Hello, I hope this is the correct place to post this question as I have not been able to resolve the problem via archives or Google. We have a setup with one ZEO server and two ZEO clients. The goal is to put a load balancer in front of the two clients and have them both operate off the same session data so that it appears as a single server to the end user. We setup the clients according to: http://longsleep.org/howto/sharesessionwithzeo However, when we run the setup whenever ZEO client 1 is hit for a page a KeyError is generated. I assume this is because ZEO client 2 set up the session and the data is not being shared. I upgraded us to Zope 2.7.4 last night in an attempt to fix the problem. Any help is greatly appreciated. Thank you in advance. Best Regards, Jason
