960	TCP connection re-use without upstream conf	diwakar.jois@…		"Hi, 

        We are using nginx as a http proxy. 
	We have to connect to only a couple of http servers. 
	There is high load generated from the clients. We want to reuse the TCP connections. 
	This can be acheived by adding upstream servers (as described in https://ma.ttias.be/enable-keepalive-connections-in-nginx-upstream-proxy-configurations/ ). 
	But the list of http servers can change. 
	Please let us know if there some configuration using which we can re-use TCP connections without needing upstream server configuration. (From https://www.ruby-forum.com/topic/4486861 I understand that dynamic configuration of upstream servers is not possible.)
	If it is not supported yet, please enhance nginx so that with a new configuration tcp connections could be re-used without needing upstream server configuration.
		
With Best Regards,
Diwakar
