We have 3 servers: Server_web1,Server_web2 and Server_ngix.
An asp.net application is installed on the servers Server_web1 and Server_web2
The server Server_ngix processes client requests and executes round-robin load balancing

The session state is stored in the data base (it's configured in according with the article)
aspnet_regsql -d SessionStateDb -ssadd -S msserver -U sa -P 1 -sstype c
My web.config
The problem is that two sessions are created for one client: SessionId1 on the server Server_web1 and SessionId2 on the server Server_web2, but one session is needed for each client.
