hi all is there a way to get a unique index of the current worker process via a variable? (e.g. 0,1,2,3 for 4 workers) i want to use it as a memcache prefix, therefore i cannot use $pid because this changes upon restart. any clues, thx Posted at Nginx Forum: http://forum.nginx.org/read.php?2,32750,32750#msg-32750
