We have two nopCommerce sites. One of them is on nopCommerce 3.6. We host this site in Azure in a multiple-server environment. If I enable both servers on our load balancer, I can see requests being sent between the two. Cool. However, authentication information seems to get lost: if I authenticate on Server A, Server B is unaware and I lost my authentication if I'm handed off to that server.
I have a Redis cache section in the config file on both servers that was written by a different developer. I've read that there is a MultipleInstancesEnabled config setting on 3.7.
Is sharing cache with Redis possible on 3.6? Because of customizations for our internal ERP system and process, upgrading beyond 3.6 isn't possible right now.
Thanks for any advice!
