Hello there,

We share servers with load balancer. Our load balancer is working without session stickiness. It causes a mess in the sessions. We can see the following error from the logs. Has any improvement been made on this subject?
The version we used is 4.70

Thanks in advance for your support.

Hi,

In folder Grand.Web\App_Data\DataProtectionKeys you can find keys. Copy this directory from one server to other machines.
They should be the same on all servers.

Hello there

I defined the key to all servers, but when I restart any of the servers, it causes a problem. Your new version also mentions this setting "RedisCachingEnabled". I think this is the solution for me. But how can I get this improvement for 4.70.
