses shared memory to store something. Does it mean that using that  
module counters and servers state (either it is up or down) are  
shared?
