Hi all,

First time posting here so apologies for any faux pas etc…

I have an nginx config where I have a server block, a location block and  
a  
proxypass in the location block, pointing to an upstream.

The upstream has, at this point 3 servers in it.

All the 3 servers are in the same vpn. The proxy\_pass directive pointing  
traffic to that upstream uses the http protocol

I want to add another server into the upstream endpoints, located in a  
remote datacentre. I want traffic to this remote datacentre to be  
encrypted  
over https.

The proxy\_pass can’t handle http and https simultaneously

Any ideas how I can have an upstream containing the 3 servers in the  
local  
datacentre that shouldn’t use https, and the 1 server in the remote  
datacentre that does need the traffic to be encrypted with https,  
please?

Someone suggested putting a server definition in the upstream that  
directs  
to a local nginx server definition that’s designed to just forward off  
to  
another upstream with an https proxy\_pass command, with the second  
upstream  
holding the remote datacentre server definition but it seems a bit  
kludgy.

Thanks for any advice!

Steve
